Waste liquor from caprolactam manufacture contains many mono- and di-carboxylic acids. Of four yeasts tested, Yarrowia lipolytica DS-1 was the best at decreasing Chemical Oxygen Demand values, by up to 60% with 50 and 100 g waste liquor/after 48 h. Caproic, butyric and valeric acids were utilized most easily. Adipic acid was not decreased below 13% (w/v).
