El objetivo de este estudio fue determinar antagonismo in vitro hacia P. su efecto frutos limón persa. Se evaluó sobre levaduras. determinó por confrontación entre levadura-fitopatógeno competencia c...

Bacteria are able to synthesis a wide range of metabolites with fungicidal capabilities. The antagonistic potential of soil bacterial strains (E. coli, Baccillus fortis, B. faragiris, Pseudomonas flourescence and P. malophilia) was assessed by the dual culture technique against some food pathogenic fungi, i.e. Aspergillus flavus, A. niger, Penicillium italicum and P. simplicissmum. The result i...

Catechol and pyrogallol are allelochemicals which belong to phenolic compounds synthesized in plants. Their antimicrobial activities were investigated on three bacteria (Pseudomonas putida, Pseudomonas pyocyanea, Corynebacterium xerosis) and two fungi (Fusarium oxysporum, Penicillium italicum) phytopathogenic species as test organisms using the disc diffusion method. Both catechol and pyrogallo...
