Superfluous algal biomass hydrolysate and purified glycerol obtained from biodiesel production were utilized for the production of itaconic acid by Aspergillus niveus. The lipid extracted Gracilaria edulis algal biomass residual was subjected to a pretreatment for the enhanced production of itaconic acid. Glycerol acquired from biodiesel production was pretreated and utilized as a substrate for itaconic acid production.

Article Synopsis
  • Filamentous fungi from the genus are crucial for producing organic acids like itaconic acid (IA), which is used in various industries including synthetic fibers and adhesives.
  • The study isolated a strain (MG183809) from wastewater in Avadi, Chennai, and produced IA through submerged batch fermentation using affordable substrates like corn starch, wheat flour, and sweet potato.
  • The optimal conditions for maximum IA yield (15.65 g/L) involved using corn starch at a concentration of 120 g/L for 168 hours at pH 3.0, and the extraction process achieved a high extraction rate of 91.96%.
