Abstract EN
Many studies have shown that several Greek ecosystems inhabit very interesting bacteria with biotechnological properties.
Therefore Streptomyces isolates from diverse Greek habitats were selected for their antifungal activity against the common phytopathogenic fungus Fusarium oxysporum.
The isolate encoded ACTA1551, member of Streptomyces genus, could strongly suppress the fungal growth when examined in antagonistic bioassays in vitro.
The isolate was found phylogenetically relative to Streptomyces rochei after analyzing its 16S rDNA sequence.
The influence of different environmental conditions, such as medium composition, temperature, and pH on the expression of the antifungal activity was thoroughly examined.
Streptomyces rochei ACTA1551 was able to protect tomato seeds from F.
oxysporum infection in vivo while it was shown to promote the growth of tomato plants when the pathogen was absent.
In an initial effort towards the elucidation of the biochemical and physiological nature of ACTA1551 antifungal activity, extracts from solid streptomycete cultures under antagonistic or/and not antagonistic conditions were concentrated and fractionated.
The metabolites involved in the antagonistic action of the isolate showed to be more than one and produced independently of the presence of the pathogen.
The above observations could support the application of Streptomyces rochei ACTA1551 as biocontrol agent against F.
oxysporum.
