摘要: |
采集广西象州温泉水样,用常规的稀释涂布法分离和纯化嗜热菌,并选择其中1株编号为XZ2K2的菌株进行形态观察、生理生化鉴定和16S rDNA序列分析。结果从温泉水中分离得到9个菌株,XZ2K2菌株的革兰氏染色阳性,无芽孢,细胞呈杆状,最适生长温度为70~75℃,最适的生长pH值为7.0~7.5.初步鉴定该菌株为布氏栖热菌(Thermus brockianus)。 |

Abstract: |
In order to separate and identify the thermophilic lecteria in hot springs of Xiangzhou,Guangxi,the general method of dilution spread was used.One strain was selected and labelled as XZ2K2.Morphological observation,physiology-biochemistry tests and 16SrDNA sequence analysis have been conducted.Nine strains were separated from the hot springs.XZ2K2 is bacillus,gram-positive,non-sporulation.Its optimum temperature for growth was between 70℃ and 75℃,optimum pH for growth was between 7.0 and 7.5.XZ2K2 was identified as Thermus brockianus. |
