**Effect of Different Mineral Nutrients on Invertase Production by Saccharomyces cerevisiae GCB-K5**

Kiran Shafiq, Sikander Ali and Ikram-ul-Haq

The effect of different mineral nutrients was studied on the production of extracellular invertases by Saccharomyces cerevisiae GCB-K5. Nutritional studies were carried out in 250ml Erlenmeyer flasks by submerged fermentation. The culture medium (pH 6.0) was incubated for 48 hours at 30^oC. The optimum levels of peptone and dipotassium hydrogen phosphate were found to be 4.0 and 0.2 g/l, respectively. Maximum invertase activity was found to be 12.68 U/ml. The amount of sugar consumed and dry cell mass were 21.08 and 5.88g/l, respectively.
