A multi-criteria analysis approach for ranking and selection of microorganisms for the production of oils for biodiesel production

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.

Optimization of cultivation conditions for biotechnological production of lipid by Rhodotorula kratochvilovae (syn, Rhodosporidium kratochvilovae) SY89 for biodiesel preparation

“…This results lead to selection of glucose as a carbon source for further studies. This confirms the results obtained by other researchers that glucose is the preferred carbon source for lipid production by oleaginous yeasts (Patel et al 2014;Ahmad et al 2015;Enshaeieh et al 2015).…”

“…The total lipids of this yeast contained mostly oleic acid (C18:1) (53.82 ± 1.25%), followed by palmitic (C16:0) (18.63 ± 0.53%), linoleic (C18:2) (13.34 ± 1.15%), stearic (C18:0) (5.68 ± 0.32%), linolenic (C18:3) (5.47 ± 0.60%) and palmitoleic (C16:1) (0.50 ± 0.09%) acids. Similar results on major fatty acid profiles of different oleaginous yeasts were reported by other researchers (Ahmad et al 2015). The fatty acid profiles that were exhibited by SY89 were not only similar to fatty acid profiles of other oleaginous yeasts, but also they are similar …”

Evaluation of lipid biosynthesis ability by Rhodotorula and Sporobolomyces strains in medium with glycerol

“…However, in that case, the lipids contained more C18:1 (over 55 %) and C18:3 (over 4.6 %). Similarly, a higher share of C18:3 in lipids of R. mucilaginosa was noted by Ahmad et al [2]. In the lipids of the same species, Kataray and Domnez [23] determined only 6.5 % of linoleic acid among all PUFA.…”

Comparative Analysis of Synthetic Natural Gas versus Hydrogen Production from Bagasse

“…The appraisal of several engineering development projects involves consideration of different decision criteria. The multicriteria framework allows such factors to be presented in a comprehensive and consistent format . Simple Additive Weighting (SAW) is the oldest, most widely known and practically used method for multivariable analysis.…”
