Removal of Chromate by White Rot Fungus, Inonotus cuticularis

A chromate-resistant white rot fungus, Inonotus cuticularis, abundant in oak trees, was isolated for chromate removal and detoxification of chromate. Inonotus cuticularis was also investigated for an optimal waste treatment system. The screened cells were able to reduce an initial chromate concentration of as high as 1,300ppm. Cell growth kinetics showed that the optimum culture conditions in flasks were at 33℃ and pH 4.2. furthermore, the cells were able to remove 54% of the initial chromate by a two-stage operation based on the combination of a fermentor and airlift reactor.
