| 摘 要： | 从海带幼苗上病烂明显处分离得到 2 3株褐藻酸降解菌 ,并对其菌落形态、细胞形态及革兰氏染色反应等进行了观察。通过对褐藻酸钠的降解实验 ,筛选出 4株具较高降解能力的菌株。感染实验表明 ,分离到的褐藻酸降解菌为海带幼苗病烂的主要病原菌。

| Abstract: | Twenty-three chains alginic acid decomposing bacteria were isolated from the rotten spots of Laminaria sporelings. The characteristics of the bacterial colonies and cells and the reactions to gram stain were observed. By the experiments of degrading sodium alginate, 4 chains with higher degrading abilities were screened out. The infection tests showed that the alginic acid decomposing bacteria isolated were the main pathogenic bacteria which caused the rot disease of Laminaria japonica. |
