Aspergillus niger 505 was treated with r ray and diethyl sulfate ( DES ) in the present study, and a strain A. niger UCD69 was obtained, which was superior to the parent by more than 3.7 times when glucose oxidase activity was concerned. The results showed DES was a more effective mutagen than r-ray in increasing the activity of glucose oxidase by A. niger.

Competitive utilization of CH2Cl2 and CH3OH by the preacclimated pseudomonas sp. strain DMI was studied in batch cultures. The degradation of CH2Cl2 by DMI was a process with severe substrate inhibition .The sim simulta- neous utilization of CH2Cl2 and CH3OH prompted the bacteria to enhance their growth rate. When the two substrates coexisted, DMI showed a preference of degrading methanol over dichloromethane.

Competitive utilization of CH2Cl2 and CH3OH by the preacclimated pseudomonas sp. strain DMI was studied in batch cultures. The degradation of CH2Cl2 by DMI was a process with severe substrate inhibition .The sim simulta- neous utilization of CH2Cl2 and CH3OH prompted the bacteria to enhance their growth rate. When the two substrates coexisted, DMI showed a preference of degrading methanol over dichloromethane. The specific consumption rate of each substrate was lower than that when either was used as the sole carbon and energy source. The competition of methanol of high concenttatinn inhibited noly CH2Cl2 biode- gradation capability for the CH2Cl2- preacclimated DM1, but also the induction rate of pehalo -genation activity for the CH3 OH-Preacclimated one. The relative rate of consumption the two subtrates was dependent on the bioactivity of the inoculum and the interacion of substrates.

用分批培养的方法研究了经CH2Cl2或CH3OH驯化的假单胞杆菌DMI对CH3OH和 CH2Cl2竞争性利用的动力学.CH2Cl2的降解过程是严重底物抑制过程,CH2Cl2和CH3OH 的同时利用有助于提高菌体的生长速率.两种底物共存时,甲醇的消耗占优势、同种底物比 的消耗速率均低于在单一碳源时的数值.高浓度甲醇的竞争作用不但抑制了CH2Cl2驯化的 DMI对CH2Cl2的降解能力,而且抑制了CH3OH驯化菌脱卤活性的诱导过程.两种底物消 耗的相对速率取决于接种物的生物活性和底物的相互作用.

The xanthan gum is the extracellular polysaccharide secreted by xanthomonas campestris from wild rape. It can be produced by fermentation with starch or glucose as the carbon source. Polysaccharide fermentation with starch as the carbon source at different levels of dissolved oxygen has been investigated. Experimental results showed that the dissolved oxygen has little influence on the fermentation of polysaccharide when its level exceeds 20% of air saturation. When the dissolved oxygen drops below 20% of air...

The xanthan gum is the extracellular polysaccharide secreted by xanthomonas campestris from wild rape. It can be produced by fermentation with starch or glucose as the carbon source. Polysaccharide fermentation with starch as the carbon source at different levels of dissolved oxygen has been investigated. Experimental results showed that the dissolved oxygen has little influence on the fermentation of polysaccharide when its level exceeds 20% of air saturation. When the dissolved oxygen drops below 20% of air saturation, it has greater influence on the growth of bacteria. The optimum value of dissolved oxygen for bacterium growth is 25% of air saturation.
