Bacteria like Bifidobacteria, Escherichia coli, and Lactobacillus have been found to be beneficial for our system, they help in regulating the immune system, synthesis of vitamin K2, protects against carcinogens, etc. On the other hand, bacteria like Clostridium have negative impact on our system.

In case of fungi, not all microscopic fungus cause harm to humans. In fact, we consume many products which have been fermented or brewed using yeast. Yeast essentially takes simple sugars like glucose and maltose and pro...
