sp. nov.-A Novel Halophilic Alkalitolerant Bacterium Capable of Polyol Degradation: Physiological Properties and Genomic Insights.

A search for the microorganisms responsible for the anaerobic degradation of osmoprotectants in soda lakes resulted in the isolation of a novel halophilic and alkalitolerant strain, designated Z-7514. The cells were Gram-stain-negative and non-endospore-forming rods. Optimal growth occurs at 1.

Halonatronomonas betaini gen. nov., sp. nov., a haloalkaliphilic isolate from soda lake capable of betaine degradation and proposal of Halarsenatibacteraceae fam. nov. and Halothermotrichaceae fam. nov. within the order Halanaerobiales.

A search for the organisms responsible for anaerobic betaine degradation in soda lakes resulted in isolation of a novel bacterial strain, designated Z-7014. The cells were Gram-stain-negative, non-endospore-forming rods. Growth occurred at 8-52 °C (optimum 40-45 °C), pH 7.

Lithoautotrophic lifestyle of the widespread genus Roseovarius revealed by physiological and genomic characterization of Roseovarius autotrophicus sp. nov.

The genus Roseovarius, a member of the ecologically important Roseobacter-clade, is widespread throughout the world. A facultatively anaerobic lithoautotrophic bacterium (strain SHN287T), belonging to the genus Roseovarius, was isolated with molecular hydrogen as an electron donor and nitrate as an electron acceptor from a terrestrial mud volcano. Strain SHN287T possessed metabolic features not reported for Roseovarius such as chemolithoautotrophic growth with oxidation of molecular hydrogen or sulfur compounds, anaerobic growth and denitrification.

gen. nov., sp. nov., a novel haloalkaliphile isolated from a laboratory culture cyanobacterium species and proposals of fam. nov., fam. nov., ord. nov. and ord. nov.

A prosthecate bacterial strain, designated G-192, was isolated from decaying biomass of a haloalkaliphilic cyanobacterium sp. Z-T0701. The cells were aerobic, Gram-negative, non-endospore-forming and dimorphic, occurring either as sessile bacteria with a characteristic stalk or as motile flagellated cells.
