Microbes are nothing but a short form of microorganisms. They are so small that they cannot be seen without any microscope. Some of the common microbes are bacteria, green algae, fungi, protists, archaea, and plankton. Microbes are important for the human body as they help nutrients rotate through the natural ecosystems. While certain types of microbes can help make our food inedible through spoilage, some microbes are also important components in food production which can be found in many common foods.
Food that is made using microbes:

Microbes are used in almost all products and medications, but it is mostly used to aid in producing various food and beverages. So, let’s check out some of the foods that are made using microbes:
a) Cheese: Microbes are used in order to produce lactic acid in the ripening process. It is also essential in curdling milk and turning a liquid into a solid food product. Even cheese gains its particular flavor through its ripening process and the addition of bacteria. Each of the cheeses has different bacteria which helps in enhancing the flavor compounds. Mesophilic bacteria is used for cheeses like cheddar, Colby, and feta, while thermophilic bacteria is used in camembert, gouda, and baby swiss.
b) Beer: A type of yeast known as Saccharomyces cerevisiae is added to the wort, a type of liquid that is made of barley, hops, sugar, and water, which later converts the sugar in the wort to alcohol and carbon dioxide.
c) Leavened Bread: The presence of yeast in the dough of the bread causes it to rise in the fermentation process, converting sugar in the dough into water and carbon dioxide.
d) This also makes the dough fill up the air bubbles which forces the batter to rise.
e) Wine: Just like beer, even wine is made using yeast, but instead of using hops and barley, the starter material is grapes.
f) Pickles: Cucumbers undergo a process of fermentation with bacteria which produces lactic acid. The bacteria which was involved in the process include Enterobacter aerogenes, Lactobacillus brevis and L. plantarum, Pediococcus cerevisiae, Leuconostoc mesenteroides, and Enterococcus faecalis. The good bacteria can help prevent harmful bacteria from attaching to the cucumbers giving the pickles their distinct and sour taste.
g) Olives: Olives cannot be eaten until they have undergone a fermentation process with microbes. They are steeped into a live active brine solution that includes Lactobacillus brevis, Lactobacillus plantarum, and Leuconostoc.
h) Yogurt: Lactic acid is made using Lactobacillus bulgaricus and Streptococcus thermophiles which begins its fermentation similarly to the cheese-making process. The microbial then creates the sour flavor in yogurt and breaks down some of the milk’s lactose.
Saccharomyces boulardii is a strain of yeast that has been studied for its probiotic impacts that can help in providing intestinal comfort. The strain survives the gastric acid and bile salts, and it is also stable in providing health benefits to the host.
Potential Uses of Saccharomyces Boulardii
a) Probiotic saccharomyces boulardii is mostly utilized for treating & preventing diarrhea which is also caused by the use of antibiotics and infections. It is also used for general digestion problems, irritable bowel syndrome (IBS), inflammatory bowel syndrome, and bacterial overgrowth.
b) You can also use probiotic saccharomyces boulardii for vaginal yeast infections, lactose intolerance, urinary tract infections (UTIs), fever blisters, high cholesterol levels, canker sores, hives, and teenage acne.
There are many enzymes from bacteria, yeasts, molds, and plant and mammalian sources currently used for processing foods and food ingredients. Some of the yeast species used for the production of proteins are genera Candida, Saccharomyces, Torulopsis, and Methylophilus. Enzymes are produced either by surface culture on solid substrates or by submerged culture using liquid substrates. Commercial enzyme production’s success highly depends on maximizing the activity of the microorganism and minimizing costs of the substrate, incubation, and recovery procedures.
