additional information
construction of A narB knockout mutant using a homologous recombination strategy. The DnarB strain produces 7times more H2 than the wild-type after 2 days of fermentation, while in the absence of nitrate, both DELTAnarB and wild-type produce the same amount of H2, as expected. The DELTAnarB strain cannot grow photoautotrophically on nitrate, but does grow on urea or ammonia. The DELTAnarB strain significantly redirects biomass accumulation into glycogen reserves at the expense of protein accumulation throughout growth. Phenotype, overview
