摘要
早在1934年,Waksman就已经从海水和海底沉积物中以及藻体上分别分离到能降解褐藻酸的细菌。在《伯吉细菌鉴定手册》中曾经把具有降解褐藻酸能力的假单胞菌组成藻酸单胞菌属(A1ginomonas),其中多数种来源于海洋。后来,由于这个属的描述特征与某些属的界限不够清楚,在《伯吉细菌鉴定手册》第八版中又取消了这个属的名称,并据所属种的生理生化特征分别归人有关的属。
The present paper deals with the action of alginic acid decomposing bacteria and A-l strain’s alginase on haidai(Laminaria japonica Aresh).1.The alginic acid decomposing bacteria were frequently isolated from cultivated haidai by using alginate agar supplemented with algae extract of Laminaria.Most of these isolates were able to grow and reproduce on the blades of haidai without any additional requirements.We found that these bacteria were the dominating inhabitants on the blades of cultivated Haidai.2.The crude enzyme preparation of A-l strain was made.The blades of haidai could be completely decomposed by the actiens of A-l strain or it’s crude enzyme after 3-5 days.3.Relationship between the alginic acid decomposing bacteria and cultivated Laminaria was discussed.
