Kinetic analysis for effect of initial substrate concentration on growth and secondary metabolite production in cultures of Nicotiana tabacum

Suspension cultures of tobacco cells were studied using airlift and rotary-drum bioreactors. The effect of initial concentrations of a major substrate, sucrose, on the growth and production of a secondary metabolite, phenolic compounds, was investigated. The dry weights and total concentrations of the phenolic compounds increased with the initial sucrose concentration in both bioreactors. Both bioreactors were found to have the same tendency for the effect of initial sucrose concentration. The structured model, presented previously was modified by considering that sucrose was hydrolyzed to glucose and fructose by an enzymatic reaction. The previous and the new models were applied to the above two sets of experimental data obtained with two bioreactors, independently. The hydrolysis of sucrose was elucidated to contribute slightly to the overall kinetics of growth and secondary metabolite production in these cultures. Furthermore, the levels of shear damage in each bioreactor were quantitatively compared based on the death rate constant, k_i, which is one of the model constants.     

被动锁模复合环形腔掺饵光纤激光器的自启动分析

本文对被动锁模复合环形腔掺饵光纤激光器的自启动工作特性进行了分析，指出谐振腔内残余反射面的存在是阻碍激光器实现自启动锁模的主要原因。利用半导体激光器有源区的折射率随注入电流的变化而改变的特性，在谐振腔中获得了一个可移动腔镜，克服了腔内残余反射面的影响，实现了锁模的自启动。
