Abstract

Bio-fuel has been regarded as potential alternative fuel for partial substitution of petro-diesel. The aim of the present study is to estimate the changes occur in physico-chemical properties of Jatropha curcas oil extracted from infested Jatropha seeds with six dominant fungi viz. Alternaria alternata, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Fusarium chlamydosporum and Penicillium glabrum as well as fresh seeds. Drastic changes were observed in the physico-chemical properties of Jatropha oildue to fungal infestation which affects the quality of bio-diesel. UV-visible absorbance spectra revealed that oil from fresh Jatropha seeds showed weak absorbance i.e. 0.22-0.51 with compare to fungal infested seeds ranged between 0.25-0.84 while oil from A. niger infested seeds not showed the promising absorbance. The oil colours from infested seeds were observed yellowish brown to dark brown. The acid value, saponification value and cetane values of oil from fungal infested seeds showed slight increment with compare to control. The higher cetane index of biodiesel compared to petro-diesel indicated that, it will be the high potential for engine performance. The viscosity of oil extracted from fungal infested seeds showed a decrease in viscosity which is good for biodiesel purpose while iodine values of fungal infested Jatropha seeds showed decrement in compare to control.
