[Bacterial interaction in a culture containing Pseudomonas and Mycobacterium in relation to hydrocarbon oxidation]. / Vzaimodeistvie bakterii v kul'ture, soderzhashchei Pseudomonas i Mycobacterium, v sviazi s okisleniem uglevodorodov.

An experimental association of Pseudomonas and Mycobacterium was employed for a more complete oxidation of a hydrocarbon substrate. The maximum effect of combined cultivation (74% vs. 50 and 47% in the pure cultures of Mycobacterium and Pseudomonas, respectively) was obtained under steady-state conditions. The result is attributed to the processes of co-oxidation and the physiological properties of the microorganisms.

[Role of emulsification in the process of hydrocarbon absorption by Pseudomonas aeruginosa cells]. / Rol' émul'girovaniia v protsesse pogloshcheniia uglevodorodov kletkami Pseudomonas aeruginosa.

Lipophilic biopolymers from the cell walls of saprophytic mycobacteria were shown to stimulate the process of hydrocarbon assimilation by Pseudomonas aeruginosa cells. This should be attributed to the fact that bacterial peptidoglycolipids emulsify a hydrocarbon facilitating the contact between it and the cells. It has been found experimentally that P. aeruginosa cells growing in the medium with n-alkanes release a factor into the medium. The factor appears to contain peptide chains and is responsible for hydrocarbon emulsification.
