It appeared that, although the physicochemical cultivation conditions permitted the growth and survival of FB, it decreased in abundance in the mixed continuous cultures at a high rate (as judged from the rapid decrease in the parathion-hydrolyzing capacity of the bacterial cells from the mixed cultures) irrespective of the macroelement limiting bacterial growth.

看起来那，虽然物理化学的耕种条件允许了FB 成长和生存，它减少了在丰盈在混杂的连续的文化以一种高速率(依照被判断从在细菌细胞的对硫酮水解的容量的迅速减退从混杂的文化)不问macroelement 限制细菌成长。

Losing competence might affect their β-lactam resistance, and the consequences were different in different strains.4. To further understanding when and where pneumococci formed transformation in vivo so as to study the influence of pneumococcal transformation to its virulence, we constructed a pneumococcus 22G itstransformation forming could be reported by EGFP.

The main results are: construction of Tarim desert highway shelter-forest promoted soil microbial development, and with increase of plantation time of the shelter-forest, the quantity, fatty acid diversity index of soil microbe and diversity index of bacterial DNA segment enhanced notably. As to soil microbial community structure, bacteria are dominant population with amounting for over 80% of total soil microbe, and fungi is not more than 1% of total soil microbe, but soil microbial community structure was different among three soil layers. The conclusions from study methods of conventional culture, biological marker and molecule biology were almost identical, which illuminates that construction of Tarim desert highway made soil microbial activity enhance and so promote nutrient cycle and utilization of Tarim desert highway shelter-forest land.

结果表明，塔里木沙漠公路防护林的建设促进了风沙土土壤微生物的发育，随着防护林定植年限的增加，土壤微生物数量、脂肪酸和细菌DNA片段的多样性指数明显增大；土壤微生物区系组成中，细菌是优势类群，占微生物总数80%以上，而真菌很少，不到微生物总数1%，但在不同土层间有所差异；传统培养法与现代生物标记和分子生物学方法对塔里木沙漠公路防护林地土壤微生物多样性的研究结果基本一致，说明塔里木沙漠公路防护林的建设使林地土壤生物活性有所增强，有利于林地土壤养分循环与利用。

本试验采用稀释培养计数法对湿地附近水中微生物的数量变化动态进行计数调查，最后用最大可能数法求出单位体积水样中硝化细菌、反硝化细菌和氨化细菌三类微生物的数量。根据最终数据分析得到的结论是：在人工湿地附近的水中氨化细菌、硝化细菌、反硝化细菌的数量是最多的。

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。
