“…In the case of Chlorella emersonii and C. minutissima, 63% and 56% oil were obtained in low-nitrogen media compared to 29% and 31% in high-nitrogen media, respectively. Scragg et al (2002) supported these findings by also finding that the lipid content increased in low-N medium for Chlorella strains. Dayananda et al (2007) illustrated that the content of lipid, carbohydrate and proteins varies from species to species.…”

Microalgae have emerged as one of the most promising sources for fatty acid production. Since the various fatty acid profiles (chain length, degree of unsaturation, and branching of the chain) of the different sources influence biodiesel fuel properties, it is important to possess data on how the presence of NaNO 3 as nitrogen source can influence the profile of produced fatty acids from algae. The fatty acid profiles of Desmodesmus quadricaudatus and Chlorella sp. were detected in pure batch cultures experiments. BG-11 nitrogen free medium and the medium contained 1.5 g NaNO 3 l -1 were used in this investigation. At late stationary growth phase in nitrogen free medium, Chlorella sp. produced 58.39% saturated fatty acids and 41.60% unsaturated fatty acids. While in medium contained 1.5 g NaNO 3 l -1 Chlorella sp. produced 62.08% saturated fatty acids and 37.92% unsaturated fatty acids. In nitrogen free medium D. quadricaudatus produced 66.92% saturated fatty acids and 33.07% unsaturated fatty acids. While in cultures contained 1.5 g NaNO 3 l -1 D. quadricaudatus produced 51.62% saturated fatty acids and 48.37% unsaturated fatty acids.The fatty acid profile of Chlorella sp. and D. quadricaudatus that isolated from Egyptian water body and grown in nitrogen free medium may be suitable for biodiesel production. The results discussed and compared to fatty acid profiles produced by other algal species.

“…In contrary, the average temperature of culture media during the experiments in spring was higher than 20°C, which might be more suitable for the growth of C. zofingiensis outdoors. The highest biomass productivity obtained in current study (58.4 mg L À1 day À1 ) (Table 1) was higher than the biomass productivity of C. vulgaris (40 mg L À1 day À1 ) and C. emersonii (41 mg L À1 day À1 ) cultured in 230-L pumped tubular photobioreactor indoors reported by Scragg et al (2002), indicating the advantage of outdoor culture. However, such biomass productivity was lower than the biomass productivity of Spirulina platensis (4300 mg L À1 day À1 ) reported by Hu et al (1996).…”

“…It is known that microalgae respond with physiological alterations to the environmental conditions where they grow (Valenzuela-Espinoza et al 2002, Scragg et al 2002. This behavior can be viewed as a biotechnological attribute that can be manipulated in order to control the algae biochemical composition and growth, focusing on specific compounds and higher productivity.…”

The need for clean and low-cost algae production demands for investigations on algal physiological response under different growth conditions. In this research, we investigated the growth, biomass production and biochemical composition of Chlorella vulgaris using semi-continuous cultures employing three growth media (LC Oligo, Chu 10 and WC media). The highest cell density was obtained in LC Oligo, while the lowest in Chu medium. Chlorophyll a, carbohydrate and protein concentrations and yield were highest in Chu and LC Oligo media. Lipid class analysis showed that hydrocarbons (HC), sterol esthers (SE), free fatty acids (FFA), aliphatic alcohols (ALC), acetone mobile polar lipids (AMPL) and phospholipids (PL) concentrations and yields were highest in the Chu medium. Triglyceride (TAG) and sterol (ST) concentrations were highest in the LC Oligo medium. The results suggested that for cost effective cultivation, LC Oligo medium is the best choice among those studied, as it saved the cost of buying vitamins and EDTA associated with the other growth media, while at the same time resulted in the best growth performance and biomass production.
