title: [Morphologic and physiologic-biochemical characterization of Pseudomonas aeruginosa dissociation variants].
abstract: Populations of the hydrocarbon-oxidizing strain K-2 of Pseudomonas aeruginosa dissociate into R, S, and M variants. They differ in colony morphology, cell fine structure, and cell yields on synthetic medium with hexadecane and on nutrient broth mixed with wort (NB + W). The best growth on NB + W was shown by the R variant, while the highest cell yield on hexadecane medium (exceeding that of the original culture) was attained by the S variant.
