Effect of nitrogen sources on the production of invertase by yeast saccharomyces cerevisiae 3090.

Invertase from Saccharomyces cerevisiae is high cost enzyme and primarily used in the confectionary industry. For large scale production of the enzyme, feasible synthetic medium with appropriate supplemented nutrients are required. The effect of carbon source on invertase production is well known, but little is known about the effect of different nitrogen source. The aim of the present study is to see the effect of different nitrogen sources on the production of invertase in submerged fermentation by Saccharomyces cerevisiae. It was found that when urea as nitrogen source is added in a little amount to the fermentation medium it showed a marked increase in Invertase production.
