[Evaluation of cell nitrogen and phosphorus quotas in accumulative cultures of chlorococcous algae]

A conceptual model of cell quota was proposed and the parameters were determined that characterize the quota dynamics during the development of algae. Based on the experimental and empirical-statistical procedures of analysis, the basal parameters of cell quotas of nitrogen and phosphorus were obtained for four species of chlorococcous algae. The data were also obtained on a variability of nitrogen and phosphorus quotas during the development of algae, as well as coefficients of excessive accumulation. The phosphorus quota changed within the limits of three orders of magnitude and the nitrogen quota, within the limits of one order. The highest coefficients of excessive accumulation were 52 and 1.8 for phosphorus and nitrogen, respectively.
