| 摘 要： | 从胡萝卜表面筛选到一株产纤维素酶活性较高的菌株HP1。使用PCR方法获得此菌株长度为1435bp的16SrDNA序列。利用生物信息学方法在美国国立生物技术信息中心NCBI基因库比对分析了该序列,发现其与Bacilluscereus相似性最高,为99%。结合菌落观察和生理生化分析,初步确定菌株HP1为Bacillussp.。序列和生化分析显示其是一株新型的芽孢杆菌,其在NCBI上的登录号是:FJ908092。

| Abstract: | In this study, a strain, HP1, with high cellulase activity was isolated from the surface of carrots. The 16S rDNA fragment of HP1 was identified to be 1435bp by PCR. The sequence was analyzed by bioinformatics method and aligned with sequences published in NCBI Genbank. This strain exhibited 99% similarity with Bacillus cereus. According to colony observation combined with physiological-biochemical analysis, HP1 was preliminarily identified to belong to Bacillus sp., which was a new strain of Bacillus based... |
