Bacterial spot and early blight biocontrol by epiphytic bacteria in tomato plants. Repositório Alice
LANNA FILHO, R.; ROMEIRO, R. da S.; ALVES, E..
Abstract ? The objective of this work was to evaluate in vitro and in vivo biocontrol of Xanthomonas vesicatoria) Alternaria solani) by the epiphytic bacteria Paenibacillus macerans and Bacillus pumilus. Tomato plants were previously sprayed with epiphytic bacteria, benzalkonium chloride and PBS buffer and, after four days, they were inoculated with A. solani and X. vesicatoria. To determine the phytopathogenic bacteria population, leaflet samples were collected from each treatment every 24 hours, for seven days, and plated on semi-selective medium. The effect of epiphytic bacteria over phytopathogens was performed by the antibiosis test and antagonistic activity measured by inhibition zone diameter. The epiphytic and benzalkonium chloride drastically...

Bioprospecting biofilm-forming epiphytic bacteria from wheat under oligotrophic conditions. Repositório Alice
CASTELIANI, A. G. B.; KAVAMURA, V. N.; MORAIS, J. F. A.; SILVA, J. L. da; PANSA, C. C.; MELO, I. S. de.
Abstract: Naturally occurring epiphytic microorganisms display different colonization strategies. Studies report their potential in acting as biocontrol agents through several mechanisms such as competition for space and nutrients, production of antibiotics, resistance induction, parasitism, among others. However, little is known about the mechanisms that could possibly act in the control of the pathogenic fungus Magnaporthe grisea, responsible for wheat blast. Thus, the present work aimed the selection of epiphytic bacteria with the potential to act as biological control agents against M. grisea through different mechanisms of action. Bacterial isolates were subjected to direct antagonism tests. The growth rate in oligotrophic conditions (1% sucrose and...
