Study on Extraction and the Physicochemical Property of Purple Pigment from Fusarium sp.JN158

Abstract:

The optimum conditions of extracting purple pigment from the culture of Fusarium sp JN158 were studied,and then the physicochemical properties were analyzed.The results showed that the purple pigment could be extracted with 95% ethanol(pH=1).Under the acid condition,the pigment was stable to heat,light,citric acid,and sodium benzonate.the maximum absorption wavelengh were 310nm and 510nm,which affected by H2O 2 and Na2SO3;Sucrose and Glucose had the hyperchromic effect;The pigment was influenced by Fe3+,Al3+,K+,Cu2+,Mg2 +,but Mg2 +,Zn2 +,Na+,Ca2 + could not badly affect it at all.
