“…oxidation of the H # S produced by organo-and lithotrophic, haloalkaliphilic, sulfate-reducing bacteria, a poorly studied functional group of the trophic network (Zhilina & Zavarzin, 1994). Only one bacterium representing this group of lithotrophic organisms, Desulfonatronovibrio hydrogenovorans, has to date been isolated in pure culture from Lake Magadi sediments (Zhilina et al, 1997).

Alcalilimnicola halodurans gen. nov., sp. nov., an alkaliphilic, moderately halophilic and extremely halotolerant bacterium, isolated from sediments of soda-depositing Lake Natron, East Africa Rift Valley An alkaliphilic, halotolerant, Gram-negative, heterotrophic, aerobic and rodshaped organism was isolated from drying soda and at a water-covered site of Lake Natron, Tanzania, by means of the most-probable-number technique developed for anoxygenic, phototrophic sulfur bacteria. It had an absolute requirement for alkalinity, but not for salinity ; growth occurred at salt concentrations of 0-28 % (w/v), with optimal growth at 3-8 % (w/v) NaCl. The bacterium preferentially metabolized volatile fatty acids and required vitamins for growth. The name Alcalilimnicola halodurans gen. nov., sp. nov. is proposed for the novel isolate, placed in the γ-Proteobacteria within the family Ectothiorhodospiraceae on the basis of analysis of the 16S rDNA sequence, polar lipids, fatty acids and DNA base composition. Although Alcalilimnicola halodurans is closely related to the extreme anoxygenic, phototrophic sulfur bacteria of the genus Halorhodospira, it is not phototrophic.

A novel alkaliphilic, sulfate-reducing bacterium, strain MLF1 T , was isolated from sediments of soda Mono Lake, California. Gram-negative vibrio-shaped cells were observed, which were 0?6-0?761?2-2?7 mm in size, motile by a single polar flagellum and occurred singly, in pairs or as short spirilla. Growth was observed at 15-48 6C (optimum, 37 6C), >1-7 % NaCl, w/v (optimum, 3 %) and pH 8?0-10?0 (optimum, 9?5). The novel isolate is strictly alkaliphilic, requires a high concentration of carbonate in the growth medium and is obligately anaerobic and catalasenegative. As electron donors, strain MLF1 T uses hydrogen, formate and ethanol. Sulfate, sulfite and thiosulfate (but not sulfur or nitrate) can be used as electron acceptors. The novel isolate is a lithoheterotroph and a facultative lithoautotroph that is able to grow on hydrogen without an organic source of carbon. Strain MLF1 T is resistant to kanamycin and gentamicin, but sensitive to chloramphenicol and tetracycline. The DNA G+C content is 63?0 mol% (HPLC). DNA-DNA hybridization with the most closely related species, Desulfonatronum lacustre Z-7951 T , exhibited 51 % homology. Also, the genome size (1?6610 9 Da) and T m value of the genomic DNA (71±2 6C) for strain MLF1 T were significantly different from the genome size (2?1610 9 Da) and T m value (63±2 6C) for Desulfonatronum lacustre Z-7951 T . On the basis of physiological and molecular properties, the isolate was considered to be a novel species of the genus Desulfonatronum, for which the name Desulfonatronum thiodismutans sp. nov. is proposed (the type strain is MLF1 T
