Studies on the Autoinhibitor Produced by Skeletonema costatum-II. Isolation and Identification of an Autoinhibitor Produced by Skeletonema costatum.

NIPPON SUISAN GAKKAISHI, 1992
An autoinhibitor produced by Skeletonema costatum was extracted with ethyl acetate from the cultured medium. The extract dissolved in diluted aqueous NaOH was gel-filtered on Sephadex G-15 with water. The fractions which inhibited the growth of S. costatum were extracted with ethyl acetate, and the extracts were separated by preparative thin-layer ...
