Answer:
Gut microflora is a combination of many different kinds of bacteria. Out of these, Lactobacillus bacteria, specifically, Lactobacillius acidophilus and Lactobacillus bulgaricus primarily help in the digestion of the milk sugar lactose. Probiotic bacteria in the gut microbiota, primarily, Lactobacillus and Bifidobacterium help in the synthesis of vitamins.
Step-by-step explanation:
Gut Microbiota:
Gut microbiota are the microorganisms that live inside the gastrointestinal tract and aid in various body functions. Also called commensal flora, many of these help in digestion and biosyntheisis of vitamins.
- Lactobacillus species are a predominant component of gut microbiota. Lactobacillus produces an enzyme called lactase that breaks down lactose sugar in milk.
- Complex sugars in vegetables and fruits are broken down, mostly, by gut microbiota.
- Probiotic bacteria, Lactobacillus and Bifidobacterium species aid the biosynthesis of various vitamins and nutrients such as:
- Vitamin K and most of the water‐soluble B vitamins, such as biotin, cobalamin, folates, nicotinic acid, panthotenic acid, pyridoxine, riboflavin, and thiamine.
