Explanation:
Detailed explanation-1: -Spoilage of milk and milk products results from growth of fermentative bacteria when storage temperatures are sufficiently high for psychrotrophs. Genera of bacteria producing acids in milk and milk products are Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, and Streptococcus.
