麻疯树籽毒蛋白抑菌活性初步研究

Study on the Antibacterial Activity of Toxic Protein from Jatropha Seeds

通过浸泡、匀浆、离心、干燥等工艺,得到了麻疯树毒蛋白,将该蛋白进行抑菌活性研究,得到了如下研究结果:对酿酒酵母、毛霉和根霉具有较强的抑菌活性,对毛霉和根霉的最低抑菌浓度(MIC)不超过1.5 g/L,对酿酒酵母最低抑菌浓度不超过1.0 g/L,而其对大肠杆菌和枯草芽孢杆菌抑菌作用不明显。抑菌的最佳p H值。

The toxic protein from Jatropha curcas seeds by soaking,homogenization,centrifugation and drying was studied on antibacterial activity. The result showed that the toxic protein hads strong antibacterial activity to Saccharomyces cerevisiae,Mucor pusillus and Rhizopus chinensis,and the MIC was 1. 0 g / L,1. 5 g / L and 1. 5 g / L,respectively. However,the toxic protein had no obviously effect on E. coli and Bacillus subtilis.
