Isolation and characterization of selenate resistant mutants of Acremonium chrysogenum
Brazilian Archives of Biology and Technology, 1999 Mutants unable to convert exogenous sulfate to sulfite were isolated using the toxic analogue selenate. Three of twenty-eight isolated mutants were chromate sensitive. They showed a possible lesion in the gene that codes the ATP sulfurylase.
