Microbes play an essential role in the production of various household products that we use every day. These tiny organisms contribute to the fermentation and transformation of different food items, enhancing their nutritional value, flavour, and texture. Here are some common examples of how microbes are utilized in household products:

Production of Curd

One of the most common examples of microbial use in households is the production of curd from milk. This process involves:

Microorganisms Involved

Lactobacillus and other lactic acid bacteria (LAB) are responsible for converting milk into curd.

Process

1.LAB grow in milk and produce lactic acid during their growth. This acid coagulates and partially digests milk proteins, transforming milk into curd.

2.A small amount of curd added to fresh milk acts as an inoculum or starter, containing millions of LAB. At suitable temperatures, these bacteria multiply and convert the milk into curd.
