This work evaluated the potential of microalgae of Chlorella sp., SL7A, Chlorococcum sp., SL7B and Neochloris sp.,SK57 cultivated in river water contaminated with pharmaceutical effluent for biomass and lipid production. It has been observed that fast growing algae in this medium is Neochloris sp.SK57. Maximum biomass and lipid yield was obtained from Neochloris sp. SK57 (0.52 g/l) and Chlorococcum sp. SL7B (0.129 g/l)along with drycell weight of lipid was 28%.The increased in biomass and lipid in this media is could due to assimilation of organic nutrients and stress due to other components present in the river water. Fatty acid profile of algal biomass showed that saturated fatty acids production is enhanced in oils of Neochloris sp. SK57, and its suitability in food and fuel applications. Water quality of the river water was monitored before and after algal cultivation. Results showed that quality of river water was improved after algal cultivation.

制药废水污染的河水中微藻类的生物修复和生物量生产。

这项工作评估了在受制药废水污染的河水中种植的小球藻,SL7A,绿球藻,SL7B和新绿藻,SK57微藻的潜力,这些生物用于生产生物质和脂质。已经观察到在该培养基中快速生长的藻类是Neochloris sp.SK57。从Neochloris sp。获得最大的生物量和脂质产量。SK57(0.52 g / l)和Chlorococcum sp。SL7B(0.129 g / l)与脂质干细胞重量一起为28%。这种介质中生物量和脂质的增加可能是由于有机养分的吸收和河水中其他组分的胁迫所致。藻类生物质的脂肪酸谱表明,新藻属(Neochloris sp。)的油中饱和脂肪酸的产生增加。SK57及其在食品和燃料应用中的适用性。在藻类培养之前和之后监测河水的水质。结果表明,藻类培养后河水水质得到改善。
