Abstract excerpt

Mutants of Pichia stipitis NRRL Y-7124 able to tolerate and produce ethanol from hardwood spent sulfite liquor (HW SSL) were obtained by UV mutagenesis. P. stipitis cells were subjected to three successive rounds of UV mutagenesis, each followed by screening first on HW SSL gradient plates and then in diluted liquid HW SSL. Six third generation mutants with greater tolerance to HW SSL as compared to the wild type...
