Study on microbial diversity of washing machines.

Health and environmental protection are the development trend of household appliances, coupled with the impact of the COVID-19 epidemic in the past few years. Consumers have unprecedented concerns and expectations about the sterilization and disinfection functions of household appliances. As a washing and nursing equipment for household clothes, the anti-bacterial technology of washing machine has developed rapidly.

Mechanism of TonB-dependent transport system in Halomonas alkalicola CICC 11012s in response to alkaline stress.

Halomonas alkalicola CICC 11012s can grow at pH 12.5, the highest pH at which the organisms in the genus Halomonas can grow. Genomic analysis reveals that H.

sp. nov., isolated from yellow water of strongly flavored Chinese baijiu.

A Gram-stain-positive, strictly aerobic and rod-shaped bacterium, designated as 3 H-10, was isolated from a yellow water sample collected from the manufacturing process of strong flavor Chinese baijiu in Yibin region of Sichuan province (PR China). Oval endospores were formed at the subtermini of cells with swollen sporangia. The isolate was able to grow at temperatures of 20-45 °C (optimum growth at 37 °C), at pH 6.

Paenibacillus maysiensis sp. nov., a Nitrogen-Fixing Species Isolated from the Rhizosphere Soil of Maize.

A novel bacterium SX-49 with nitrogen-fixing capability was isolated from the rhizosphere soil of maize. Phylogenetic analysis of nifH gene fragment and 16S rRNA gene sequence revealed that the strain SX-49 is a member of the genus Paenibacillus. Values of 16S rRNA gene sequence similarity were highest between SX-49 and P.

Genome sequencing and heterologous expression of antiporters reveal alkaline response mechanisms of Halomonas alkalicola.

Halomonas alkalicola CICC 11012s is an alkaliphilic and halotolerant bacterium isolated from a soap-making tank (pH > 10) from a household-product plant. This strain can propagate at pH 12.5, which is fatal to most bacteria.

Comparative genomic analysis of N2-fixing and non-N2-fixing Paenibacillus spp.: organization, evolution and expression of the nitrogen fixation genes.

We provide here a comparative genome analysis of 31 strains within the genus Paenibacillus including 11 new genomic sequences of N2-fixing strains. The heterogeneity of the 31 genomes (15 N2-fixing and 16 non-N2-fixing Paenibacillus strains) was reflected in the large size of the shell genome, which makes up approximately 65.2% of the genes in pan genome.
