Question

The strain used to identify bacteria with a large amount of peptidoglycan in their cell walls is the:

A) Gram-negative strain
B) Gram-positive strain
C) Acid-fast strain
D) Capsulated strain

Answer 1

The strain used to identify bacteria with a large amount of peptidoglycan in their cell walls is the Gram-positive strain.

Step-by-step explanation:

The strain used to identify bacteria with a large amount of peptidoglycan in their cell walls is the Gram-positive strain.

Gram-positive bacteria have a thick cell wall consisting of many layers of peptidoglycan, which differentiates them from Gram-negative bacteria.

The peptidoglycan layers in Gram-positive bacteria are also commonly embedded with teichoic acids (TAs), which stabilize the peptidoglycan and play a role in bacterial infection.
