Abstract

Abstract

A marine fungus Penicillium crustosum 2A4-Z15,which has strong inhibition activity,w as separated from South China Sea and identified.It was treated by four biotic elicitors and five abiotic elicitors.Four biotic elicitors originated from different marine microorganism including Bacillus sp.,Penicillium sp.,Trichorderma sp.and Fucarium sp..Five abiotic elicitors included three aminoacids used as precursors and two inhibitors.The effect of different elicitors on alkaloid metabolism of the marine fung us was studied.The results show that different elicitors have different effecton alkaloid metabolism and biomass.Generally speaking,biotic elicitors have evidently positive influenceon them.Aminoacids added as precursors can show positive influence only with proper kind and concentration.Inhibitors tested both show negative influence.Alkaloid metabolism can be enhanced by 44.1% by the marine bacterial elicitor with a 10μg/cm³ concent ration added at logarithmic period
