Abstract:
Biotechnologically produced antifungal compounds for control of plant
diseases caused by phytopathogenic fungi represent a promising alternative
to synthetic pesticides. Fungi from the genera Alternaria and Fusarium are
listed among important storage pathogens of apple fruits. A. alternata
causes significant annual losses of apple fruit. Also, F. avenaceum is one
of the most commonly encountered Fusarium species identified as the causal
agent of a wet apple core rot. Species of the Streptomyces genera are soil
bacteria that produce significant quantities of bioactive compounds in
appropriate media. Defining the culture medium composition is the basis of
bioprocesses development. Nitrogen source is critical component of
cultivation medium and also the most useful tool for stimulation of the
antifungal metabolites production. The aim of this study was to select the
best nitrogen sources in medium for the production of antifungal compounds
effective against A. alternata and F. avenaceum by S. hygroscopicus.
Activity of the cultivation liquids on A. alternata and F. avenaceum
isolates was tested in vitro using well diffusion method. The results
in?dicate that maximum inhibition zone was reached in medium with soybean
meal as nitrogen source with inhibition diameter more than 35 mm for both
tested fungi.
