Abstract

Effects of differing levels of ultraviolet-B radiation on cell concentrations, maximum specific growth rates, and pigment content of the diatom Thalassiosira pseudonana were investigated. Increased UV-B compared to the base UV-B level (intended to simulate the natural level of UV-B present in the environment) tended to show detrimental effects in all parameters. When compared to our normal culture conditions (UV-B excluded), even the base level of UV-B radiation showed detrimental effects in all parameters except chlorophyll a concentrations, the only tested parameter which increased with the addition of UV-B radiation.
