The document discusses the roles of microbes in sewage treatment, biogas production, and as biocontrol agents and biofertilizers. Microbes play key roles in breaking down waste in sewage treatment plants and converting organic materials into biogas through anaerobic digestion. They also act as natural enemies to control agricultural pests and help fertilize soils by fixing nitrogen and making nutrients available to plants.
