Mycobacteria are Gram-positive, catalase positive, non-motile, non-spore forming rod-shaped bacteria (0.2–0.6 μm wide and 1.0–10 μm long). Mycobacterium tuberculosis ESAT-6 (MtbESAT-6) plays essential roles in pathogenesis. Compared to M. tuberculosis, M. smegmatis is a fast-growing organism and belongs to hazard group 2. Lactobacillus spp. It is possible that the spore-forming streptomyces also do this, although the generation of spores in aerial hyphae is quite different, since multiple septa are generated at once along a long hyphal branch (135, 369). Mycobacteria are Gram-positive, catalase positive, non-motile, non-spore forming rod-shaped bacteria (0.2–0.6 μm wide and 1.0–10 μm long). Streptomyces coelicolor, a gram-positive, sporulating bacterium, is phylogenetically a close relative of Mycobacterium tuberculosis, with a similarly high GC content (65 to 70%).This organism follows a differentiation cycle in which young colonies send hyphal extensions into the agar and later-generation cells form white aerial hyphae which become pigmented and produce spores (). Activity Mycobacteria, along with exospore forming Streptomyces, belong to the phylum actinobacteria. Some evidence suggests that cells survive in nutrient-deprived stationary phase.
