ABSTRACT
The efficiency of Cryptococcusalbidus was evaluated for its abilities to assimilate onion and apple hydrolysates as a medium for lipid production. Onion waste (OW) and apple waste (AW) were hydrolysed at an organic load of 2% total solids by indigenous microbes under mesophilic conditions. The indigenous microbes effectively hydrolysed both wastes giving the highest reducing sugar content of 4.8 g/L and 10.8 g/L with OW and AW hydrolysates, respectively. The microbiome analysis revealed that most of the indigenous microbes belonged to genus Bacillus and a significant population of α-proteobacteria and γ-proteobacteria were also present. Cell retention culture of C. albidus at a dilution rate of 0.01 h-1 resulted in a total dry cell weight (DCW) of 13.5 g/L with an intracellular lipid content of 20.0% at 168 h, corresponding to an enhancement of 3.48-folds and 2.37-folds in DCW and lipid concentration, respectively, as compared to batch fermentation.
