Research has recently focused on using agro-residues for growing microbial biomass as feedstock for biodiesel production. However, pretreatment of lignocellulosic biomass is necessary, increasing production costs.
Hardik Kakkad of the Savitribai Phule Pune University in India studied a fungal isolate from the tropical mangrove wetlands, Aspergillus candidus IBBG4, for its growth on waste agro-residues, such as banana peel, copra meal, corn cob, grape stalks and sugarcane bagasse, without any pre-treatment.
The resulting fungal biomass was subjected to direct acid transesterification for fatty acid methyl esters (FAME) extraction. Maximum FAME production was obtained on fungi grown in raw untreated banana peel and sugarcane bagasse. Biodiesel fuel properties of the extracted FAME were found to pass the international and national biodiesel standards, suggesting their suitability as biodiesel fuel.
The results in the study revealed the potential of A. candidus IBBG4 grown on raw untreated banana peel and sugarcane bagasse for biofuel production.
