Краткое описание

The growth of certain blue-green algae and the pigment composition of their photosynthetic apparatus were studied under the influence of acetazolamide and ethoxyzolamide. As demonstrated in the study, these inhibitors exerted no real effect on the accumulation of biomass of Spirulina platensis (Nordst.) Geitl. or on the content of chlorophyll a, carotenoids, and phycobiliproteins in it. At the same time, the accumulation of biomass by two strains of Nostoc linckia (Roth) Вот. et Flah. (isolated from the opposite slopes of "Evolution Canyon" in Mount Carmel Natural Preserve, Israel, and differing sharply in climatic conditions) was inhibited by acetazolamide and was completely depressed by ethoxyzolamide at a concentration of 0.5 mM. The introduction of these inhibitors into the medium led to substantial changes in the pigment apparatus of both strains. Clear differences were also observed in sensitivity of N. linckia strains to inhibitors of carboanhydrase. Mechanisms of inhibitors' action are discussed.
