Explanation:
Detailed explanation-1: -Heterofermentative process Heterofermentative bacteria produce less lactate and less ATP, but produce several other end products: glucose + ADP + Pi → lactate + ethanol + CO2 + ATP. Examples include Leuconostoc mesenteroides, Lactobacillus bifermentous, and Leuconostoc lactis.
Detailed explanation-2: -Homofermentative LAB includes Streptococcus, Lactococcus, Enterococcus, Pediococcus, and some Lactobacillus, as shown in Table 1.
