Abstract
Cellulolytic ability was evaluated in 19 strains of thraustochytrids, representing nine genera, using carboxymethylcellulose (CMC) as a substrate. Extracellular cellulolytic enzyme activity was determined in the culture supernatants during cell growth. CMC hydrolysis was observed in 14 out of the 19 strains examined. These belonged to the genera Aplanochytrium, Botryochytrium, Oblongichytrium, Parietichytrium, Schizochytrium, Sicyoidochytrium, Thraustochytrium and Ulkenia. On the other hand, cellulolytic enzyme activity was not detected in any strains belonging to the genus Aurantiochytrium.
