Answer 1

Answer:

Turning milk into curd...

Bacteria like Lactobacillus helps in the production of lactic acid from lactose which is essential in the formation of curd. It lowers the pH of the milk which helps in coagulation of protein and forming the curd.

Making bread rise...

Yeast is a microbe used in bread making which feeds on sugar. Enzymes in yeast ferment sugar forming carbon dioxide and ethanol. The carbon dioxide makes the bread rise, while the ethanol evaporates when the bread is baked.

Cleaning drain pipes..

Under the process, bacteria are cultured in bulk and applied to the flowing sewage. ... These microbes consume the organic mass of the waste water and utilize the nutrients from sewage for their growth, ultimately enhancing the cleaning action of waste water.

Making manuer...

Microbes such as bacteria and fungi are responsible for generating carbon dioxide, water and heat by the break down of organic matter during the process of composting. These microorganisms break down the soluble and readily degradable substances present in the organic matter by the use of different enzymes.
