Aspergillus oryzae was co-cultured with Trichoderma reesei using acorn cups extract containing up to 62% ellagitannins as substrate to produce ellagic acid with relatively high levels of ellagitannin acyl hydrolase, cellulase and xylanase. Ellagitannins concentration, initial pH, T. reesei and A. oryzae during the fermentation were identified as important process parameters effecting ellagic acid...
Ellagic acid production from cups extract of valonia acorns by pure and mixed cultures of Aspergillus oryzae and Trichoderma reesei was investigated. Ellagitannin acyl hydrolase and xylanase as well as cellulase during the pure and mixed cultures were also determined. The results revealed that mixed culture could produce higher ellagic acid yield (23%) than either of pure culture. And it was found...
