Glygerol production under solute stress using the mixed culture of trichoderma viride and saccharomyces cerevisiae Y-1347

ABSTRACT

The effect of salt stress on the growth parameters of S.cerevisiae Y-1347 was studied by using Nacl. The increase in Nacl level was accompanied by a parallel increase in the efficiency of the cultures to convert glucose to glycerol. Maximum glycerol and glycerol phosphate dehydrogenase production [700 mg/l00ml and 198 U/ml respectively] were achieved with 5.8 g% Nacl 3% [W/V] NaHSO[3] and 1 g/l beef extract in presence of tween 80 with a[w] = 0.24k[-1]
