26 Jan 2018 We present a method for the microfluidic analysis of individual bacterial cell lineages using Bacillus subtilis as an example.

The resulting collective morphology is consequently appropriate for a particu-lar environment. Bacillus subtilis (B. subtilis), a Gram-positive model bacterium in biofilm research, is able to form morphologically complex and exceptionally robust colony-type biofilm . This bacterium is considered to be largely non-pathogenic, although it has been linked to food spoilage [ 7 , 8 ]. Routine microscopic examination of B. subtilis cultures revealed t hat strains bearing gtaC and gtaE mutations had apparently normal cell morphology on LB agar plates (Fig. (Fig.4A).

Here we study the formation of macroscopic structures (wrinkles and folds) observed during the maturation of Bacillus subtilis pellicles in relation to their mechanical response. Bacillus subtilis is considered a soil organism for which endospore formation provides a means to ensure long-term survival in the environment. We have addressed here the question of what happens to a spore when ingested.

Bacillus subtilis, known also as the hay bacillus or grass bacillus, is a Gram-positive, catalase -positive bacterium, found in soil and the gastrointestinal tract of ruminants and humans. A member of the genus Bacillus, B. subtilis is rod-shaped, and can form a tough, protective endospore, allowing it to tolerate extreme environmental conditions.

The Bacillus subtilis tag-1mutation has been transferred into five different strains to determine the effect of genetic background on the expression of a gene regulating cell morphology. Two patterns of expression at restrictive temperature were observed: 1. Irregular, unstable spherical cells unable to form colonies. Abstract Biofilms are commonly defined as accumulations of microbes, embedded in a self-secreted, polysaccharide-rich extra-cellular matrix. This study aimed to characterize specific morphological changes that occur in Bacillus subtilis biofilms under nutrient-limiting growth conditions. Description of a colony's morphology includes its shape, the margins or edges of the colony, its color, and surface features. Some colonies are round and smooth, others can have wavy edges and a wrinkled appearance.
