Abstract
Photosynthetic bacteria consortium was isolated from sediment of black odorous river and was named HJ-1. The main pigments were bacteriochlorophyll a and carotenoid. Fructose, mannosej, ethanol, sorbitol, and sodium acetate could be used as carbon source. 16S rDNA gene sequence analysis showed that the dominant strains were Rhodovulum strictum and Thiococcus pfennigii. Its organics-degrading capability was tested using low COD soybean wastewater, low COD brewery wastewater, low COD sugar wastewater and municipal wastewater. Results showed that the COD in all wastewater reached under 100 mg/L within 72 h. COD removal and biomass accumulation were realized. This study suggested the feasibility of COD degradation and resource recovery by HJ-1 in low COD wastewater.
