ABSTRACT

The survival of two algae, Prorocentrum micans and Serratia costatum, were studied in the natural environment and in the laboratory under the artificial light radiation conditions in the presence or absence of UVB radiation. The effect of elevated temperature and UVB radiation for cultures of two algae was examined. UVB radiation decreased the growth of two algae; Prorocentrum micans was more affected by UVB radiation than Serratia costatum. Artificial UVB radiation for 4 h decreased the motility by 20% for Serratia costatum and by 40% for Prorocentrum micans. Elevated temperature and UVB radiation decreased the growth rate of two algae.
