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。

82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.
轴向进料蒸发室进口管侧上方有强烈的循环流存在,循环流流量为进口流量的1.48~1.82倍;循环流下部流速分布较均匀,出口区流速在低Re时为抛物线分布,高Re时接近活塞流;强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发,而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发,对蒸发操作十分有利;蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。

Results:The cell aggregations had differences in shape as well as size, flavone content, enzyme activities, growth speed and so forth. The flavone content of the smallest cell aggregation was approximately twice compared to the larger ones, and its malonaldehyde content, the phenylalanine ammonialyase and peroxide enzyme activities and recultivate curve presented the same change tendency.
