A mature B. subtilis colony is revealed under magnification to be a remarkable assemblage of cooperating cells, with motile cells near the base, sporulating cells at the top, and matrix‐producing chains clustered throughout (Vlamakis et al., 2008).

Colony Morphology Colony morphology gives important clues as to the identity of their constituent microorganisms. Enterobacter aerogenes. The Winner: Bacillus subtilis Colony …

Figures 3(b1){3(b8) show … A Bacillus subtilis colony grows on an agar surface over the course of eight hours. The colony is about a centimeter in diameter.

The organism has been observed to show several colony morphologies including multicellularity has been the bacterial species, Bacillus subtilis, whose cells named BtqEA15_M1, has a very different colony morphology than the wild type. Bacteria grown on agar surfaces can grow into a variety of colony shapes, ranging from a basic circle to Morphological diagram of B. subtilis colony patterns. 2 Mar 2017 Here, we report a morphological change in Bacillus subtilis biofilms due morphology of microbial colony should embody characteristic growth 30 Sep 2014 ABSTRACT.

Morphology.

Bacillus subtilis is a typical germ, gram-positive and rod-shaped. When it is cultured on a usual nutrient agar, the morphology circular colony of these bacteria is opaque, rough, slightly yellow or fuzzy white with jagged edges.

They are approximately 1 micron wide by 2-3 microns long. They are found individually or in small chains. Bacillus subtilis has been one of the principal organisms used for the investigation of genetic transformation.
