Rapid eradication of bacterial phytopathogens by atmospheric pressure glow discharge generated in contact with a flowing liquid cathode( )

Abstract: Diseases caused by phytopathogenic bacteria are responsible for significant economic losses, and these bacteria spread through diverse pathways including waterways and industrial wastes. It is therefore of high interest to develop potent methods for their eradication. Here, antibacterial properties of direct current atmospheric pressure glow discharge (dc‐APGD) generated in contact with flowing bacterial suspensions were examined against five species of phytopathogens. Complete eradication of Clavibacter michiganensis subsp. sepedonicus, Dickeya solani, and Xanthomonas campestris pv. campestris from suspensions of OD600  ≈ 0.1 was observed, while there was at least 3.43 logarithmic reduction in population densities of Pectobacterium atrosepticum and Pectobacterium carotovorum subsp. carotovorum . Analysis of plasma‐chemical parameters of the dc‐APGD system revealed its high rotational temperatures of 2, 300 ± 100 K and 4, 200 ± 200 K, as measured from N2 and OH molecular bands, respectively, electron temperature of 6, 050 ± 400 K, vibrational temperature of 4000 ± 300 K, and high electron number density of 1.1 × 10 15  cm −1 . In addition, plasma treatment led to formation of numerous reactive species and states in the treated liquid, including reactive nitrogen and oxygen species such as NOx, NH, H2 O2, O2, O, and OH. Further examination revealed that bactericidal activity of dc‐APGD was primarily due to presence of these reactive species as well as to UVA, UVB, and UVC irradiation generated by the dc‐APGD source. Plasma treatment also resulted in an increase in temperature (from 24.2 to 40.2 °C) and pH (from 6.0 to 10.8) of bacterial suspensions, although these changes had minor effects on cell viability. All results suggest that the newly developed dc‐APGD‐based system can be successfully implemented as a simple, rapid, efficient, and cost‐effective disinfection method for liquids originating from different industrial and agricultural settings. Abstract : A simple, rapid, efficient, and cost‐effective liquid sterilization method based on direct current atmospheric pressure glow discharge generated in contact with flowing suspensions of most important bacterial phytopathogens has been developed and evaluated. Due to generation of ROS, RNS, and UV irradiation, complete eradication of Clavibacter michiganensis, Dickeya solani, and Xanthomonas campestris was observed. In case of Pectobacterium atrosepticum and Pectobacterium carotovorum, at least 3.43 log reduction was achieved. Subsequent industrial and agricultural applications of herein reported system are prognosticated

Caractérisation moléculaire des signaux de sécrétion des protéines sécrétées par le système de sécrétion de type II de la bactérie phytopathogène Dickeya dadantii by Natalia Guschinskaya( )

The type II secretion system (T2SS) transports folded proteins from the periplasm through the outer membrane into the milieu. In many pathogenic Gram-negative bacteria, the T2SS secretes various virulence factors in host tissue and is directly involved in pathogenesis. The phytopathogen Dickeya dadantii secretes a dozen of pectinases through a T2SS named Out. The secreted proteins are lacking an obvious common signal and secretion is thought to involve multiple transient interactions of folded exoproteins with several T2SS components. Molecular nature of these interactions remains unknown. To address this question we used an in vivo sitespecific photo-crosslinking approach to capture such transient interactions within the functional T2SS of D. dadantii. In this technique, the photo-crosslinker para-benzoyl-L-phenylalanine, pBpa, is introduced in vivo in place of a residue of interest and UV-irradiation of living cells provokes the formation of complexes between the protein of interest and its partners. First, in a systematic approach, pBpa was introduced at several surface-exposed sites of the secreted protein PelI. This strategy permitted us to identify that one structural element, loop 3 of Fn3 domain in PelI, interacts both with the secretin, the outer membrane T2SS component, and with the PDZ domain of OutC, an inner membrane T2SS component. These results suggest that this loop 3 is a part of the secretion motif. The same approach permitted us to identify two other regions of PelI interacting with the T2SS: a linker situated between the two domains of PelI, which interacts with OutD, and an exposed region of the catalytic domain of PelI interacting with OutC. In another approach, pBpa was introduced into the T2SS components, OutC and OutD. These experiments suggested that the PDZ domain of OutC interacts with the secreted protein PelB. This study, in complement with other approaches, allowed us to uncover some important molecular features of the protein secretion by the T2SS
