Ammonium removal from wastewaters has recently became a major concern of fertilizer manufacturers and industrial zones in Vietnam. Using aerobic ammonium remover may be a appreciate solution for reduction of treatment cost. This study describes the isolation and characterization of a novel bacterium for ammonium removal under aerobic conditions. Twelve ammonium remover strains were isolated from wastewater of a local fertilizer industry. The isolated strains were initially screened using solid media for their nitrifying activities. Among them two of the bacteria displayed the highest removal of ammonium without much accumulation of nitrite and nitrate. The isolates were identified as Acinetobacter based on biochemical characteristis and 16S rRNA sequence. One of these two isolates, Acinetobacter calcoaceticus A8 strain, showed 88% ammonium removal from industrial fertilizer wastewater.

The analysis of three water samples from two cooling towers and one river allowed us to isolate three strains of a novel species of the class Alphaproteobacteria which is phylogenetically related to uncultured alphaproteobacteria. Based upon 16S rRNA gene sequence analysis and phenotypic characterization, we propose to name this novel species Reyranella massiliensis gen. nov., sp. nov., type strain 521T ( = CSUR P115T  = DSM 23428T). The most closely related cultivable micro-organism to this novel bacterium is a member of the genus Magnetospirillum.

Insight Into

ABSTRACT Two membrane-bound, reductive dehalogenases that constitute a novel pathway for complete dechlorination of tetrachloroethene (perchloroethylene [PCE]) to ethene were partially purified from an anaerobic microbial enrichment culture containing Dehalococcoides ethenogenes 195. When titanium(III) citrate and methyl viologen were used as reductants, PCE-reductive dehalogenase (PCE-RDase) (51 kDa) dechlorinated PCE to trichloroethene (TCE) at a rate of 20 μmol/min/mg of protein. TCE-reductive dehalogenase (TCE-RDase) (61 kDa) dechlorinated TCE to ethene. TCE,cis-1,2-dichloroethene, and 1,1-dichloroethene were dechlorinated at similar rates, 8 to 12 μmol/min/mg of protein. Vinyl chloride and trans-1,2-dichloroethene were degraded at rates which were approximately 2 orders of magnitude lower. The light-reversible inhibition of TCE-RDase by iodopropane and the light-reversible inhibition of PCE-RDase by iodoethane suggest that both of these dehalogenases contain Co(I) corrinoid cofactors. Isolation and characterization of these novel bacterial enzymes provided further insight into the catalytic mechanisms of biological reductive dehalogenation.
