Formation of unique T-shape budding and differential impacts of low surface water on Bacillus mycoides rhizoidal colony.

Bacillus mycoides Ko01 strain grows rapidly and forms extensive rhizoidal colonies on hard agar despite limited surface water availability. The agar concentrations affect the handedness of the colonies as well as other colony architectures. In this study, we found that the local curvature of cell chains in the developing colonies did not vary based on the agar concentration, while concentration does affect the handedness of chirality at the macroscale.

Cellular Memory of HipA-Induced Growth Arrest: The Length of Cell Growth Arrest Becomes Shorter for Each Successive Induction.

Toxin-antitoxin (TA) systems are genetic modules found commonly in bacterial genomes. HipA is a toxin protein encoded from the TA system in the genome of Ectopic expression of induces cell growth arrest. Unlike the cell growth arrest caused by other TA toxins, cells resume growth from the HipA-induced cell growth arrest phase after a defined period of time.

Comparative Proteomic Analysis of Propane Metabolism in Mycobacterium sp. Strain ENV421 and Rhodococcus sp. Strain ENV425.

While growing on propane as a sole source of carbon, many strains cometabolically degrade environmental pollutants, such as ethers and chlorinated hydrocarbons. To gain insights into the molecular basis behind such a high metabolic versatility of propanotrophs, we examined the propane-inducible protein expression patterns of 2 soil actinobacteria that are known to degrade a variety of ethers (i.e.

Genomic Analysis of Propane Metabolism in Methyl -Butyl Ether-Degrading Sp. Strain ENV421.

Methyl -butyl ether (MTBE) is a ground water contaminant with plausible carcinogenic properties. sp. strain ENV421 cometabolically degrades MTBE and other ethers during the growth on propane as a carbon source.

Draft Genome Sequence of a Propanotroph, Rhodococcus sp. Strain ENV425, Capable of Degrading Methyl -Butyl Ether and -Nitrosodimethylamine.

In this study, the draft genome of sp. strain ENV425 was determined. The propane-grown strain ENV425 cometabolically degrades environmental contaminants such as methyl -butyl ether and -nitrosodimethylamine.
