Sorokin, Dimitry Y. (author), Kolganova, Tatiana V. (author), Khijniak, Tatiana V. (author), Jones, Brian E. (author), Kublanov, Ilya V. (author)Alkaline saline soils, known also as ''soda solonchaks'', represent a natural soda habitat which differs from soda lake sediments by higher aeration and lower humidity. The microbiology of soda soils, in contrast to the more intensively studied soda lakes, remains poorly explored. In this work we investigate the diversity of culturable...journal article 2017

Sorokin, Dimitry Y. (author), Kublanov, Ilya V. (author), Khijniak, Tatiana V. (author)Brine samples from Kulunda Steppe soda lakes (Altai, Russia) were inoculated into a hypersaline alkaline mineral medium with β-keratin (chicken feather) as a substrate. The micro-organisms dominating the enrichment culture were isolated by limiting serial dilution on the same medium with casein as a substrate. The cells of strain BSker1<sup>T...journal article 2017

Sorokin, Dimitry Y. (author), Chernyh, N. A. (author)Propionate can be directly oxidized anaerobically with sulfate as e-acceptor at haloalkaline conditions either incompletely to acetate (an example is Desulfobulbus alkaliphilus), or completely (for example by the members of genus Desulfonatronobacter). An enrichment with propionate at methanogenic conditions (without sulfate) inoculated with...journal article 2016

(author)Haloalkaliphilic microorganisms that grow optimally at high-pH and high-salinity conditions can be found in natural environments such as soda lakes. These globally spread lakes harbour interesting anaerobic microorganisms that have the potential of being applied in existing technologies or create new opportunities. In this review, we discuss...review 2015
