Statement 1: Paneer or cottage cheese is produced by curdling milk
Statement 2: Bacteria is be used for tanning of leather
Both the statements are true
Some cheeses are curdled only by acidity. For example, paneer cheese is made using lemon juice to curdle the milk and cottage cheese is made using mesophilic bacteria. However, for most cheeses, rennet is also added to the milk after a starter bacteria.
Animal proteases and microbial proteases from bacteria and fungi are used in the pre-tanning processes of leather manufacture.
