Abstract

Highlights: First MCA to rank microorganisms from various classes for biodiesel production. Oil production by various microorganisms was studied on different carbon sources. Major fatty acids: palmitic, stearic, oleic and linoleic acid. A. oryzae, M. plumbeus and R. mucilaginosa scored positive Phi from PROMETHEE II. Fungi strains showed superior performance across majority of criteria from GAIA Webs. Abstract: Oleaginous microorganisms have potential to be used to produce oils as alternative feedstock for biodiesel production. Microalgae ( Chlorella protothecoides and Chlorella zofingiensis ), yeasts ( Cryptococcus albidus and Rhodotorula mucilaginosa ), and fungi ( Aspergillus oryzae and Mucor plumbeus ) were investigated for their ability to produce oil from glucose, xylose and glycerol. Multi-criteria analysis (MCA) using analytic hierarchy process (AHP) and preference ranking organization method for the enrichment of evaluations (PROMETHEE) with graphical analysis for interactive aid (GAIA), was used to rank and select the preferred microorganisms for oil production for biodiesel application. This was based on a number of criteria viz ., oil concentration, content, production rate and yield, substrate consumption rate, fatty acids composition, biomass harvesting and nutrient costs. PROMETHEE selected A. oryzae, M. plumbeus and R. mucilaginosa as the most prospective species for oil production. However, further analysis by GAIA Webs identified A. oryzae and M. plumbeus as the best performing microorganisms.
