Raw starch degrading amylase production by mixed culture of Aspergillus niger and Saccharomyces cerevisae grown on sorghum pomace

Production of raw starch degrading amylase by a mixed culture of Aspergillus niger and Saccharomyces cerevisae grown on sorghum pomace as nutrient source was investigated. Effect of mineral nutrient supplementation of sorghum pomace on raw starch degrading amylase activity was also determined.
