[Acidophilic thermotolerant Candida utilis yeast strain obtained by continuous cultivation]

An acidophilic thermotolerant strain of Candida utilis 1668-3-37 was produced under conditions of continuous cultivation during 128 days. The optimum pH is 3.0-4.5 at 32 degrees C. The strain grows with mumax=0.30 hr(-1) at 37-38 degrees C and the same pH values if dry yeast autolysate (0.05%) is added to the medium.
