Lipid accumulation potential of oleaginous yeasts: A comparative evaluation using food waste leachate as a substrate.
In present study, the efficiency of three oleaginous yeasts i.e., Yarrowia lipolytica, Rhodotorula glutinis and Cryptococcus curvatus were compared for their lipid assimilation capacities using three different FW-leachates as a medium. The FW-leachates were collected from dry anaerobic digesters and diluted to achieve carbohydrate content of 25gL-1 prior to yeast inoculations. Around 5% of yeast cultures were individually mixed in three different FW-leachate mediums and incubated under 30°C and 150rpm agitation for 6days. The Y. lipolytica produced high biomass with lipid contents of 49.0±2% on dry weight basis. Whereas, the acetic acid concentration of >6gL-1 inhibited the growth of R. glutinis. The study observed that the selection of appropriate FW-leachate composition is highly important for biolipid accumulation by oleaginous yeasts.
