Catabolism of Nitrogenous Compounds by Pseudomonas [PDF]

Journal of General Microbiology, 1962
SUMMARY: The rate of O2 utilization by both pigmented and non-pigmented strains of Pseudomonas aeruginosa was greater with 2 % (w/v) Casitone as substrate than with 0.1 M-glucose as substrate. P. aeruginosa readily catabolized Casitone, amino acids and other nitrogenous compounds with the production of an alkaline reaction even in the presence of 0.5% (
