Mutants of the cyanobacterium anabaena sp. PCC 7120 altered in nitrate transport and reduction

abstract：:Gram-negative bacteria are generally more tolerant to disinfectants than Gram-positive bacteria due to outer membrane (OM) barrier, but the tolerant mechanism is not well characterized. We have utilized comparative proteomic methodologies to characterize the OM proteins of E. coli K-12 K99+ in response to phenol stres...
