Bioreduction of Cr (VI)to less toxic and less mobile Cr(lII)is considered to be a viable clean up option.Cr(VI) bioreduction also produces soluble Cr(IlI)-organic complexes with insoluble Cr(IlI)compounds.Though little is known about the fate and behaviour of soluble Cr-Ⅲ-organic in the environment,it is reported that once Cr-(III)-organic complexes are formed,they are relatively stable,due to the slow ligand exchange properties of Cr(III).There is no reported data about the toxicity of the Cr-(III)-organic complexes.The aim of this current research is to investigate the bioavailability and toxicity of the soluble Cr-III-organic complexes.For the experimental purpose Saccharomyces cereviciae L-1 wild type yeast strain was chosen as model organism and Cr-Ⅲ-citrate was selected as the representative compound of the Cr-(Ⅲ)-organic complexes.Growth inhibition,direct viable cell count,dry biomass,biosorption as well as the amount of CO2 production were measured to explore the potential for short-term chronic aquatic toxicity tests of the Cr-(Ⅲ)-citrate.Cr-(Ⅲ)-citrate exerted the tOxicity with an EC50,calculated from the%growth inhibition,of 51.03 mg/L.These toxicity data would be helpful to define the toxic potential of the organo-chromium-III compounds in the environment.
