How is bacteria useful to us?

Answer 1

This is a multifaceted subject. Concisely stated, we CANNOT survive as a species without bacteria. They are all around us and ON us. Bacteria living on our skin protect us from external pathogens by fighting off virulent agents, e.g. harmful bacteria that can cause skin infection, fungi, parasites. They also maintain healthy skin pH levels. The bacteria in our digestive tract also protect us from pathogens, aid our digestion, and they also participate in the synthesis of various vitamins. These bacteria in and on our bodies are symbiotic (we are mutually beneficial to each other), and they are ESSENTIAL for human life. Aside from that type of bacteria, other types are used industrially: food production (cheeses and other foods requiring fermentation), alcohol production, creation of certain medicines, etc.
