Minimal transcriptional regulation of horizontally transferred photosynthesis genes in phototrophic bacterium .

Unlabelled: The first phototrophic member of the bacterial phylum , AP64, received all its photosynthesis genes via distant horizontal gene transfer from a purple bacterium. Here, we investigated how these acquired genes, which are tightly controlled by oxygen and light in the ancestor, are integrated into the regulatory system of its new host. grew well under aerobic and semiaerobic conditions, with almost no difference in gene expression.

The Influence of Calcium on the Growth, Morphology and Gene Regulation in .

The bacterium AP64 isolated from a freshwater lake in the western Gobi Desert represents the first phototrophic member of the bacterial phylum Gemmatimonadota. This strain was originally cultured on agar plates because it did not grow in liquid medium. In contrast, the closely related species TET16 grows both on solid and in liquid media.

sp. nov., a Moderately Thermophilic Aerobic Anoxygenic Phototrophic Bacterium Isolated from the Mat Community of an Alkaline Siliceous Hot Spring in Yellowstone National Park, WY, USA.

Strain MS-P2 was isolated from microbial mats associated with Mushroom Spring, an alkaline siliceous hot spring in Yellowstone National Park, WY, USA. The isolate grows chemoheterotrophically by oxygen-dependent respiration, and light stimulates photoheterotrophic growth under strictly oxic conditions. Strain MS-P2 synthesizes bacteriochlorophyll and the carotenoid spirilloxanthin.

Genomic and Phenotypic Characterization of Isolates Provides Evidence for Multiple Species.

is the first and until now the sole genus in the phylum (formerly ) whose members perform chlorophyll-dependent phototrophy (i.e., chlorophototrophy).

sp. nov., an amylase-producing bacterium of the family isolated from marine water in India.

A novel Gram-stain-negative, curved rod-shaped, 0.5-0.7 µm wide and 3.

Draft Genome Sequence of a Filamentous Anoxygenic Phototrophic Bacterium, " Roseilinea sp. Strain NK_OTU-006," Recovered from Metagenomic Data of a Hot Spring Microbial Mat.

We report here the metagenome-assembled draft genome of an uncultured filamentous anoxygenic phototroph of the phylum (formerly ), " Roseilinea sp. strain NK_OTU-006," recovered from hot spring-associated microbial mats. The 3.

gen. nov., sp. nov., a novel thermophilic phototrophic purple sulphur bacterium of the isolated from Nakabusa hot springs, Japan.

A novel thermophilic phototrophic purple sulphur bacterium was isolated from microbial mats (56 °C) at Nakabusa hot springs, Nagano prefecture, Japan. Cells were motile, rod-shaped, stain Gram-negative and stored sulphur globules intracellularly. Bacteriochlorophyll and carotenoids of the normal spirilloxanthin series were the major pigments.

Shewanella submarina sp. nov., a gammaproteobacterium isolated from marine water.

A curved-rod-shaped bacterium was isolated from a marine (100 m depth) water sample collected from Bay of Bengal, Visakhapatnam, India. Strain NIO-S14, was Gram-stain-negative, motile and pale-yellow. NIO-S14 was able to grow aerobically and anaerobically and could utilize a number of organic substrates.

Imhoffiella gen. nov., a marine phototrophic member of the family Chromatiaceae including the description of Imhoffiella purpurea sp. nov. and the reclassification of Thiorhodococcus bheemlicus Anil Kumar et al. 2007 as Imhoffiella bheemlica comb. nov.

A coccoid-shaped phototrophic purple sulfur bacterium, strain AK35T, was isolated from a coastal surface water sample collected from Visakhapatnam, India. Cells were Gram-stain-negative, motile and purple, containing bacteriochlorophyll a and the carotenoid rhodopinal as major photosynthetic pigments. Strain AK35T was able to grow photoheterotrophically and could utilize a number of organic substrates.
