Wirkung des Detergens Metaupon auf die Vermehrung verschiedener Phagen

G. Menzel

E. Stenz

Abstract: As several other surfactants do, the detergent Metaupon acts on the multiplication of bacteriophages. We investigated the influence of Metaupon on the phages 0 105 and 1, the cyanophage LPP-1, and the RNA-phages f 2 , M 12, and QB by means of the agar diffusion test, pour plate test, adsorption test, and one-step growth test. The action of Metaupon on the free phages was also tested. Metaupon inhibits the formation of plaques by the phages with exception of 3,. With the phages f 2 and M 12 the substance increa… Show more

Inhibierung der Entwicklung von Bakteriophagen in Fermentationsprozessen durch Zusatz von Kohlenwasserstoffen

The propagation of the virulent phage M 1 of the obligate methylotrophic bacteria strain GB 4 is inhibited by n‐alkanes. The addition of hydrocarbons (7.5–22.5%) to a suspension of free phages or to a phage‐host‐mixture prevents the propagation of the phages, but does not influence the growth rate of the host bacteria. In a laboratory fermentor a simulated strong infection (multiplicity = 0.1) of the strain GB 4 with its phage M 1 could be suppressed by the application of 20% of a technical hydrocarbon mixture (Parex I).The inhibitory effect of the hydrocarbons can be traced back to inspecific hydrocarbon‐protein‐interactions at the surface of the phage and the host cells and therewith to an influencing of the adsorption.

Importance of bacteriophages in fermentation processes

Any bacterial strain can be infected by virulent phages or harbour one or more prophages. Therefore, bacteria-phage interactions are to be regarded as fundamental properties of bacteria. In current industrial fermentation processes phages can be advantageously employed for the identification of bacterial production strains (phage typing). In some cases phages are involved in the production of enzymes and special substances. The fundamental importance of phages in any technical fermentation process, however, is based on the peculiarities of their obligately parasitic life cycle. The propagation of phages in fermentation processes can cause complete (or a t least partial) lysis of the production strains and, consequently, serious disturbances in the production process and considerable economic losses. The phage problem in the fermentation industry has not yet been completely solved. For the protection of technical processes against virulent phages five measures are discussed: phage-protected sterile fermentation, employment. of alternative cultures, employment of phage-resistant mutants. employment of phage inhibitors, and employment of immobilized bacterial cells. The problem of the protection of bacterial production strains from prophage induction is more difficult and practically unsolved. Two possibilities to minimize the process risk due to temperate phages, the elimination of inducing factors during the fermentation process, and the selection of production strains which are difficult to induce, are discussed.

The effect of 21 surfactants on the plaque formation was tested in three RNA-phages/Escherichia coli systems and in one RNA-phage/Pseudomonas aeruginosa system. Especially anionic detergents proved to be able to influence the plaque formation substantially. In high concentrations of Metaupon, Fekunil 602, Fekunil S-BA, Emulgator W 270, and Emulgator O-BA the plaque formation by the phages M 12 and f2 was inhibited and in low concentrations it was promoted. In the system Q beta/E. coli AB 301 the effect of the detergents mentioned was restricted to the prevention of the appearance of plaques. The detergent E 30 brought about only plaque inhibitions, too, in all used RNA-phages/E. coli systems. The treatment with effective detergents in the system PP7/P. aeruginosa, however, increased only the number of plaques. This phenomenon was evident in the formation of radiate plaque patterns in the lawn of bacteria. In the case of RNA-phages of E. coli the formation of such trains of lysis depends on the choice of the nutritive medium. The addition of the detergent Fekunil 602 at different times after the contact between phages and host bacteria affects the length of the beams of lysis. The ionogenity of surfactants seems to be of importance for the formation of radiate plaque patterns, since the tested cationic compound and the nonionic surfactants, contrary to anionic surfactants, did not cause any beams of lysis.
