Nitrogen Fixation Activity and Genome Analysis of a Moderately Haloalkaliphilic Anoxygenic Phototrophic Bacterium .

The genome of the moderately haloalkaliphilic diazotrophic anoxygenic phototrophic bacterium A-36s isolated from an alkaline lake was analyzed and compared to the genomes of the closest species A-20s and DSM 11289. The genomic features of three organisms are quite similar, reflecting their ecological and physiological role of facultative photoheterotrophs. Nevertheless, the nitrogenase activity of the pure cultures of the studied bacteria differed significantly: the highest rate (4066 nmoles CH/mg of dry weight per hour) was demonstrated by while the rates in and were an order of magnitude lower (278 and 523 nmoles CH/mg of dry weight per hour, respectively).

AlgalTextile - a new biohybrid material for wastewater treatment.

Efficient nutrient extraction from wastewater and reuse as bio-fertilizer is an important task for reducing anthropogenic load toward circular economy. Inspired by microbial mats and biofilms, we developed a new material AlgalTextile (AT) that effectively absorbs nutrients from a medium. AT consists of three fully organic components: microalgae, alginate and textile.

Draft Genome Sequence of the Anoxygenic Phototrophic Bacterium sp. Strain U11-2br, Isolated from a Mountain Lake on the Ulagan Plateau.

We report the draft genome sequence of an anoxygenic phototrophic bacterium, sp. strain U11-2br, which was isolated from a freshwater mountain lake on the Ulagan Plateau (Altai, Russia). The assembly contains 4,514,979 bp, with a GC content of 59.

Draft Genome Sequence of the Anoxygenic Phototrophic Bacterium sp. Strain Az07, Isolated from a Brackish Canal.

sp. strain Az07 was isolated from a brackish canal. The organism is more halotolerant than previously described species of the genus .
