Abstract

Sulfide is an inorganic of sulfur, which is the least oxidation. It can be oxidized by oxygen in the air or by microorganisms. The presense of sulfide in waste results in rotten egg odor, which greatly impact the environment and living organisms. The BNS4 strain has the ability to oxidize sulfur was isolated from mud from waste lakes such as Nam Son, Soc Son district, Hanoi. Based on colony appearance as well as the DNA sequence of 16S rRNA, the BNS4 strain is 99% similar to the Alcaligenes then it was called as Alcaligenes sp. BNS4. The optimal conditions for growing and oxidizing of the strain were at pH 7 with thiosulfate (S2O32-) concentration at 12 mM. The oxidation of thiosulfate (S2O32-) was calculated based on the measurement of SO42-in the environment at 582.9 mg/l. These results indicated that the Alcaligenes sp. BNS4 helps to increase the diversity of the sulfide and organic processing species in the air and water waste.
