Lactobacillus mediated conversion of milk to curd results because of
1 coagulation and partial digestion of milk fats
2 coagulation and partial digestion of milk proteins
3 coagulation of milk protein and complete digestion of milk fats
4 coagulation of milk fats and complete digestion of milk protein
Explanation:
Lactobacillus is a genus of gram-positive facultative anaerobic bacteria. Lactic acid bacteria grow in milk and convert it to curd. During growth lactic acid bacteria produce lactic acids that coagulate and partially digest the milk proteins.

A microbial mutant requiring growth factor in addition to minimal medium is :
1 Auxotroph
2 Heterotrophy
3 Autotroph
4 Syntroph
Explanation:
Auxotrophic mutants cannot grow in minimal medium if the additional nutrients are not supplied, because it lacks a certain growth substances (amino acid or vitamin).

Milk is changed into curd by:
1 Lactobacillus
2 Acetobacter aceti
3 Bacillus megaterium
4 None of these
Explanation:
Production of curd from milk is done by a micro-organisms such as Lactobacillus and others commonly called lactic acid bacteria grow in milk and convert it into curd. These bacteria convert lactose sugar of milk into lactic acid that coagulates the milk protein casein.
