MORPHOLOGICAL, PHYSIOLOGICAL, AND BIOCHEMICAL-PROPERTIES OF THE PSEUDOMONAS-AERUGINOSA DISSOCIATION VARIANTS

Populations of the hydrocarbon-oxidizing strain K-2 of Pseudomonas aer uginosa dissociate into R, S, and M variants. They differ in colony mo rphology, cell fine structure, and cell yields on synthetic medium wit h hexadecane and on nutrient broth mixed with wort (NB+W). The best gr owth on NB+W was shown by the R variant, while the highest cell yield on hexadecane medium (exceeding that of the original culture) was atta ined by the S variant.
