### Effect of VOCs on Fungal Mycelial Growth  
The results of the tests carried out to evaluate the antagonistic capacity of the bacterial strains on the growth of studied pathogenic fungi via the production of volatile organic compounds are shown in Table 2. Strain UM270 caused significant inhibition of the pathogen _Alternaria alterata_, one of the main pathogens causing disease in blueberry fruits.
