IDENTIFICATION OF CADMIUM-ABSORBING STRAIN OF CANDIDA FERMENTATI FROM A POLLUTED AREA IN THE XIANGJIANG RIVER IN XIANGTAN
一株分离于湘江污染水域的酵母(Candida fermentati)的鉴定及其Cd2+的吸附特性

A Cd2+-resistant strain of wild yeast-like fungus in polluted rivers and lakes was isolated in Xiangjiang River near Xiangtan City, named by strain XTWJX. Researches in morphology, physiology, and molecular biology (ITS and 26S rDNA D1/D2) were conducted. Result shows that it belongs to Candida fermentati, could survive in high cadmium concentration of 6.0mmol/L, and could adsorb cadmium in 10mg/L cadmium solution. Therefore, the strain may be applied potentially as a new biomaterials for treatment of cadmium-polluted water.
