<p><em>Botryococcus</em> sp. is one of microalgae species that has a high lipid content as much as 75% of their dry weight. But, lipid production by microalgae is regulated by their environmental condition (pH, light, temperature, nutrition, etc). Mutagenesis induced by Gamma <sup>60</sup>Co irradiation can be utilized to alter the <em>Botryococcus</em> sp. genetic to get microalgae mutant strain that can produce a higher lipid content than the wild strain. <em>Botryococcus</em> sp. was irradiated with different doses of gamma ray of <sup>60</sup>Co  (0, 2, 4, 6, and 10 Gy),  and the effect  on the growth, lipid content, and fatty acid composition of microalgae were observed. Research design used is random complete (RAL) with 95 %  confident level for quantitive analysis based on the biomass and lipid contents. More over fatty acid composition was analyzed by Gas Cromatography-Mass Spectrometry<em> </em>(GC-MS). Results showed that Gamma irradiated gave an effect on growth and lipid content of <em>Botryococcus</em> sp. But between the control treatment (0 Gy) with microalgae irradiated dose of 2 Gy, 4 Gy and 6 Gy were not significantly different. Whereas between the control with 10 Gy irradiated was significantly different. The highest biomassa and lipid content are found in 10 Gy irradiated microalgae with 0.833 gram biomass and 41% lipid content. Fatty acid profile of <em>Botryococcus</em> sp. control has 6 fatty acids while 10 Gy irradiated microalgae has 12 fatty acids, with the long-chain fatty acids increased, whereas short-chain fatty acids decreased.</p>

Fatty Acid Compositions

The fatty acid compositions of sclerotia of Botrytis tulipae, Sclerotinia borealis, and Sclerotinia sclerotiorum produced under specific culture conditions have been compared with those of sclerotia isolated from natural environments. In each organism the lipids of sclerotia isolated from host plants were more unsaturated than those of cultured sclerotia. Fractionation of sclerotial and mycelial lipids of S. sclerotiorum revealed that the neutral lipid component was more unsaturated than the polar lipid component. In cultures of S. sclerotiorum the fatty acid composition of both mycelial and sclerotial lipids was affected by the incubation temperature, becoming more unsaturated as the temperature was lowered, Irrespective of incubation temperature the fatty acid composition of S. sclerotiorum snowed quantitative differences from the "parent" mycelium in that sclerotia consistently contained a greater proportion of oleic acid and correspondingly smaller proportions of palmitic, stearic, and linolenic acid.

Biodiesel Synthesis

The lignocellulosic hydrolysate was used as the fermentation feedstock of Rhodotorula mucilaginosa Y-MG1 for the production of microbial lipids as the potential raw material for biodiesel synthesis. On synthetic media and under nitrogen-limiting condition, the Y-MG1 strain produces 2.13 g/L of lipids corresponding to 32.7% of lipid content. This strain was able to assimilate a wide range of substrates, especially C5 and C6 sugars as well as glycerol and sucrose. Fatty acid composition shows a divergence depending on the nature of used carbon source with a predominance of oleic acid or linoleic acid. An effective hydrolysis process, based on diluted acid treatment, was established for providing the maximum of fermentable sugars from different characterized lignocellulosic wastes. The highest yield of reducing sugars (56.6 g/L) could be achieved when wheat bran was used as the raw material. Hydrolysate detoxification step was not required in this study since the Y-MG1 strain was shown to grow and produce lipids in the presence of inhibitors and without the addition of external elements. Operating by controlled fed-batch fermentation yielded a dry biomass and oil yield of up to 11 g/L and 38.7% (w/w), respectively. The relative fatty acid composition showed the presence of increased levels of monounsaturated (66.8%) and saturated (23.4%) fatty acids in lipids of Y-MG1 grown on wheat bran. The predictive determination of biodiesel properties suggests that this oil may effectively be used for biodiesel production.
