实验对正常海带用褐藻酸降解菌进行人工感染 ,经培养使其产生烂斑 ,通过组织显微切片进行比较观察 ,发现褐藻酸降解菌首先侵入内皮层 ,然后再逐渐侵入到外皮层、髓部 ,最终导致海带病烂。切片中发现在侵染海带切片内皮层的细胞中 ,有大量储藏颗粒 ,形状为椭圆或圆形。其直径范围在 1.5～ 4 .0 μm之间 ,平均直径为 2 .7μm。该颗粒主要存在内皮层 ,从其产生到消亡的过程分析 ,与褐藻酸降解菌的侵入有关 ,并作为营养起到促进菌增殖的作用。
Experiments on normal seaweed artificial infection with alginic acid degrading bacteria, the culture to produce rotten spots, microscopic sections were observed by tissue comparison and found that alginate-degrading bacteria invade the endothelium first, and then gradually invaded the outer cortex, medulla , Eventually leading to kelp diseased. Slices found in the inner layer of cells infected with kelp slice cells, a large number of storage particles, the shape of an oval or circular. Its diameter range between 1.5 ~ 4 .0 μ m, the average diameter of 2. .7 μ m. The particle mainly exists in the endodermis, from the process of its production to extinction, it is related to the invasion of alginate-degrading bacteria and plays a role of promoting the proliferation of bacteria.
