Mutant microalgae Nanochloropsis oculata. and Chlorella sp
included in this study exhibited a high potential for energetic lipid storage
as well as high growth rates comparing to the un mutants (standard), therefore,
considered promising candidates for advancing the biofuel production. In
addition to the exponentially increase in biomass carbohydrates, proteins and
fatty acids remarkably increased after these strains were mutated by ethyl
methane sulphonate (EMS), while total lipids decreased. Biochemical
compositional analysis was carried out by using gas chromatography to find out
concentrations of five major fatty acids: Palmitic acid, Lenolenic acid,
Stearic acid, Oleic acid and Linoleic acid. In mutant N. oculata and Chlorella
sp. Lenolenic acid is the fatty acid
with high percentage (11.7 and 4.8 %) respectively compared with un- mutant (0.241
and 1.824) %. Five fatty acids were selected to assess effect of the mutation,
which revealed that initial concentrations of all the fatty acids before the
mutation were multiplied about 48, 16, 14, 7 and 6 fold of Lenolenic, Palmitic,
Oleic, Stearic and Linoleic acids respectively in N. oculata, while slightly
changes occurred in the concentrations of Chlorella sp fatty acids.
