Medium optimization for biomass production and protien content of candida utilis k50

الملخص EN

Molasses medium containing different concentrations of (NH4)2 S04, (NH4)3 P04, urea, KCI, and P205 were compared with the medium used for commercial production of C.

utitis in a factory south of Iraq.

An efficient medium, which produced 19.16 % dry wt, and 5.

78 % protein, was developed.

The effect of adding various concentrations of micronutrients (FeS04, 7T20, IvInS04, 7H20, ZnS04.

7H20) was also studied.

Results showed that FeSo4.

7H20 caused a noticeable increase in both dry wt.

and protein content of the yeast.
