摘要
随着人们生活水平的提高,微生物天然色素则以安全性高、具有一定的生物学功能而成为研究热点。少数放线菌也能产生天然色素,其中包括罕见的天然蓝色素。蓝色素作为3个基本色素之一,它可与红、黄品系的天然色素调配成多种色调,使天然色素更加丰富。因此,本研究为获得优良的产色素的微生物资源,本研究对一株产蓝色素的菌株进行了种属鉴定,并对菌株对碳源的利用情况和色素性质进行分析,同时对pH、光线、金属离子、温度等因素对色素的稳定性影响进行检测。结果表明该菌株属于暗蓝色链霉菌;该菌株产生的蓝色素为脂溶性色素;最适培养温度为29℃、pH7.3;此外,金属离子、光照、氧化剂、还原剂等因素对蓝色素的产生都有不同程度的影响。该研究成果对该链霉菌蓝色素进一步的开发应用奠定基础。
With the improvement of living level,Many researchers have attention to the natural pigments because of having the high security and the certain function.A minority of Actinomyeetes can produce rare blue pigment.As one of the three basic pigment,blue pigment has high value,it can be deployed into a variety of colors.In order to make use of natural pigment produced by microbiology,a blue-pigment producing Actinomyeetes was studied extensively in this paper.According to analysis of the morphology and physiological & biochemical characteristics,as well as detection of pH,light,metal ions,temperature and other factors affect the stability of the pigment.This strain could be identified as Streptomyces caeruleatus,Gram-positive and the blue pigment is fat-soluble.The optimum temperature is 29 ℃.The optimum pH7.3.Metal ions,light,oxidants,reducing agents,and other factors have some impact on the blue pigment.The study provided reference basis for excavating the pigment producted by Streptomyces caeruleatus.
