On the whole, this research mainly included two aspects:(1) To screen and ferment the strains producing the aimed enzyme and study on the enzymatic synthesis reaction of natural benzaldehyde.

其研究内容主要包括两个方面：(1)产酶菌种的筛选、发酵以及酶催化合成天然苯甲醛反应的研究通过大量实验，采用常规方法培养时，共筛出1 81株对肉桂醛有耐受性的菌株；将常规培养基换成细菌培养基以后，共筛出36株菌。

31DH suspend in the dry red wine and ferment,the density of the dry immobilized 31DH was changed by various materials.

通过选用不同的材料调节干固菌胶粒的比重，使固定化酒类酒球菌31DH悬浮于干红葡萄酒中进行苹果酸—乳酸发酵，并测定这些材料对固定化胶粒相对扩散系数的影响。

Two outstanding fusants SR-7 and SR-T19 were chose out in the fusion group 90-11×FR-008, the former produces not only antibiotics the parents produced but also a new antibiotic effective gainst a wide range of both gram positive and negative bacteria, which the parents could not produce, and its product of the 37℃ fermentation was very effective against the cotton seedling damping off caused by Rhizoctonia sonali while product of the 26℃ was effective agaist the bacterial rots of turnip and Chinese cabbage; the latter have a much stronger activity against a wide range of fungi and yeasts than the parents.

在90-11×FR-008融合组合中，筛选获得2个优良融合子SR-7和SR-T19，前者除产生亲本产生的抗生素外，还产生亲本不产生的一种新的具有广谱抗细菌活性的碱性水溶性抗生素，防病试验表明，其37℃发酵产物对棉花苗期立枯病具有良好的防治效果，28℃发酵产物对萝卜和大白菜具有明显的防腐作用；后者与亲本FR-008的抗菌谱完全一致，但其活性强度都超过了FR-008；采用RAPD分子标记技术检测了SR-7和SR-T19与亲本的同源性及彼此间的差异，从而首次直接从DNA分子水平上验证了链霉菌的原生质体融合子及其遗传重组的多样性。
