For human beings, the diversity of microorganisms is still an undiscovered
aspect. For the well-being of society, the huge microbial population performs many
vital activities. Microorganisms play an important role in sustainable agriculture,
environmental protection, and human and animal health. Microorganisms have a major
contribution to agricultural issues like crop productivity, plant health protection, soil
health maintenance, and environmental issues like bioremediation of soil and water
from many pollutants. In addition to these activities, microorganisms also produce
many products, either directly or through industrial processes, which are essential for
human survival. In this chapter, we deal with various industrial products that are
produced by microorganisms through different reactions, like antibiotics, enzymes,
natural food preservatives, vitamins, fermentation products, amino acids, and
agricultural products.
Keywords: Antibiotics, Biopesticides, Enzymes, Fermentation, Microbial Biotransformation.
