Abstract:
Zeolitic products were originally used as biological filters. These products are now used in other biological processes such as the transformation of ammonium ions present in sea water into nitrite and the decomposition of fish feed. The application of zeolitic products has now been extended to the growth of marine microalgae cultures. The present paper describes the results obtained from cultures of the diatom Chaetoceros muelleri which was grown in artificial sea water in the presence of Zecer-56, a natural zeolitic product. Zecer-56 was found to significantly stimulate the growth of C. muelleri cultures.
