Effect of static magnetic field (200 mT) on biofilm formation in Pseudomonas aeruginosa.

abstract：:The main property of an Amt- (ammonium transport negative) mutant of Klebsiella pneumoniae is its inability to accumulate NH4+ intracellularly. When growing on nitrogen sources other than NH4+, the mutant constantly looses NH3 by diffusion. This loss results in poor growth. The NH3 excretion suggests the existence of ...
