Expert Answer

Step 1

The question asks to fill the following blank:

Lactobacillus acidophilus ferments the glycogen that is produced by the vaginal epithelium and forms  ______ _______ due to which resulting pH is 4.4 to 4.6 of the vagina and cervix, thus, it inhibits the other microorganisms.

Step 2

Fermentation can be defined as the chemical degradation of a substance by yeasts, bacteria, or another microorganism. It usually involves aeration and release of heat.

Homofermentative is a characteristic by which an organism produces fermentation that has a single end product. It uses an economically significant lactic-acid bacteria which ferment the carbohydrates to lactic acid.

Microaerophilic species is a microorganism that requires very little oxygen at a lower partial pressure than that of atmospheric oxygen.
