And, among the antagonistic isolates 9 isolates were observed to inhibit the growth of Fusarium oxysporium, a causal agent of banana wilt, and the inhibition rates were from 80% to 100%. According to the fundamental biological characteristics, the 9 endophytic bacteria belong to the genera, Acinetobacter, Bacillus, Brevibacterium, Alcatigenes and Burkholderia. The tests showed that the hyphae of pathogen had different degrees of tumefaction and rupture.

TBA analysis showed 0.01% of TP had evident antioxidation on lipids from fish meat, and TBA increased with the TP concentration accretion presenting an unlinear relation. The effects of antioxidation of 0.03% and 0.07% of TP were close, thus, the best choice is 0.03% in practical application.5. 93 bacteria strains were isolated and categorized into several spoilage bacteria classes: Aeromonas, Vibrio, Pseudomonas, Enterobacteriaceae, Flavobacterium, Acinetobacter, Photobacteriaceae, Brevibacterium, and Micrococcus. In the early stage of storage (1～3 days), Gram-positive bacteria were the major strains and accounted for 70%, most of them belonged to Brevibacterium and Micrococcus.

TBA试验结果显示，添加00.1%以上茶多酚对草鱼脂肪都有明显的抗氧化作用，随浓度增加TBA值增加，但不呈线性关系，0.03%～0.07%抗氧化效果比较接近，从经济、有效的角度考虑在实际应用中可采用0.03%的茶多酚。5、从草鱼中分离出93株菌株，鉴定出以下几类主要腐败细菌：气单胞菌属、弧菌属、假单胞菌属、肠道杆菌科、黄杆菌属、邻单胞菌属、发光杆菌属、产碱杆菌属、短杆菌属、微球菌属、不动杆菌属、无色菌属。

A sort of lipase producing strain with relatively high esterification rate of ethyl hexanoate was obtained was isolated from Lavandula vera L. root soil. The strain was identified and named as Arthrobacter Y-605. The optimal lipase producing conditions of the strain was indicated in details and the results were as follows:2% maize meal, 1% soy flours, 0.1% urea, 0.05% MgSO4, 0.1% K2HPO4, 0.15% KCl.

以有机相中合成酶活为指标，通过对薰衣草根际土壤产脂肪酶菌株的筛选，获得了一株在有机相中合成己酸乙酯转化率相对较高的细菌Arthrobacter Y-605，其己酸乙酯转化率为67.53%。

A total of 13 bands were obtained and 6 of them (A1, A3, A4, A5, A9, A10) were sequenced. The sequences are similar to Leuconostoc mesenteroides (GenBank Access No.AY453065), some uncultured bacteria (AJ318147, AF227834, AJ576427), Ethanologenbacterium (AY434722), Clostridiaceae (AB084627), etc.

共得到13个可辨晰的SSCP条带，对其中的6条带(A1，A3，A4，A5，A9，A10)进行了测序分析，分别同嗜柠檬酸明串球菌(GenBank登录号：AY453065，下同)、未培养细菌(AJ318147，AF227834，AJ576427)、产乙醇杆菌(AY434722)、梭杆菌(AB084627)等相似性较大。

When pneumomediastinum and loculated pleural effusion are encountered on chest radiography, the possible origins of the air should include thoracic organ invasion by gas-forming bacteria.
