研究了褐藻酸降解菌的筛选及利用其降解海带和裙带菜的方法及适宜条件。结果表明,褐藻酸降解菌更易降解嫩海藻,其降解能力与菌液或酶液的pH、盐度有很大的关系,先培养细菌离心后降解海藻、培养细菌后不离心降解海藻、培养细菌与降解海藻同时进行这三种方式对海藻都有降解能力,但效率依次降低。 The screening of alginate-degrading bacteria and the methods of using them to degrade kelp and wakame and the suitable conditions were studied. The results showed that alginic acid-degrading bacteria could degrade the marine algae more easily. The degradation ability of alginate-degrading bacteria was closely related to the pH and salinity of the bacterial liquid or enzyme solution. After culturing the bacteria, the algae were degraded by centrifugation, And the degradation of seaweed at the same time these three methods have the ability of seaweed degradation, but the efficiency of the order.
