1.The effect of adding anti-oxidant was better than adding adsorbent in controlling brown stain of callus. The ability of brown stain control is in the order of ascorbic acid(5 mg·L-1) > cyste-ine(100 mg·L-1) > activated carbon(1 g·L-1) .
添加抗氧化剂控制愈伤组织褐变的效果要优于吸附剂,其防褐化能力:抗坏血酸(5 mg·L-1)>半胱氨酸(100 mg·L-1)>PVP(1 g·L-1)>活性炭(1 g·L-1)。收藏指正
2.Single factor experiment and orthogonal experiment were studied on the culture conditions of stain BM01 producing flocculant, and the results suggested that sucrose was used as carbon sourse which the content of was 5‰ ,and the content of the clay mineral poweder was 2.5‰. In addition, the flocculating rate of MBF-BM01 arrived at 95.2% at pH7 of medium, when we disposed of 3‰ Kaolin clay suspension liquid.
对BM01菌株产絮凝剂的最佳培养条件进行单因子试验、正交试验，结果表明：蔗糖为碳源且含量为5‰，矿粉添加量为2.5‰，培养基初始pH值为7.0，处理3‰的高岭土悬浊液，BM01菌株产絮凝剂(MBF-BM01)的絮凝率最高为95.2％。收藏指正
