摘要	Pantoea agglomerans BH18, isolated from mangrove sludge, could produce hydrogen under marine culture condition. To improve the hydrogen-producing capacity of this strain, we constructed a stable transposon-mutagenized library of P. agglomerans BH18. A Tn7-based transposon was randomly inserted into genomic DNA of P. agglomerans BH18. Mutants were identified by kanamycin resistance and amplification of the inserted transposon sequences. A transposon mutant, named as strain TB212, was screened for the highest hydrogen production ability. The total volume of hydrogen gas evolved by this mutant strain TB212 was 60% higher than that of the wild type. The mutant strain TB212 was able to produce hydrogen over a wide range of initial pH from 5.0 to 10.0, with an optimum initial pH of 7.0, and hydrogen production was 2.52 +/- 0.02 mol H-2/mol glucose (mean +/- SE.) under marine culture condition. The mutant strain TB212 could produce hydrogen at the salt concentration from 3 to 6%. It was concluded that the transposon-mutagenized library may be a useful tool for investigation of high efficiency hydrogen-producing bacteria. Copyright (C) 2012, Hydrogen Energy Publications, LLC.
