[Isolation of a high hydrogen-producing mutant TB34 generated by transposon insertion and analysis of hydrogen production].

To increase the hydrogen-producing capacity of Pantoea agglomerans BH18, isolated from mangrove sludge, we constructed a stable transposon mutagenesis library of this strain. A Tn7-based transposon was randomly inserted into the genomic DNA. Mutants were screened by kanamycin resistance and identified by amplification of the inserted transposon sequences.
