The present investigation aimed to study antimicrobial activities in marine microalgae, screened from Moroccan coastlines. Ethanolic extracts were prepared from the microalgae and evaluated each against the bacteria: Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus, the yeast Candida albicans and the fungus Aspergillus niger. The highest antibacterial activity was found in the extract of Tetraselmis sp. which exhibited an inhibitory effect against the three bacteria with a MIC of 2.6 to 3.0 mg extract per mL culture. Extracts from the other microalgae: Dunaliella Salina, Nannochloropsis gaditana, Dunaliella sp., Phaeodactylum tricornutum and Isochrisis sp. each showed inhibitory activity against E. coli or P. aeruginosa with a MIC of 2.6 to 4.3 mg extract per mL. The extract of N. gaditana also inhibited S. aureus growth. However, the extracts from the microalgae, Chaetoceros sp. and Chlorella sp. showed no effect under the applied experimental conditions. All the tested extracts inhibited the growth of C. albicans; the highest activity was obtained from N. gaditana with a MIC of 4.0 mg extract per mL culture. Aspergillus niger appeared to be resistant to the effect of the extracts. The observed antimicrobial activities were linked to the contents of the extracts in fatty acids, carotenoids and phenolic compounds. In conclusion, the studied microalgae could be considered as a potential natural source of bioactive compounds with antimicrobial activities.

The fossil fuel consumption has been swiftly increase by the robust industrialization and increasing living standard of society. So the biodiesel fuel becomes more popular material among the research for get ride over these problems because it is green fuel, sustainable and renewable. A microalga is the fastest growing species with high oil cosntents (up to 60%). In organic solvent extraction method, polar (methanol) and non-polar (hexane) solvents are preferred for oil extraction. GLC technique is used for esterification and seventeen forms of fatty acids are identified. A large amount of Cis-11-eicosanoic acid (41.80%) is found in algae oil. Different catalysts i.e. NaOH, CaO (Egg Shell), and H2SO4, with methanol is used for biodiesel preparation. The fuel properties are premeditated for blends i.e. B10, B20, B30, B50 and B100 as per standards. Pure biodiesel attributes like density, kinematic viscosity they are within biodiesel standards. Many researches pragmatic that these physicochemical properties of biodiesel has great influence on engine performance, so this article provides guidance for examine the behaviour of biodiesel in engine based upon their physiochemical properties.

“…We also found C16:0, C16:1, C18:1 C18:2 and C18:3 which have not been reported before for C. vulgaris (Table 3). The existence of the erucic acid methyl ester (C22:0), arachidic acid methyl ester (C20:0), palmitic acid methyl ester (C16:0), cis-11-eicosenoic methyl ester (C20:1), cis-11, 14-eicosadienoic acid methyl ester (C20:2) and linolenic acid methyl ester (C18:3) might be potencial as antimicrobial agent based on the experiment conducted by Suresh et al [11]. The fatty acid composition of green alga Chlorella of 14:0, 16:0, 16:1, 16:2,16:3, 18:0, 18:1, 18:2, 18:3 is confirmed under all kinds of cultivation conditions as those mentioned by Wang et al [7].…”

Recent decades showing remarkable development of the biotechnology of microalgae. Valuable product for food, nutrition and other applications will extend into broader area. Natural nutrition production from microalgae are not yet competitive with their synthetic levels. Chlorella is widely used as a health food and feed supplement, as well as in the pharmaceutical and cosmetics industries. Protoplast fusion was found to be an efficient method in improving its nutrition production and diversification in Chlorella vulgaris. The research was carried out by application of protoplast fusion on interspecific microalgae of C. vulgaris. The fusant was subjected for analysis of nutrition content by GCMS methods on C. vulgaris powder from 100 L liquid cultivation of fusant. The research result gained fusant in high mass production level. Nutrition analysis of fusants showed 17 amino acid with high concentration glutamic acid (14495.52 ppm) followed by leucine (10856.97 ppm) and Aspartic acid (10378 ppm). Palmitic acid (1.59%) was showed highest concentration in its lipid acid profile. Lipid analysis also showed polyunsaturated fatty acids (PUFA) with concentration 1.0987% and DHA 0.2%. Surprisingly, the fusant also revealed Omega 9 instead of Omega 3 and Omega 6. The research result showed potential acquisition of improvement nutrition by protoplast fusian application on microalgae.
