Lactobacillus acidophilus ferments glycogen produced by the vaginal epithelium forming ________ ________ resulting in a pH of 4.4 to 4.6 of the vagina and cervix, thus, inhibiting other microorganisms.



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.

Step 3

Lactobacillus acidophilus is a gram-positive bacteria species in the genus Lactobacillus. It is a homofermentative and microaerophilic species. It ferments sugars into lactic acid. It usually grows at relatively low pH values (less than pH 5.0). It requires an optimum growth temperature of about 37 ◦C.  It arises naturally in the animal and human mouth and gastrointestinal tract. It is a part...
