The effect of different photoperiods: 24 h illumination and a 12:12-h light/dark (12L:12D) cycle on the growth rate biomass productivity was studied in five algal species: Neochloris conjuncta, terrestris, texensis, Botryococcus braunii Scenedesmus obliquus. green microalgae examined differ reproduction mode. Continuous stimulated B. S. obliquus more effectively than microalgal species from genus Neochloris. However, under shorter duration light same intensity (12L:12D cycle), all three stimulated. Under continuous illumination, specific first phase cultures higher Neochloris, whereas 12L:12D cycle, generally that As result, regime influenced differently. maximum obtained carried out at illumination. All produced efficiently which two–threefold unicellular for time this study, are promising prospective objects biotechnology.
