Biological activity of some bacterial isolates against soil borne pathogenic fungi
نویسنده
چکیده
The antagonistic activity of three bacterial isolates namely Microbacterium terregens, Cellulosimicrobium cellulans and Bacillus amylollquefaciens was evaluated through direct confrontation method and filtrates culture against the growth of Fusarium solani, Fusarium oxysporum, Rhizoctonia solani and Phytophthra cactorum. All bacterial isolates showed the inhibition of the mycelia growth of the isolated fungi as resulting to confrontation methods except R. solani with C. cellulans that showed no inhibitory effect and energized the low activity with B. amylollquefaciens. Culture filtrate of different bacterial isolates after different incubation periods revealed that the highest antifungal activity between 3-10 days.

Actinomycetes are a source of a broad variety of secondary metabolites with diverse biological activities, such as antifungi, antibiotics and antitumorals; many of which have been developed for clinical use. In this study, 34 actinomycetes from untouched soils were isolated from Alborz Province-Iran. Evaluation ofantifungal and anti bacterial activities of these isolates, demonstrated the capab...

Prevalent fungal pathogens of cereals in Lithuania belong to diverse systematic groups and this makes search for microbial biocontrol measures rather difficult. One of the options would be broad-spectrum biocontrol agents. In order to find these, 1037 seed-borne and 11 soil-borne rhizosphere pathogenic fungi were isolated and their systematic position determined. Fungi of genera Alternaria, Ulo...

Screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. Actinomycetes have the capability to synthesize manydifferent antibiotics. A total of 69 actinomycete isolates were recovered from soil samplescollected from Alborz Province. Selected colonies (rough, chalky) of actinomycetes werepurified. All screened isolates were iden...

In vitro studies with Trichoderma spp., soil-borne fungal antagonists, demonstrated that a number of isolates produced volatile and non-volatile metabolites capable of inhibiting the growth and sporulation of several soil-borne plant pathogenic fungi. Microscopic observations showed that T. harzianm and T. viride, isolated from soil samples from Ahwaz and Karaj, adversely affected the myce...

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...
