Abstract
The by – products of corn starch industry were used for preparation of media to propagate some fungi , and these were corn steep water (S) and gluten after extraction of soluble fraction (G) . These by – products were used after suitable treatments , and used to prepare mixed medium (GS) . The by – products contain most of the essential requirements for fungal growth . They have been used to cultivate Aspergillus niger , Asp. flavus , Penicillium spp and the yeast Saccharomyces boulardii . The growth was recorded by measuring the colony diameter for moulds grown on solid media and biomass for liquid media . For yeast the viable count was determined , all these measurements were run in comparison to Sabouraud media (Oxoid ) as a standard medium .The results indicated that the GS solid medium was superior to support the fungal growth , followed by (S) medium . then the standard medium , and finally the gluten medium with significant statistical differences (P<0.05) for the three moulds . Growth in liquid media (Biomass) showed that steep water medium (S) was the best to support the growth. Shaked cultures gave higher biomass and differ from static cultures significantly (P<0.05) . Growth of S . boulardii in liquid media was better in shaked cultures than static cultures with significant differences (P<0.05) for different media .
