Photosynthetic Pygments Content and Growth of Microalga Plagioselmis prologa (Cryptophyta) Under Low Salinity

Abstract

Low salinity influence on chlorophyll a and carotinoid content and growth of microalgae Plagioselmis prologa (Cryptophyta) was studied. It were shown, that photosynthetic content decreased under salinity 24‰, compare with control (32‰), but alga growth didn’t affected. Salinity reduction to 16‰ provoked more significant lowering of the parameters compared with control. Salinity 8‰ lead to the most negative effect on the alga.
