Transformation of monothioarsenate by haloalkaliphilic, anoxygenic photosynthetic purple sulfur bacteria [PDF]

FEMS Microbiology Ecology, 2014
Thioarsenates are the dominant arsenic species in arsenic-rich, alkaline, and sulfidic waters, but bacterial interactions with these compounds have only recently been examined. Previous studies have shown that microorganisms play a role in the transformation of monothioarsenate to arsenate, including use of monothioarsenate as a chemolithotrophic ...

Identification and properties of the purple photosynthetic sulfur bacteria of genus Thiorhodococcus isolated from Saki lake (AR Crimea)

Біологічні студії, 2012
The phototrophic bacteria were isolated from water and silt of Saki lake (AR Crimea). The were brown-red coloured. This bacteria used hydrogen sulfide in anaerobic photosyntetical process and stored elemental sulfur inside the cells.

Purple non-sulfur bacteria for biotechnological applications

Journal of Industrial Microbiology and Biotechnology
Abstract   In this review, we focus on how purple non-sulfur bacteria can be leveraged for sustainable bioproduction to support the circular economy. We discuss the state of the field with respect to the use of purple bacteria for energy production, their role in wastewater treatment, as a fertilizer,

The Effects of Roundup™ on Benthic Microbial Assemblages

Ecologies, 2022
Given the wide usage of Roundup, a common herbicide, the impacts of its presence in ecological communities are of great interest. Many studies have investigated the effects of glyphosate, the active ingredient in Roundup, on different factions of an ...

Phylogenetic analysis of a microbialite-forming microbial mat from a hypersaline lake of the Kiritimati atoll, Central Pacific.

PLoS ONE, 2013
On the Kiritimati atoll, several lakes exhibit microbial mat-formation under different hydrochemical conditions. Some of these lakes trigger microbialite formation such as Lake 21, which is an evaporitic, hypersaline lake (salinity of approximately 170‰).

Fifty years of limnology (1969-2019) at Mahoney Lake, British Columbia, Canada

Limnological Review, 2020
Mahoney Lake is a small, meromictic saline lake in south-central British Columbia noted for its unique layer of purple sulfur bacteria. First examined in 1969, this lake has undergone physical, chemical, biological, and pre-historical research to ...
