The important premise for hydrogen production technology of fermentation generator was to separate and identify the efficient hydrogen producing bacteria. By use of Hungater technology and flat-panel technology with wide-body narrow-neck flask, LM-1 and HPB-LR medium to separate and identify the anaerobic fermentation hydrogen production bacteria, and five hydrogen-producing bacteria were obtained, whose hydrogen metabolism was ethanol fermentation. The product analysis on the hydrogen production bacteria fermentation liquid showed that ethanol and acetic acid accounted for 95%-99% of the total metabolites. These strains can be fermented to produce hydrogen, and can be used for industrial applications.

Contrast Analysis

Biohydrogenbacterium R3 sp.nov, as a typical strains of hydrogen production bacteria, was isolated from the activated sludge in the biohydrogen production reaction by using culture media of HPB-LR which was designed particularly for isolating anaerobic fermentation bacteria and an improved Hungate rolling tubes technique and a plate method of culture bottle (PMCB) which were used for counting and isolating the anaerobes by our lab. Two representative strains of hydrogen production bacteria, namely RL20, RL37, and a strain of no hydrogen production bacterium, namely RL16 were used as contrast analysis. Experiment results indicated that the distributed proportion of ethanol and acetic acid was 95%-99% in the total amount of VAFs (Volatile Fatty Acid) of R3 which were typical ethanol-type fermentation, and the total amount of ethanol and acetic acid was commensurate with that of propionic acid.

ABSTRACT Thermotolerant microorganisms are useful for high-temperature fermentation. Several thermally adapted strains were previously obtained from Acetobacter pasteurianus in a nutrient-rich culture medium, while these adapted strains could not grow well at high temperature in the nutrient-poor practical culture medium, “rice moromi.” In this study, A. pasteurianus K-1034 originally capable of performing acetic acid fermentation in rice moromi was thermally adapted by experimental evolution using a “pseudo” rice moromi culture. The adapted strains thus obtained were confirmed to grow well in such the nutrient-poor media in flask or jar-fermentor culture up to 40 or 39 °C; the mutation sites of the strains were also determined. The high-temperature fermentation ability was also shown to be comparable with a low-nutrient adapted strain previously obtained. Using the practical fermentation system, “Acetofermenter,” acetic acid production was compared in the moromi culture; the results showed that the adapted strains efficiently perform practical vinegar production under high-temperature conditions.
