第一种是细菌化学合成，即由细菌利用化学变化而形成的能量来产生食物；另一种是水平对流，即食材从周围地区飘移过来。

We also studied the effect of several solutions for producing zoosporangium in Artificial culture condition, the result shows the hyphea culture with 0.1% KNO3 produced the most quantity of zoosporangiums.

将这8株内生细菌与烟草黑胫病菌共培，进一步测定拮抗效果结果显示YN-55、NN-3、YN-4和YN-10 4株拮抗效果最好，均在66％以上，并且这4种细菌均对孢子囊的产生有较强的抑制作用，而菌株发酵液对孢子囊的产生的抑制作用不明显。

The biotransformations of isoeugenol to vanillin with various strains available in our lab were tested. It was found that several baterica including Bacillus subtilus 7658, Alcaligenes AS1.7617, Brevibacterium flavum 1.7a and Brevibacterium flavum AS1.013 could convert isoeugenol to vanillin.

对实验室所保藏的细菌、放线菌、真菌进行初步筛选发现细菌中枯草芽孢杆菌7658、粪产碱杆菌AS1.7617、黄色短杆菌1.7a、黄色短杆菌AS1.013能产生少量香草醛，最高浓度为0.31 g/L；放线菌中诺卡氏菌Nocardia sp。

D limonene was distributed among the culture flasks (200 mg/L). The flasks were incubated at 28oC on a rotary shaker (r/min=120) for 5 days. On completion, the culture broth were successively extracted with EtOAc. The extract was quantitatively measured by gas chromatography mass spectrometry analysis, The results showed that biocatalytic reactions were comprised of oxidation, including hydroxylation and ketonization which occurred at different positions of the D limonene, as well as hydrogenation, hydrolyzation, esterification and cyclic cleavage. These bacteria strains possess the distinctive biocatalytic capacities towards the D limonene. A series of terpenoids, including sesqui , di and tri terpernoids were also observed,which was accounted for D limonene had influence on the metabolites of marine bacteria.

以2216E为培养基，添加200mg/L的柠檬烯，在28℃，以120 r/min摇瓶培养5 d，用乙酸乙酯提取培养液，经GC MS分析其转化产物，结果显示，这些细菌能在柠檬烯的不同位置进行羟基化、羰基化等，并伴随有还原、水解、酯化、开环等反应，但转化能力和转化程度不同；在产物中，还检测到系列结构不同的其它萜类：包括倍半萜、二萜以及三萜等，这些萜类化合物的产生跟柠檬烯的加入有关，说明柠檬烯能影响细菌代谢产物的产生。

Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.

从119个菌株中分离筛选出了6株细菌和5株霉菌，它们可以在含有木质素的培养基上良好生长：细菌分类学鉴定结果为X1、X2和X3：假单胞菌属，X4和X5：黄单胞杆菌属，X6：枝动杆菌属；对6株细菌降解木质素性能进行了初步的研究，选定X2和X4为实验用菌种，两株菌适宜的生长温度为30℃，最适初始pH值为7；经紫外线照射诱变法处理，可使它们产生的三种木素分解酶活性均有明显的提高，细菌增长速率比诱变前明显提高。

By inoculated to tobacco plants, six strains could be re-isolated from the inoculated plants, indicating that they were endophytic bacteria in tobacco. Culture these eight bacteria and Phytophthora parasitica var. nicotianae together, the result showed four endophytic bacteria YN-55, NN-3, YN-4 and YN-10 have the best antagonistic effects.
