OPTIMIZATION OF 6-PENTYL-ALPHA-PYRONE PRODUCTION BY SOLID STATE FERMENTATION USING SUGARCANE BAGASSE AS RESIDUE

Abstract

Solid state fermentation (SSF) has been used as a model for the study of metabolism and physiology of microorganisms. The aim of the present study was to enhance 6-PP production by Trichoderma harzianum 4040 in solid state fermentation using sugarcane bagasse as a residue. A fractional factorial design was used to select the components of the nutrient solution. The fermentation was carried out during 9 days, and the aroma extraction was done on the third, fifth, seventh, and ninth days using organic solvent. On the seventh day the major concentration of 6-PP was found. The variables glucose, sucrose, and MgSO4 were found to be significant statistically (p> 0.05) as components of the nutrient solution used in the production of 6-PP by filamentous fungi in SSF using sugarcane bagasse as a residue. GC-MS was used for quantification of 6-PP aroma.
