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%。 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.
