The extracting coenzyme Q_(10) from Blakeslea trispora using saponific ation was also studied by orthogonal test. And the optimum extracting conditions were obtained as follows: Wet culture was distilled at 70℃for 60min, added caustic potash up to 1.9 times of dry culture, pyrogallol up to 1/2 dry culture, and the concentration of alkali-methanol was 10%.The average recovery of CoQ_(10) was 81.5%.

The results showed that the bacteria B7 came into the logarithmic growth phase for 5 h culture. Both the fermentation liquid and its filtration could inhibit C. colhounii effectively, and the fermentation of dilution l0 times also showed significant differences compared with the control. The inhibiting effect of its fermentation media filtration was even more significant in the optimizing test, with the maximal inhibition rate of 100%. The best fermentation condition was 0.5% glucose, 0.1% ammonium muriate, without extra mineral, pH 5.4, temperature 28℃. Based on the morphological properties and 16S rRNA sequence, the bacterium B7 was identified as the Bacillus subtilis.

As known as traditional viewpoint, microbe could produce hydrogen continuously only when microbic cell is fixed, so present tests of this process offen adopt this process fixed-cell technology of pure microbe and were in the scale of batch fermentation test. Now the larggest ability of bio-producing hydrogen was 20mLH〓/g biomass·h produced by Rhodospirillum rubrum and 1. 6mLH〓/g biomass·h produced by Clostridium butyricum .
传统观点认为,微生物惟有进行细胞固定化才能达到持续产氢,所以现有试验常采用纯种细胞固定化技术,且尚处于分批培养试验阶段,最大产氢能力深红螺菌为20mLH〓/g菌体·h,丁酸梭状芽孢杆菌为1.6mLH〓/g菌体·h。

Results showed that, pyrolin had obvious action on two species of fungi, and the antifungal effect was positively correlative with concentration. The EC50 was 0.4076 mg/mL and 0.4626 mg/mL respectively after cultured 3 days. The main antifungal period was the fast growth period of fungi, and lead to it lag behind. Observation under SEM revealed that pyrolin caused a series of marked morphological and structural alterations of hyphal. These changes included mutual adhesion of mycelium, the hyphal was irregular in diameter, local denting, some of mycelium was broken, disruption of cell wall, outbreaking of inner cytoplast, and the empty cavity appeared. As a result, pyrolin restrained the growth of these fungi.
