Iron mycobacteria smegmatis
WebApr 22, 2011 · Mycobacterium smegmatis is a Gram-positive bacteria, characterized by an inner cell membrane and a thick cell wall. The Gram-positive bacteria is further classified as one with a high GC content and therefore a low AT content. This quality is used as a crude measure of similarity of different species of bacteria. WebFirst, in the growth environment at pH 6–8, the cell surface is hydrolyzed by iron bacteria, affording negatively charged groups such as OH − and COO −, which make the cell …
