Algicidal substance purified from metabolite of marine microorganism

摘要

PURPOSE: Provided is an algicidal substance purified from the metabolite of marine microorganisms which has algicidal effect on Gymnodinium sanguineum, Gyrodinium impudicum and Cochlodinium polykrikoles. CONSTITUTION: An algicidal substance purified from the metabolite of marine microorganisms is characterized by the formula:R(OH)R1OOH, wherein R has 1-5 of carbon number, and R1 has at least one of carbon number. The algicidal substances concentrated 3.7 ug/ml and 33 ug/ml show algicidal effect 90% within 12 hours and 3 hours, respectively.
