أمثلة ظروف إنتاج الكتلة الحيوية لخميرة Saccharomyces cerevisiae المدعمة السيلينيوم

Abstract EN

This research was conducted in 2015, at the Food Science Department laboratories, Faculty of Agriculture-Damascus University.

Selenium enriched yeast, produced by growing of Saccharomyces cerevisiae in molasses medium (12%) and the culture conditions of production including initial sodium selenite concentration(15-22.5-30 µg/mL), initial pH(3-4-5) and incubation temperature (30-31.5-33°C) were optimized using Response surface methodology (RSM).

The results showed that the optimum conditions for production of selenium enriched were achieved on molasses medium containing 22.5 µg/mL(Na2SeO3) with an initial pH of 4 at 31.5°C , these optimum conditions generated (2.3010 g/L) of the biomass yield, and the total selenium-accumulation in the range of(0 -29900 ppm).
