What are the main topics covered in Microbes in Human Welfare for NEET 2026?

This NEET 2026 syllabus section includes the role of microbes in household products (curd, bread, cheese), industrial products (citric acid, alcohol), sewage treatment, biogas production, and as biocontrol agents and in biofertilizers.

How do microbes help in producing curd and bread?

Lactic acid bacteria (LAB), like Lactobacillus, ferment lactose in milk to produce lactic acid, which coagulates milk proteins to form curd. In bread making, yeast (Saccharomyces cerevisiae) ferments carbohydrates, producing carbon dioxide gas that causes dough to rise.

Which group of microbes produces methanogens?

Methanogens are a group of Archaea, typically anaerobic bacteria, that produce methane as a metabolic byproduct in environments like the digestive tracts of ruminant animals and in sewage treatment plants.

What is streptokinase and which microbe produces it?

Streptokinase is an enzyme produced by the bacterium Streptococcus pyogenes. It is used medically as a 'clot buster' to break down blood clots and prevent heart attacks.

Can you name some common biocontrol agents derived from microbes?

Yes, examples include Bacillus thuringiensis (Bt) for controlling insect larvae, ladybugs and dragonflies for aphid control, and certain fungi like Trichoderma for controlling plant diseases.

How are microbes used in sewage treatment?

Microbes are crucial in both primary and secondary treatment. Aerobic and anaerobic bacteria break down organic matter in sewage, reducing its biochemical oxygen demand (BOD) and converting it into less harmful substances and biogas.

What are biofertilizers and how do they work?

Biofertilizers are preparations containing living microorganisms that, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promote growth by increasing the supply or availability of primary nutrients to the host plant. Common examples include bacteria like Rhizobium and cyanobacteria.

Are there questions related to antibiotic production in these MCQs?

Yes, the MCQs cover microbe-based production of important industrial products, including antibiotics like penicillin, which are vital for understanding microbial applications in medicine for exams like NEET 2026.
