AIMS Cell survival and antagonistic activity against Listeria innocua, Listeria monocytogenes and Staphylococcus aureus were investigated after spray-drying three bacteriocin-producing strains of lactic acid bacteria: Carnobacterium divergens, Lactobacillus salivarius and Lactobacillus sakei. METHODS AND RESULTS Bacterial cell concentrates were spray-dried and stored at 4 degrees C and 18 deg...

in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...

The genome of Paenibacillus polymyxa Sb3-1, a strain that shows antagonistic activities against pathogenic fungi and bacteria, consists of one 5.6-Mb circular chromosome and two plasmids of 223 kb and 8 kb. The genome reveals several genes that potentially contribute to its antagonistic and plant growth promotion activity.

Two different synergy testing methods, the checkerboard and the E test methods, were used to compare the in vitro efficacies of various antimicrobial combinations against 16 Brucella melitensis strains isolated from blood cultures. The rate of agreement of the E test and checkerboard methods was found to be 55%. The most concordant results were found for the streptomycin-doxycycline combination...

Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...

The use of Trichoderma isolates with efficient antagonistic activity represents a potentially effective and alternative disease management strategy to replace health hazardous chemical control. In this context, twenty isolates were obtained from tomato rhizosphere and evaluated by their antagonistic activity against four fungal pathogens (Fusarium oxysporum f. sp. lycopersici, Alternaria altern...

backgoround: plant diseases, caused by a wide range of phytopathogenic fungi, could be managed using of trichoderma sp, as a biocontrol agent. cell wall degrading enzymes like chitinase from t. harzianum are important means for fungal pathogen inhibition. overexpression of these chitinase enzymes can improve the antagonistic potential of trichoderma sp. strains. objectives: this study aimed to ...
