Detecção de bacteriocinas produzidas por bactérias fitopatogênicas dos gêneros Erwinia, Pseudomonas e Xanthomonas

Abstract: A detecção da produção de bacteriocinas foi estudada em diferentes condições, utilizando-se linhagens de bactérias fitopatogênicas dos gêneros Erwinia, Pseudomonas e Xanthomonas. Obtiveram-se, respectivamente, 58,06%, 71,31% e 40,00% de linhagens produtoras no meio 523, que foi o mais indicado para detecção dessa produção. Uma maior concentração de ágar adicionada ao meio (1,5%) produziu melhores resultados mas, a quantidade de meio nas placas não influenciou a detecção de bacteriocinas. O maior tempo de incub… Show more

“…As a result, the diffusion method in liquid medium proved to be better compared to the solid medium "plugs", this can be explained by the sum of the set of all metabolites present in the medium acting synergistically as; lactic acid, acetic acid, hydrogen peroxide and bacteriocin. On the other hand, in the solid medium, a longer incubation time compared to the liquid medium may have enhanced the conditions for the growth and activity of other strains, although with the formation of a smaller zone of inhibition, suggesting the activity of only the bacteriocin (Biagi & Azevedo, 1992;Çadirci & Çitak, 2005).…”

“…citri strains FDC-585, FDC-625, FDC-601, FDC-011, and 14002 (Table 3 and Figure 2). The production of bacteriocins by the genus Xanthomonas that inhibit the growth of another pathovar is a common phenomenon (2,6,13,15), as demonstrated by the sensitivity of most X. axonopodis pv. citri strains to bacteriocins produced by strains of X. axonopodis pv.…”
