The goal of this research was to implement a microbiological method to reduce the concentrations of chromium (VI) of sewage sludge from tanneries through the combination of processes of environmental engineering and microbiology. A system of fixed medium was used, it contained a plastic support to which the lama of microorganisms adheres, performing the purification process under controlled physical conditions, this is demonstrated in vivo with measurements of chromium VI by atomic absorption of treated effluent and in vitro by isolation and identification of microorganisms in selective culture media with K2CrO4. The results show a 58% Cr (VI) reduction of the microorganisms: Bacillus cereus, Acinetobacter iwoffi, Lactobacillus agilis, Penicillium sp. and Cladosporium sp. Which are able to tolerate Cr (VI) concentrations of 300 ppm.
