Bacteria are omnipresent in the biosphere, and their plasmids, which are common in pathogens, can be easily taken up by diverse environmental bacteria, providing pathways for the exchange of nutrients. These bacteria create pollutants and toxins that harm the environment, and 99 of all microbes are pathogenic. Gene expression in bacteria is very similar to gene expression in humans, which facilitates the use of bacteria in various ways.
The effects of microbes on their environment can be beneficial or harmful, depending on human measure or observation. Microbes adapt to abiotic and biotic factors such as temperature, pesticides, and interactions. Excessive hydrogen peroxide is harmful for almost all cell components, so its rapid and efficient removal is essential for aerobically living organisms. Mn-catalases (E.C.) are essential enzymes needed for breaking down food and using its nutrients to power and repair our tissues and organs.
The microbiome plays a crucial role in the One Health domain, facilitating interactions among humans, animals, and the environment, along with co-evolution. Bacteria are ubiquitous due to their metabolic activity and can grow in any environmental conditions and produce enzymes. Some aerobic bacteria, like Mn-catalases, can break down and transform harmful environmental pollutants into less harmful substances.
While most bacteria are beneficial to human health, some are pathogenic and can cause mild to severe infections. Some types of bacteria can cause problems for the human environment, such as corrosion, fouling, water clarity issues, and bad smells. Anaerobes, or anaerobic bacteria, outnumber our own cells ten to one. While some microbes cause disease, most are harmless or even helpful, and good bacteria in our bodies play a vital role in maintaining overall health.

📹 How Bacteria Rule Over Your Body – The Microbiome
What happens when microbes talk to your brain? OUR CHANNELS …
Are bacteria always harmful to humans?
Not all bacteria are harmful. Some bacteria that live in the body are helpful. For instance, some bacteria that live in the intestines, help digest food, destroy disease-causing organisms and provide nutrients.
But bacteria may also cause illness. Many disease-causing bacteria make powerful chemicals called toxins that damage cells and make you ill. Other bacteria can get into and damage tissues. Some infections caused by bacteria include:
- Strep throat.
- Tuberculosis.
- Urinary tract infections.
Viruses. Viruses are much smaller than cells. In fact, viruses are just capsules that hold genetic material. To reproduce, viruses invade cells in the body. They take over the process that makes cells work. In time, host cells often are destroyed during this process.
Are all microbes harmful to humans?
Microscopic creatures—including bacteria, fungi and viruses—can make you ill. But what you may not realize is that trillions of microbes are living in and on your body right now. Most don’t harm you at all. In fact, they help you digest food, protect against infection and even maintain your reproductive health. We tend to focus on destroying bad microbes. But taking care of good ones may be even more important.
You might be surprised to learn that your microbes actually outnumber your own cells by 10 to 1. “The current estimate is that humans have 10 trillion human cells and about 100 trillion bacterial cells,” says Dr. Martin J. Blaser at the New York University School of Medicine.
New techniques allow scientists to study these rich microbial communities and their genes—the “microbiome.” In 2007, NIH launched the Human Microbiome Project to study microbes in and on the body.
Why are enzymes bad for the environment?
Enzymes are proteins which are readily and ultimately biodegradable in the environment.
Apart from aquatic toxicity resulting from of the catalytic effect (protein degradation) inherent to protease enzymes there is no environmental hazardous effect from enzymes in the environment. As enzymes are quickly inactivated and biodegraded already during transport to and treatment in occupational waste water treatment plants and municipal sewers and sewage treatment plants. This aquatic toxicity is not relevant to the environment.
The fact that there are no hazardous waste products makes industrial enzymes the most environmentally friendly solution to most industrial problems.
Which enzyme is present in bacteria?
The bacterial enzymes acetate kinase (AK) and phosphotransacetylase (PTA) form a key pathway for synthesis of the central metabolic intermediate acetyl coenzyme A (acetyl-CoA) from acetate or for generation of ATP from excess acetyl-CoA. Putative AK genes have now been identified in some eukaryotic microbes.

How is bacteria harmful to the environment?
Aerobes, or aerobic bacteria, can only grow where there is oxygen. Some types can cause problems for the human environment, such as corrosion, fouling, problems with water clarity, and bad smells.
Anaerobes, or anaerobic bacteria, can only grow where there is no oxygen. In humans, this is mostly in the gastrointestinal tract. They can also cause gas, gangrene, tetanus, botulism, and most dental infections.
Facultative anaerobes, or facultative anaerobic bacteria, can live either with or without oxygen, but they prefer environments where there is oxygen. They are mostly found in soil, water, vegetation and some normal flora of humans and animals. Examples include Salmonella.
Mesophiles, or mesophilic bacteria, are the bacteria responsible for most human infections. They thrive in moderate temperatures, around 37°C. This is the temperature of the human body.
What are bacterial enzyme?
- Bacterial enzymes are proteins that are responsible for performing various catalytic operations.
- Bacterial enzymes are responsible for the degradation of proteins into their component of amino acids.
- The process is known as proteolysis.
- Proteolysis occurs at different rates for the different types of proteins that are present in the body.
- In order to perform the catalytic operations, bacterial enzymes are involved.
- There are many microbes living in soil environments that secrete proteases to break down proteins into amino acids and peptides that can be transported into the cell.
What are the negative effects of enzymes?
Other side effects of digestive enzymes include:Stomach pain. Headache. Gas. Constipation. Cough. Sore throat. Diarrhea. Upset stomach.
What conditions are digestive enzymes (PEPs) used to treat?;
What are the side effects of oral digestive enzymes?;
How would not having enzymes be harmful to bacteria?
If bacteria did not create enzymes, complex substrates would take too long to disintegrate into consumable products, and the bacteria would not be able to eat enough in a short enough period of time to survive and reproduce.
Bacteria and Waste. The complex substrates that enzymes act on and bacteria then consume include waste compounds that pollute the environment, such as those listed in the table above. Even substrates that sound relatively harmless, like starch, can and do wreak havoc on the planet and its inhabitants.
Biological remediation is a process through which safe bacteria are selected for the enzymes they produce and are purposefully introduced in a given location in order to remove a specific harmful waste. During this process, bacteria and enzymes work hand-in-hand, and the byproducts of digestion are more bacteria, water, and carbon dioxide, which are natural and inherently harmless. The bacteria continue to reproduce until the bacteria’s food is eliminated.
Is it true that all bacteria make you sick?
There are many different types of bacteria. Most types don’t make you sick. Some types are helpful. For example, “good” bacteria in your digestive system can help your body digest food and absorb vitamins and minerals. They can help protect you from getting sick. Bacteria are also used in making foods like yogurt and cheese.
But some types of bacteria can cause an infection and make you sick. They are called infectious bacteria. These bacteria can reproduce quickly in your body. Many of them give off toxins (poisons) that can damage your cells and make you sick. Other types can move into and damage your tissues. A few examples of bacteria that cause infections include Streptococcus, Staphylococcus, and E. coli.
How do bacterial infections spread?. There are different ways that bacterial infections may spread:
Are humans 99% microbes?
Given that fact, it shouldn’t surprise us that microbes occupy most of us as well. Seventy to ninety percent of all cells in the human body are bacterial, representing perhaps 10, 000 different species. Genetically we get even less real estate: 99 percent of the unique genes in our bodies are bacterial. This population of over 100 trillion microorganisms makes up our microbiome: a collection of microbial communities that has evolved along with homo sapiens to help orchestrate basic life processes, beginning the moment we’re born.
So it really shouldn’t surprise us that the microbiome plays a major role in health, especially immunity and metabolism. Nor that disrupting this ancient equilibrium could have serious consequences. But that was the last thing on anyone’s mind when antibiotics, which destroy bacteria or slow their growth, came on the scene in the 1940s. “We’d just won World War II, we had dropped the bomb, we were invincible, and now we had these incredible drugs,” says Blaser. Formerly lethal diseases could be prevented or cured. Surgery grew far safer. Side effects appeared to be few and mild.
An estimated 30 trillion cells in your body—less than a third—are human. The other 70-90% are bacterial and fungal. Gaby D’Allesandro/© AMNH.
Are bacteria harmful to human beings briefly explain this statement?
If you consume or come in contact with harmful bacteria, they may reproduce in your body and release toxins that can damage your body’s tissues and make you feel ill.
Harmful bacteria are called pathogenic bacteria because they cause diseases and illnesses, such as:
- Strep throat
- staph infection
- cholera
- tuberculosis
- food poisoning
In some cases, you may need antibiotics to stop pathogenic bacteria from reproducing and harming your body. It’s important to receive an accurate diagnosis from your doctor since antibiotics only get rid of bacteria and can’t treat viral or fungal infections.
Antibiotic resistance is an increasing concern, and you may be at a higher risk if you take antibiotics when they aren’t necessary. Bacteria may evolve and learn to become resistant to antibiotic treatments.

Hey kurzgesagt, I’ve been perusal your articles for over 5 years now and you don’t know how much these articles help me out… Every single time, and I mean every single time I have episodes of depression or anything of the sort I can always look up to this website to brighten up my day; So I just wanted to write this to you as a token of gratitude and appreciation at all the great content you post.
When I started a keto diet, there were a couple of days where I felt depleted. But the most interesting event were the incredibly vivid dreams I had about pasta, bread, sugar etc. I genuinely think that the dying bacteria I was depriving of sugar and carbs were signalling my brain to want those foods. I would love to hear your experience.
The idea that trillions of bacteria are swarming over your skin and through your body is enough to give anyone the creepy crawlies. But In fact, We get more nutrition out of our food because of bacteria. This article does a great job of explaining the presence of bacteria in us without grossing us out. Kudos !
An observation at 5:56, it’s said that “our microbiome has also been linked to other serious diseases, as autism”. Autism isn’t a disease (and that was mentioned on the article in the same sentence that included cancer), it’s a disability. It’s not considered a disease because it’s not something to be cured. Autistic people may need more or less support in certain situations, but they also have their own way of being (specific interests, stims, personality) and if no one is being harmed by that, that’s okay. I thought it’d be important to mention this, specially as an autistic woman.
This shit makes me cry. Being depressed at times of my life and dealing with self hate at points for not being better, yet perusal this realizing all these creatures only job is to live alongside us. Some help, others are indifferent. But it’s all an ecosystem. It’s just so amazing to think this is what being a live human being is. I wish others could see through my eyes.
I’m so used to perusal Kurzgesagt articles on things I don’t know about that it made it an interesting experience to watch one on things I already know about. It really gives you some insight on how much of a nutshell the content really is. As always though, excellent article Kurzgesagt – In a Nutshell.
Kurzgesagt, I was rewatching your first article earlier today! Even back in 2013 your articles were really, really good but comparing them to your latest ones, I have to emphasize heavily that you have made a stunning progress over the years! You are an inspiration to our website and, I believe, to many others as well!
i don’t think autism should’ve been counted as a ‘serious disease’ alongside *cancer*. i say this as an autistic person who’s become fascinated by your articles ever since i discovered them the other night. your articles always inspire me, but i don’t want to know if you think my way of thinking/feeling is a problem.
Autism is not a “disease”. It is simply a different way of thinking. This common but debilitating misconception affects autistic folk like myself in a very personal manner. Diseases are biological – autism is a different way of thinking. For example, autistic people who can’t speak don’t have vocal abilities because their brain simply isn’t vocally wired the way a neurotypical person’s brain is, not because of some voice box rot. I love your website and its exploration of existential questions – my favorites are articles on the possibility of aliens and the Fermi paradox – but I would encourage you to refrain from such misconceptions in the future.
I’ve often heard that the appetite of the mother during pregnancy affects the food preferences of the child. For example, while my mom had me, she had a big craving for tomatoes. My dad even had to buy a pack of them while she was in the hospital. I personally love both tomatoes and ketchup, even from my childhood. Could this be due to the bacteria and immune system being carried over from my mom?
6:00 – “has been linked to other serious diseases like autism (etc)” For the love of…*sigh* Autism. Is. Not. A. Disease. (I’m autistic – people like me are in the neurological minority, and sometimes have a lot of struggles due to this or issues that often accompany being autistic, but we are not seriously or even not-so-seriously diseased. We get enough of that crap from Autism $peaks & similar organizations. And your articles are awesome, and watched by millions of subscribers & other viewers…but that also means that millions of people just heard (again!) this idea that to be autistic is to be diseased/defective/damaged/broken/lost/MSSNG/”a puzzle”/a plague/crisis/tsunami/etc/etc/etc. (And please don’t bring functioning labels in if you respond to this comment. The autistic community includes all autistics, no matter how much support they need or don’t need, & they can all speak for themselves if given the opportunity to communicate in their preferred method. And autistic self-advocates are pretty dang unified so far as this goes. There are exceptions to every rule, but I feel it’s safe to say any autistic who doesn’t struggle with internalized ableism would respond vehemently if someone said they “had a serious disease.”) ASAN (the Autistic Self-Advocacy Network) is a great resource, btw, for any autistics or allies looking for more information. 🙂

To everyone saying Autism isn’t a disease in the comments. It is. Look up the word disease. In a standard dictionary: dis·ease dəˈzēz/ noun noun: disease; plural noun: diseases; noun: dis-ease; plural noun: dis-eases a disorder of structure or function in a human, animal, or plant, especially one that produces specific signs or symptoms or that affects a specific location and is not simply a direct result of physical injury. In a Medical Dictionary: dis·ease dəˈzēz/ noun noun: disease; plural noun: diseases; noun: dis-ease; plural noun: dis-eases 1 a condition of abnormal vital function involving any structure, part, or system of an organism. 2 a specific illness or disorder characterized by a recognizable set of signs and symptoms attributable to heredity, infection, diet, or environment. Autism is a disease. It is in fact the thing this word is describing. As an autistic person, it bothers the shit out of me that you guys don’t use words correctly. Please read the dictionary and use the proper words to convay your thoughts so we can all understand each other without having to resort to that context clue voodoo.
How come you didn’t mention antibiotics? It’s known that they kill both good and bad bacteria, which gives a chance for other micro-organisms such as yeasts to start rapidly repdroducing. Taking antibiotics for a long time means that you also wipe out many of the good bacteria and gut flora can change a lot even permanently.
I’d like to educate and correct the part where autism is referred to as a disease. This is shedding an unjustified light on what is essentially who somebody is. You can’t catch autism, it’s not a disease. A person can be autistic but this does not mean they are infected, it’s a description for their patterns of behavioues.
This article made me think of that saying people have that we only use half of our brain. I didn’t think it was true but if these organisms were sending messages to our brain you’d think you could hear them or something idk, makes me question if it’s actually true or not. Anyway love these articles so much one of my favourite websites 💜💜
Kudos to animators and whoever wrote the script, you’re amazing.I knew eating habits are because of some kind of connection between our gut and brain and not tongue or taste (not directly atleast). It’s those bacteria that are ordering pizza at 2 am and I think the bacteria are craving for some chocolate cake right now. This is gutception of cravings.
Simply FREAKIN amazing! Say! Is there one about smoking? I’m having a very hard time quitting and can’t afford quit candy. I could use the extra motivation. I had heard from one of my homies that is an intern said they had cut this dead guy open and they could tell immediately that he was a smoker because his lungs smells like an ashtray.
I liked most of the article, but I’m quite offended about the part where they call autism a ‘severe disease’… Autism is something you are born with. If your micro biome is whack, it might cause specific symptoms of autism or make someone’s autism more noticeable, but if you show some symptoms (or not) that doesn’t determine whether someone is autistic or not. Its just a neurological difference, and it’s not a disease.
