Abstract
Saccharomyces cerevisiae (CCT(-)3174 and commercial baker's yeast) was immobilized by adsorption onto chrysotile. The adsorbed yeast cells w ere easily washed out, but cells grown in situ were strongly attached by entrapment by chrysotile microfibres. In fermentation experiments w ith 30% (w/v) glucose solution, the immobilized cells showed a 1.3-fol d increase in initial reaction velocity. For immobilized CCT 3174, the final ethanol yield was 26% higher than that with free cells. (C) 199 8 Society of Chemical Industry.
