摘要
从腾冲热海分离到最高生长温度达 80℃的一株嗜热非芽孢菌RH99- 0 2菌株 ,经鉴定属Thermus属。对其所产类胡萝卜素进行了吸收光谱扫描及薄层层析分析。发酵研究表明振荡培养时的菌体生物量和色素产量上均高于静置培养 ,培养至 50h菌体生物量和色素产量达到最大值 ,菌体色素产量为 762 μg/g干重。
A thermophile Thermus sp. with the growth temperature up to 80℃ was isolated from Rehai, Tengchong, Yunnan. The yield of its β-carotenoids was higher in shaking condition than in stationary condition. When cultivated for 50hours, the pigment and the biomass yield maximally reached 762μg per gram of dry cells and 0. 568 gram of dry cells respectively. The TLC and optical absorption analysis of the carotenoids were shown.
