Effect of solid substrate, liquid supplement, and harvest time on 6-n-pentyl-2H-pyran-2-one (6PAP) production by Trichoderma spp.

摘要

Selected strains of Trichoderma spp. were grown on 10 different solid media substrates and analysed for production of 6-n-pentyl-2H-pyran-2-one (6PAP). Using the highest yielding medium from this study, ground maize plus a liquid supplement, 15 Trichoderma isolates were screened, and this led to identification of 2 high yielding strains. By selection of solid media, liquid supplement and harvest time, the yield of 6PAP was improved from c. 200 to c. 1000 mg/kg. Implications of the results for development of a bulk-scale fermentation process are discussed.
