| 摘 要： | 琼胶酶能降解琼胶多糖，生成琼胶寡糖。这些降解产物在食品等方面有良好的应用价值。本研究从江蓠中分离筛选到两株琼胶酶高产菌，编号分别是2．1-f和1.1-e，它们均为革兰氏阴性菌，呈细杆状。通过API条带分析，它们除了在对柠檬酸盐的利用上存在差别外，其它的生理生化特征完全相同，最终确定它们均为Sphingobacterium multivorum(多食鞘氨醇杆菌)，其可信度分别是98．7％和99．5％。

| Abstract: | Agarase can hydrolyse agar, producing agaro-oligosaccharides. These hydrolysing products have shown certain application values in food industry and other sectors. In this study, two powerful agarase-producing marine bacteria were isolated from Gracilaria species, designated as strains 2.1-f and 1.1-e. Microbiological studies showed that they are all Gram negative, rod-shape. By means of API analysis, they were identified as Sphingobacterium multivorum despite some tiny variations between them. |
