-glutamyl-transpeptidase, which ensures the protective layer stays attached.
Several studies have investigated the effects of Poly-D-Glutamic Acid on human health: poly d glutamic acid capsule
-PGA) is a naturally occurring, water-soluble, biodegradable, and non-toxic polymer composed of repeated units of the amino acid D-glutamic acid. Unlike the L-amino acids standard in human protein production, the D-isoform used by B. anthracis is resistant to the proteolytic enzymes of the host immune system. poly d glutamic acid capsule
The capsule can be visualized in laboratory settings using special staining techniques, such as India ink staining (where it appears as a clear halo) or M'Fadyean’s polychrome methylene blue staining (where the capsule stains pink).
