Importance of medium pH in solid state fermentation for growth of Schwanniomyces castellii

Utilization of soluble starch by Schwanniomyces castellii in a solid state fermentation system was highest in unbuffered medium when initial and final pH of the medium were 6.5–7.0 and 4.0–4.6, respectively. An economic strategy involving the use of urea as a sole nitrogen source in medium with init...

Description
Summary:Utilization of soluble starch by Schwanniomyces castellii in a solid state fermentation system was highest in unbuffered medium when initial and final pH of the medium were 6.5–7.0 and 4.0–4.6, respectively. An economic strategy involving the use of urea as a sole nitrogen source in medium with initial pH of 6.5 allowed maximum substrate utilization in the absence of buffer and without any contamination in column fermenter.
