DYNAMICS OF INORGANIC PHOSPHORUS CONSUMPTION BY MICROCOLEUS-CHTHONOPLASTES CELLS

The dynamics of inorganic phosphorus consumption by cells of the cyano bacterium Microcoleus chthonoplastes, isolated from littoral lagoons o f Lake Sivash, has been studied. The P(i) content in M. chthonoplastes living cells was shown to vary within a wide range and to depend upon the growth phase. The threshold phosphorus concentrations and the max imal phosphorus amount which could be accumulated by cells were determ ined. Phosphorus consumption by cyanobacterial cells was most intense within the first hours of growth, which was clearly shown in phosphoru s-limited cells.
