黑葡萄穗霉菌生防细菌LY424产天然红色素特性的研究
Study on Characteristics of a LY424 Bacterial Strain to Produce Natural Red Pigment
摘要
Abstract
[Objective] The basic characteristics of a LY424 bacterial strain which can prevent and control the growth of Starchybotrys chartarum to produce the natural red pigment were studied.[Method] To culture strain and extract pigment,determine absorption peak and color value and the influence of different conditions on the stability of red pigment.[Result] The maximum UV absorption value of the natural red pigment was at 524 nm,the color value was 66.93,the red pigment also dissolved in polar solvents very easily,its color could not be affected by pH,temperature and metal ions,easily oxidized by the strong oxidizer,at this time it was concluded that the pigment need to be kept under conditions of no light and air.[Conclusion] The red pigment has higher production and better stability,so can be used as a natural pigment resource for development.关键词
