Answer 1

Answer:

These bacilli are generally nonmotile, but some species are motile due to peritrichous flagella. They are Gram positive, however, if there are dead bacteria, they stain red, giving a variable Gram image in the presence of Gram staining.

They do not sporulate and some strains have bipolar bodies that probably contain polyphosphate.

Homofermentative Lactobacilli have internal granules revealed by Gram stain or by methylene blue staining.

For the diagnosis and identification of the species, the most useful method is the Polymerase Chain Reaction (PCR).
