Abstract

Chrysotila lamellosa Anand. has been isolated from both fresh and marine habitats, and shows the ability to grow in salinities from 2‰ to 32‰. The growth of the alga was measured within this range of salinities, and it was found that the growth rate at low salinities was greater than at high salinities. This was related to the production of zoospores in the cultures. The content of chlorophylls and carotenoids was also measured within this range of salinities and it was shown that the pigment concentration tended to rise with increasing salinity. The release of zoospores was also investigated and was shown to be moderated by salinity, temperature and aeration. These results were compared and indicate that the alga is under environmental stress at low salinities, and better adapted to growth at salinities above 16‰.
