Explore the fascinating world of microbes, including beneficial bacteria like lactobacilli and rhizobium, and harmful ones like clostridium. Learn about fermentation, antibiotics, food spoilage, and how microbes impact health, agriculture, and industry.

Microorganisms are tiny living organisms found everywhere—in air, water, soil, and even inside our bodies. They include bacteria, fungi, protozoa, algae, and viruses. Some are beneficial, helping in food production, medicine, and agriculture, while others cause diseases and food spoilage. Microorganisms play a key role in nitrogen fixation, environmental cleanup, and food preservation. Proper hygiene and vaccination help prevent the spread of harmful microbes.
