微藻是光合植物样生物，被认为是可持续生产各种产品（例如食品和食品补充剂，生物燃料或动物饲料和水产养殖）的快速增长来源。目前，商业化利用的一些瓶颈是生产产量的低效率、敏感产品的高效收获技术和高建立成本。光，其质量以及数量，是微藻生长和代谢的主要关键参数。因此，人工照明提供了一种选择，可以提高微藻生物量的产量，并在规定的条件下增加特殊代谢物。另一方面，人工照明是一个非常昂贵的因素。研究了不同光周期（小球藻14：10、20：4、22：2、24：0-h和栅藻16：8、18：6-h）对单细胞绿色藻C. vulgaris和S.阿古斯初步结果表明，S.光周期对叶绿素a和叶绿素B、叶黄素、β-胡萝卜素、虾青素和α-亚麻酸含量的影响不显著。然而，基于在相关光周期中获得的生物量和细胞浓度，这些化合物的可能收获产量在两个物种中相似，或者仅比S.阿古斯
Microalgae are photosynthetic plant-like organisms, which are considered to be a fast growing source for a sustainable production of various products (e.g. food and food supplements, biofuels or animal feed and aquaculture). Currently, some of the bottlenecks for the commercial use are the low efficiency of production yields, efficient harvesting technologies for sensitive products and high establishment costs. Light, its quality as well as quantity, is a main critical parameter for microalgal growth and metabolism. Thus, artificial lighting offers the option of improved production of microalgal biomass as well as increases in special metabolites under defined conditions. On the other hand, artificial lighting is a highly expensive factor. The aim of the present study is to investigate the influence of several photoperiods (14:10, 20:4, 22:2, 24:0-h for Chlorella vulgaris and additional 16:8, 18:6-h for Scendesmus obliquus) on the biochemical profile of single-celled green algae C. vulgaris and S. obliquus. Preliminary results indicated that S. obliquus showed higher cell contents of proteins, chl a and chl b, lutein, beta-carotene, astaxanthin and alpha-linolenic amounts independently from the photoperiod. However, based on the achieved biomass respectively cell concentration in the related photoperiods, the possible harvest yield of these compounds is similar in both species or just little more effective by S. obliquus.
