To analyze the antibacterial activity of culture supernatants of P. polymyxa strains and their extracts, 50 l of each sample was loaded onto a paper disk and transferred to the E. coli plates. Recombinant B. subtilis cells grown overnight in 3 ml of LB medium at 37C were inoculated directly onto the E. coli plates by dropping 5 l of the culture onto plates.
Herein, we review research on this species over the past two and a half decades, and focus on the mechanisms of P. polymyxa strain E681, isolated from barley roots in the Republic of Korea in 1995. Strain E681 has outstanding growth promoting effects on barley, cucumber, pepper, sesame, and Arabidopsis thaliana and produces antimicrobial compounds that protect plants against pathogenic
The characteristics of V. alginolyticus adhesion were found to correlate with its epidemiologic characteristics, 11, 12 and bacterial adhesion was found to be influenced by environmental factors such as temperature, pH and salinity, among others. 13 To explore the mechanisms by which environmental factors influence bacterial adhesion, pathogenic V. alginolyticus was subcultured under nine different

The adhesion behaviour of Paenibacillus polymyxa bacteria on pyrite and chalcopyrite is examined by the surface thermodynamics and the extended DLVO theory approaches.
Adhesion of bacteria onto solid surfaces is a necessary event in nature for the utilization of inorganic and organic values and for the enhanced growth of bacteria.
From adhesion tests, it is also clear that the above bacteria adsorb preferentially on hematite and corundum than on quartz. It is obvious from the interaction energy calculations that the columbic forces playa major role in the interaction of P. polymyxa with hematite. corundum and qUartz.
Paenibacillus polymyxa is a plant growth promoting rhizobacterium with a broad host range, but so far the use of this organism as a biocontrol agent has not been very efficient.
