Two kinds of specially designed shake flask was prepared, which can be used for monitoring some important parameters, shch as dissolved oxygen ( DO ), oxygen up take rate ( OUR ), carbon dioxide evolution rate ( CER ), respiration quotient ( RQ ) and volumetric oxygen coefficient ( K La) during the course of cell cultivation or fermentation. So, the optimized results from these kinds of shake flasks can be effectively used for translating the laboratorial data onto fermentor or other kinds of bioreactor. According to the data obtained from 4 cases (cultivation of brewing yeast, ATP production from AR by catalization of brewing yeast, cultivation of a recombinant E.coli to produce bFGF and Reduction of acetyl acetic ester to (S) 3 hydroxy acetoxy butanoic acid by a carbonyl reductase with in baker′s yeast) in specially designed flasks, we have successfully translated them to small scale fermentor or bioreactor with the same profile of key parameters as shake flasks and same yield have been obtained. It seems that the key parameter(s) for pure aerobic cultivation is OUR or DO ; for pure anaerobic cultivation or bioconversion CER ; for rather complicated bioprocesses, such as multi stage fermentations or bioconversion processes, even some recombinant microbial cultivations should be both OUR and CER or RQ . It seems also that the parameter K La is not so important for process translation, but an aerobic fermentor still needs to be equipped with enough capacity of oxygen supply to avoid oxygen depletion when the fermentation reaches the peak value of OUR . Generally, we believe that to maintain same profile of key physiological and biochemical parameters is very important for bioprocess translation, as well as for bioreactor scale up.

锥形摇瓶是实验室广泛使用的培养微生物的器皿,这是因为其结构简单、操作方便,且在同一摇床上进行多种并行试验以满足菌种筛选、培养基成分优化、培养过程的周期和需氧程度的定性推测等要求。但摇瓶在结构上和供氧与气液传递的方法方式上与实验室或生产上用的生物反应器有很大的不同,且一般不能在培养过程中取样和补料,限制了它的应用并且难以将摇瓶的研究结果转移到生物反应器中或用于发酵罐的放大。为此,我们研制了两种可在线检测某些能反映微生物过程中物质传递和代谢的特制摇瓶,以期能克服一般摇瓶不足之处。其中Ⅰ型摇瓶能检测培养过程中的溶氧、摄氧率、氧传递系数,Ⅱ型摇瓶除了能检测上述3个参数外,还能检测CO2释放率和呼吸商,两者都能进行取样和补料。文中还介绍了利用特制摇瓶测得的摇瓶口过滤介质的氧通透率和对4种具体过程,即啤酒酵母的培养、固定化酵母将AR转化为ATP、rbFGF大肠埃希氏菌的培养和面包酵母将乙酰乙酸乙酯转化为[S]-3羟基丁酸乙酯的摇瓶和小生物反应器的对照试验。试验的结果初步认为:在氧敏感的纯培养中,OUR或DO是关键参数;在厌气过程中CER是关键参数;在次级代谢产物的发酵、微生物转化及某些重组菌的培养中,OUR和CER或R?

Variation of phenolic acids during decomposition of some organic materials was studied by means of moist and aerobic cultivation. The results show that rice straw, pig feces and sawdust contain some kinds of phenolic acids such as p hydroxybenzoic acid, p coumaric acid and frulic acid. The contents of p coumaric acid in rice straw and pig feces are the highest, and followed by that of frulic acid. The content of p hydroxybenzoic acid in sawdust is the highest, followed by that of p coumaric acid. During decomposition, the main kinds of phenolic acid in rice straw and pig faces are p coumaric and frulic acids while in sawdust p hydroxybenzoic and p coumaric acids. The total phenolic acid contents are in a decreasing order, rice straw, pig feces, and sawdust. The total phenolic acid contained in the three organic materials reached the maximum after 20~30 days of decomposition, and reached a stable and minimum state after 40~50 days.\;
