Краткое описание

The method of separate cultivation of Scenedesmus quadricauda (Turp.) Bréb. cenobia, which made it possible to establish relationship between resting, dead, and multiplying cells in the model population of the alga, was elaborated. The contribution of resting cells to the total numbers of the alga at all stages of the growth of its population accounted for 45−70%. The highest contribution of multiplying cells (up to 45%) to the total numbers of the alga was observed at the exponential stage of its growth. At all stages of the alga growth, the contribution of dead cells was not more than 20%. Dead cells were decomposed for 2−3 hours.
