Biohydrogen technology has drawn much attention due to its many advantages. However, it is still necessary to screen much more strains with stronger hydrogen-producing capacity for future commercialization processes. In this paper, a biohydrogen-producing strain Enterobacter aerogenes EB-06 was isolated, identified, and named. It could convert glycerol to biohydrogen by microorganism fermentation. The effects of oxygen content, initial pH, initial glycerol concentration, and initial nitrogen
... initial nitrogen source content on biohydrogen production process were investigated. The results have shown that biohydrogen generation was more favorable under anaerobic conditions. The optimum specific biohydrogen production rate (Q H2 ) was obtained as 41.47 mmol H 2 /g DCW h at 40 g/L initial glycerol concentration. The optimum volume H 2 yield (C H2 ) was 83.76 mmol H 2 /L at initial pH 7.0. It was found that nitrogen source content (0-4 g/L) could promote biohydrogen production and cell growth. The biohydrogen production of Enterobacter aerogenes EB-06 from glycerol was optimized by the orthogonal experimental design. The optimal yield coefficient of biohydrogen from glycerol fermentation (Y H2/glycerol ) of EB-06 was obtained as 1.07 mmol H 2 / mol glycerol at 10 g/L initial glycerol concentration, initial pH 5.0, and initial C/N ratio 5/3. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
