Abstract |
A total of 28 strains of 19 Penicillium species were isolated in
a survey of extracellular enzyme-producing fungi from macroalgae
along the coast of Jeju Island of Korea. Penicillium
species were identified based on morphological and β-tubulin
sequence analyses. In addition, the halo-tolerance and enzyme
activity of all strains were evaluated. The diversity of
Penicillium strains isolated from brown algae was higher than
the diversity of strains isolated from green and red algae.
The commonly isolated species were Penicillium antarcticum,
P. bialowiezense, P. brevicompactum, P. crustosum, P. oxalicum,
P. rubens, P. sumatrense, and P. terrigenum. While many
strains showed endoglucanase, β-glucosidase, and protease
activity, no alginase activity was detected. There was a positive
correlation between halo-tolerance and endoglucanase
activity within Penicillium species. Among 19 Penicillium
species, three species–P. kongii, P. olsonii, and P. viticola–
have not been previously recorded in Korea. |
