Why is fermentation crucial for various aspects of human life?
Use of fermentation if food
In drinks:
Wine
Beer
Kombucha
Milk
Soy Sauce
In food:
Breads
Yogurt
kimchi
Sauerkraut
Cheese
Olives
Cultivating Bacteria for human benifit
Reasons For Fermentation
Taste
Preservation
Useful Bacterial
Killing of bad bacteria
Creation of alchohol from sugar
Sugars in dough into carbon dioxide
Healthy Bacteria(Probiotics):
Lactobacillus
Gluconacetobacter
Gluconobacter
Lactic Acid Bacteria
Overpopulating the culture of bacteria with just Lactic acid bacteria
In olvies we use fermentation to make them more edible. This improves taste and removes the bitterness
Fermenting milk can save it from spoiling or make use of spoiled milk
Types of fermentation:
Acetic acid fermentation
Ethanol fermentation
Lactic acid fermentation
bacterial fermentation
Human Biological Processes
Autobrewery Syndrome
Gut Flora:
Firmicutes
Bacteroidetes
Actinobacteria
Proteobacteria
Fusobacteria
Verrucomicrobia

what causes lactic acid buildup in the body :
Negative effects of fermenation
Cultivation of
E.Coli
Samonella
Botolism
Using Pasteurization to prevent unwanted organisms in food
How do we prevent harmful bacteria in Fermentation?
https://fermentationassociation.org/the-safety-of-fermented-food/
Lactic Acid Bacteria.
These introduce Lactic Acid to the fermented food, decreasing PH making it acidic. This becomes a harmful enviroment for most pathogens and bacteria.
The best way to harbour Lactic Acid Bacteria is through salt brines, they thrive in high salt concetration.
Temperature
To prevent further replication of harmful bacteria it is best to
Ferment in an environment between 20-23C
Heating to kill off all bacteria after fermentation (mainly in yoghurt)
Definitions
Fermentation:
the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.
All fermentation is without oxygen
