Abstract

Pseudomonas aeruginosa PAO was able to grow in the absence of exogenous terminal electron acceptors, provided that the medium contained 30 to 40 mM L-arginine and 0.4% yeast extract. Under strictly anaerobic conditions (O2 at <1 ppm), growth could be measured as an increase in protein and proceeded in a non-exponential way; arginine was largely converted to ornithine but not entirely consumed at the end of growth. In the GasPak anaerobic jar (Becton Dickinson and Co.), the wild-type strain PAO1 grew on arginine-yeast extract medium in 3 to 5 days; mutants could be isolated that were unable to grow under these conditions. All mutants (except one) were defective in at least one of the three enzymes of the arginine deiminase pathway (arcA, arc...
