[Electrophoretic differences in the proteins of the species Pseudomonas aeruginosa and Pseudomonas denitrificans capable of oxidizing n-alkanes].
Pseudomonas aeruginosa and Ps. denitrificans are capable of growing on n-alkanes, but differ in assimilation of higher and lower alkanes. The proteins of their cell-free homogenates were analysed by disc-electrophoresis in a system containing SDS. The "preliminarily adapted" strain of Ps. aeruginosa did not differ from the "non-adapted" to n-hexane strain, though both differed considerably from Ps. denitrificans in the composition of protein spectrum. Therefore, disc-electrophoresis of total proteins has shown that Ps. aeruginosa and Ps. denitrificans are not genetically identical; they exhibit certain common physiological properties, but apparently oxidize n-alkanes via different pathways.
