The mutants were further screened through repeated fermentations as well as the measurement of their physical properties. The results showed that some major fermentation indexes of strain HJ1615-d4 such as alcoholicity, fermenting power,total acids and flavoring components etc. were almost the same as those of the original strain. However, its urea yield was only 15.41 mg/L, louer 50 % than that of the original strain.

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.

Anaerobic synecology of the hydrogen-producing fermentation system was investigated under certain test condition in this thesis. In the continuous flow system of anaerobic hydrogen-producing fermentation, the succession of hydrogen-producing acidogenic microbiology may be regressive process. By regressive process we means that the original community getting from nature which structure being complex with a high ability would degenerate gently to a certain climax community which structure being simple with less ability.
