Influence of different natural media on production of myco-diesel

Abstract

The current study was an attempt to produce mycodieselusing by six oleaginous fungal isolatesAspergillusfumigates, Aspergillusterreus, Aspergillusflavus, Trichodermaharizanum, Penicilliumsp. and Fusariumgraminearum during the culturing on natural culture media from various types of agro-wastes as prospective nutritional sources (almonds husks, peanut husks and sunflower husks).The results of biomass (dry weight) showed the higher biomass value was obtained using, almonds husks firstly (4.54, 4.64, 3.30, 3.04, 1.02, 1.00 ) g / L for six oleaginous fungal isolates A. fumigatus, A.terreus, T. harizanum, F. Graminearum, Penicilliumsp. and Fusarium graminearum respectively then followed peanut husks and sunflower husks. Likewisethe height yield of lipids using almonds husks forsix oleaginous fungal isolates were recorded high lipid productivity compared with peanut husks and sunflower husks (0.77, 1.13,0.30, 0.45, 0.05, 0.03) g / L respectively. Furthermore, the qualitative analysis of the lipids contents by gas chromatographywere identified the presence of palmitic, oleic acids, stearic acid and linoleic acid in all isolates or fatty acid methyl esteranalysis showed the predominant of saturated fatty acid than unsaturated fatty acid this indicates that the fungal lipid obtained has the same properties of biodiesel and the saturated forms give more favorable properties of biodiesel and for optimized biodiesel.
