Abstract
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% (w/v) glucose. Other species of Pseudomonas studied varied in their utilization of these compounds, suggesting a different and possibly satisfactory approach to the identification and classification of species within the genus Pseudomonas.
