Do probiotics encourage the growth of good bacteria?
Probiotics
Forms
Supplement: Dietary supplements uses probiotics in a freeze-dried powder form. They put these powders in tablets, capsules, sachet, and stick packaging. (National Library, 2019)
Fermented foods: Bacteria/probiotics can come from foods as stated before more examples of fermented foods are Kimchi, Miso, Tempeh, and Sauerkraut. all these are fermented. (Christina Vetter, 2026)
Effects On Body
Restore: Probiotics can restore the balance of bacteria in individuals gut. This includes the stomach and intestines. They do this when your stomach had been effected by illness or treatment. (NHS, 2022)
Boost: Probiotics allow for boosts in individuals immunity against infections, improves digestion, and protection against harmful pathogen. (Cleveland Clinic, 2023)
Phases (Sydni Rubio, 2025)
Tolerance: As you eat more probiotics or get them from another source they will build up and adjust to the individuals gut.
Maintenance: Probiotics will continue to maintain the human body, It prevents the bad bacteria from coming back and support overall gut health.
Deep Support: Probiotics will restore, build, and sustain the individuals digestion, immune system, stomach, and intestines.
Sources
Natural foods: You can find probiotics in fresh fruit, vegetable, and whole foods. Although these foods carry small amounts of prebiotics making less effective than fermented foods or supplements. (Probiotic Foods,2023)
Water Kefir: Water Kefir is a drink alternative source of probiotic. This is for people that are lactose intolerant , vegan individuals, and individuals with allergies. (Gizem Cufaoglu, 2023)
Supplement and laboratory: Laboratories grow specific probiotic bacteria under specific controlled environments. By doing this it ensures that the bacteria is safe, effective, and pure. These grown bacteria is added in foods and supplements. These supplements are then ingested by indivisuals. (NIH, 2025)
Environment: By consuming unwashed vegetables it can introduce healthy soil-basted bacteria in the digestive system. If you live in Rural spaces like a farm, the contact of nature exposes individuals to ranges of microorganisms. Gardening transfers beneficial microbe to skin and mouth. (NIH, 2016)
Human Body: The body create natural occurring probiotics. They live natural in individuals gut, mouth, and skin. it can also form in a pregnant females breast milk. it has beneficial bacteria. (NIH, 2022)
Characteristics
Are microorganisms
Are alive
They are administered
In sufficient amounts
Has health benefits
Types
The 4 group species of bacterial probiotics are Lactobacillus species, Bifidobacterium species, Streptococcus species, and Enterococcus species. (Mathieu Millette, 2024)
Characteristics (ISAPP, 2025)
Outsides of each bacterial probiotic is different. It prompts distinct responses from digestive and immune systems.
Bacterial Probiotics are classify probiotics with genus and species. They are classified by their strains.
Bacteria
Good
Sources
Fermented foods: Fermented foods that have bacteria with probiotic potential is added during manufacturing process or adventures bacteria like cheese. These good bacterial thrive on fermented foods. (Franck Gael Carbonero, 2022)
Sourdough Bread
Kimchi
Yogurt
Lifestyle: Consuming foods with the right nutrients provides the good bacteria growth. Foods like yogurt help restore balance. Nutrients that grow good bacteria is fibre, polyphenols, fermented foods, and prebiotics (Banana). Better Health, 2026)
Environment: Good bacteria is produced through natural exposure. you can find these bacteria in soil, water, plants, food, and air. when we interact with these things small bacteria enter our bodies. They help build gut and skin microbiomes. (Don A Cowan, 2022)
Types
Lactobacillus: Is a friendly bacteria that produces lactic acid as a by-product of glucose metabolism. It helps break down lactose, helping symptoms of lactose intolerant, supports individuals gut health, and digestion. (Diary Australia)
Akkermansia muciniphila: This bacteria maintains your mucus layer and generates metabolites that benefit your metabolism and immunity. You can find this in individuals that have diseases like type 2 diabetes and colorectal cancer. it also regulates the gut-brain axis in living organisms. (Dr Juneau, M.D, FRCP,2023)
Bad
Sources
Contaminated Water: When water sources travel through pipes leading to water supplies aren't filtered properly or crack in pipe, will lead to contaminated water. Germs and chemicals can get into taps water, examples being rocks and soil carrying chemicals, leaks from landfills, wildlife, and fertilizers. (CDC,2024)
Animals and Vectors: Bacteria is transmitted by vectors. Once a vector is contaminated it becomes infectious most the time and they can transmit the pathogen for the rest of their life. an example is mosquitos when they have blood meals and ingest disease producing microorganisms. when they later have another feed transmit that pathogen. (World Health Organization,2024)
Contaminated foods: Biological hazards( bacteria), chemical hazards (Cleaning chemicals, natural food toxins), and physical hazards (physical objects in food) are how foods become contaminated. Food poisoning is most common, if a foods not prepared properly (Temperature), Hygiene isn't done (Washing hands) or different objects are used to cut different foods (Cross-contamination), all cause bad bacteria to grow. (DoFoodsSafely, 2025)
Types
Salmonella: An infection is common bacteria disease. It effects individuals intestinal tract. They live in human and animals intestines. People get diarrhea, fever, and stomach craps. This happens 8-72 hours after exposure. (MayoClinic, 2025)
Escherichia coli: A group of bacteria that lives in the gut of healthy organisms. They cause infections, stick to cells, and release bad toxins. Symptoms are nausea, vomiting, fagtige, fever, diarrhea, and stomach pains. (Cleveland Clinic, 2023)
Ways to test Growth
Petire Dish
Limitations: Limitations of using a petire dish is there is a risk of contamination when conducting the practical. The surface area is also limited but its only a problem if you need large experiments. This experiment doesn't have the simulation of the real environment/gut. The result may be different if they were to be in the body or a control environment experiment. (SSCT.2025)
Advantages: Advantages to using petire dishes are its easy to see the bacteria growth as its flat and transparent, you can create conditions that allow microbes to growth consistently, and they are coat effective and easy to use. (SSCT, 2025)
Test tube
Limitations: Limitations to using test tubes are its hard to identify individual species, hard to isolate pure bacteria, you cant see how the bacteria looks, their characteristics, and its hard to see how much bacteria grew, cant count exact numbers. (NIH, 2019)
Advantages: Advantages to using test tubes are that bacteria grows fast and easy in liquid, due to nutrients being available. Its good to measure bacteria over time, and is useful to test different oxygen conditions. (Linda Vidova)
