The fungicidal activity of methanol extract was higher than that of ethyl acetate extract, and the inhibition rates were higher than 90% against Alternaria longipes, Fusarium oxysporium, Gibberella zeae, Glomerella cingulata, Exserohilum turcicum under the concentration of 1000g/mL The results of the inhibition of spore germination indicated that the fermentation products exhibited obvious inhibition rate against Alternaria longipes, Exserohilum turcicum and Fusarium coeruleum, the EC50 values was 59.4g/mL, 96.5g/mL and 132.5g/mL. In the bioassay of the fermentation products against Bacillus sub tills and Bacillus cereus, by means of detection fo inhibition zone, the inhibition zone diameter was 20mm and 27mm. The results of pot tests that methanol extract showed higher than 70% of protective efficacy and therapeutic efficacy against wheat powdery mildew under the concentration of 2000g/mL.

其中，甲醇提取物的抑菌活性比乙酸乙酯提取物强，在1000g/mL浓度下对烟草赤星病菌、马铃薯干腐病菌、小麦赤霉病菌、苹果炭疽病菌、玉米大斑病菌的菌丝生长抑制率均大于90%；抑制孢子萌发法试验结果表明，2K3菌株菌丝体的甲醇提取物对烟草赤星病菌玉米大斑病菌和马铃薯干腐病菌的EC50分别为59.4g/mL、96.5g/mL和132.5g/mL；管碟法生测结果表明，2K3菌株菌丝体的甲醇提取物对枯草芽孢杆菌和蜡状芽孢杆菌的抑菌圈直径分别为20mm和27mm；盆栽试验结果表明，2K3菌株菌丝体的甲醇提取物在2000g/mL浓度下对小麦白粉病的治疗和保护作用均在70%以上。

However, they have their respective shortcomings in mosquitocidal spectrum, persisting and resist-mosquito management. In this research, the mosquitocidal toxin genes cry4Ba and cry11Aa from Bacillus thuringiensis and btx gene from Bacillus sphaericus were co-expressed.cry4Aa,cry4Ba and cry11Aa genes were also co-expressed with btx gene seperatedly and in combination.The constructed recombinants had a high toxicity against susceptible and resistant mosquito.

本研究将苏云金杆菌以色列亚种的杀蚊毒素基因cry4Ba和cry11Aa与球形芽胞杆菌的二元毒素基因btx两种杀蚊菌的杀蚊毒素基因进行了重组，将Bti杀蚊毒素基因cry4Aa， cry4Ba， cry11Aa及Bs的杀蚊毒素基因btx单独或组合表达，所得工程菌株对敏感和抗性库蚊的毒力均有提高，不仅提高了杀蚊毒力，扩大了杀蚊谱，而且部分克服了蚊幼虫对Bs的抗性。

Identification of extensive phenotypic information to 6 pare cultures and detection of the mol% G+C ratio of the DNA to representative strains, showed that the examined bacteria belonged to a new morphovar of Acinetobacter junii, and was designated as Acinetobacter junii Morphovar Ⅰ. In addition, serotype, antibiotic sensitivity and pathogenicity of isolates were studied, the results showed that the 6 strains have the same K-antigen and O-antigen, there arc no obvious differences in sensitivity and resistance to used 37 antimicrobial agents between strains, and have strong pathogenicity to experimental stone bonder and Bastard halibut.

经对6株纯培养菌在形态特征、理化特性等方面较系统的表观分类学指征鉴定及代表菌株DNA中G+C mol%的测定，表明为琼氏不动杆菌的一个新形态型并定名为琼氏不动杆菌形态型Ⅰ(Acinetobacter junii morphovar Ⅰ)；同时，对该菌进行了血清型、对抗菌类药物的敏感性及致病作用等方面的试验，初步表明此6株菌具有同种的表面及同种的菌体抗原，对供试37种抗菌类药物在不同菌株间的敏感及耐药无明显差异，对供试石鲽及牙鲆均具有较强的致病作用。
