A novel chloride-tolerant bacterial strain (bacillus firmus strain S616) isolated from the activated sludge of the wastewater treatment system of a diosegenin production plant
In an effort to find halophilic bacteria capable of biologically degrading refractory organics in saline diosgenin wastewaters with high COD concentrations, a calcium chloride tolerant bacterial strain(numbered as S616 by the authors) was successfully isolated. Its 16S rDNA sequence is closely related to Bacillus firmus by a 98.0-99.0％ similarity. Detailed studies on COD of Diosgenin wastewater removal efficiencies of the strain S616 indicate that COD removal efficiency was up to about 80％ when degradation time, pH, temperature,and inoculation were 48 h, 7-8, 30-35℃ and 1 ml, respectively, which offers the theoretical basis for the bacterial strain to be used in treating high chloride wastewaters.
