摘要: Hypersaline, alkaline (>pH 9) lakes constitute a special class of extremely saline in closed basins. The major ions are typically Na+, Cl-, HCO 3 - and CO 2- . Sulfate is proportionately low. high concentrations largely responsible for buffering these at such pH. From both biological geochemical viewpoints, hypersaline, the African Rift Valley best known. Unfortunately, much literature describing situ activity those their sediments concerns less region (Tailing et al., 1973; Hammer, 1981; Melack, 1981). However, reports isolation bacteria involved reductive part sulfur cycle more Africa may support theory that microorganisms can play role development conditions
