Improvement of ethanol production by extractive fed-batch fermentation in a drop column bioreactor.

abstract：:Candida cylindracea NRRL Y-17506 was grown to produce extracellular lipase from oleic acid as a carbon source. Through flask cultures, it was found that the optimum initial oleic acid concentration for cell growth was 20 g l(-1). However, high initial concentrations of oleic acid up to 50 g l(-1) were not inhibitory. ...
