Key Achievements

  • Locally isolated, oleaginous yeast M. carribbica was found to utilize low cost substrates such as corn steep liquor, crude glycerol, cane molasses, distillery waste water with biomass concentration of 24.47 ± 0.78 g/L and lipid content of 52.09 ± 2.03%

  • Yeast Bio-refinery was set up for concomitant production of biomass, lipid, biodiesel, bioemulsifier, biocrude and animal feed component

  • Process was developed for production of bio-crude from de-oiled biomass by hydrothermal liquefaction

  • Life cycle assessment of the entire process was performed
