Aspergillus terreus variant TB21 wet biomass optimized by in-situ transesterification for biodiesel production.

ABSTRACT: The oleaginous fungus, Aspergillus terreus when subjected to random chemical mutagenesis led to isolation of TB21 variant with improved lipid content (78.1%) as compared to wild type (49.8%). The fungal wet biomass grown on sugarcane bagasse hydrolysate (SCBH) was subjected to one-step in-situ (direct) acid transesterification to optimize its conversion to biodiesel using a 2-level factorial statistical design of experiments. The process optimization revealed that wet biomass and methanol were the most significant factors and in a short reaction time period of 5 min with low methanol: wet biomass ratio (10:1) influenced FAME production Statistical optimization studies showed that TB21 exhibited a higher FAME content of 76.5 and 38.1% (w/w) from wet and dry biomass, respectively when compar
