摘      要：Microorganisms experience intra-and inter-species interactions in the soil,and how these interactions affect the production of microbial volatile organic compounds(VOCs)is still not *** we evaluated the production and activity of microbial VOCs as driven by bacterial intra-species community *** set up bacterial communities of increasing biodiversity out of 1–4 strains each of the Gram-positive Bacillus and Gram-negative Pseudomonas *** evaluated the ability of each community to provide two VOCmediated services,pathogen suppression and plant-growth promotion and then correlated these services to the production of VOCs by each *** results showed that an increase in community richness from 1 to 4 strains of both genera increased VOC-mediated pathogen suppression and plant-growth promotion on agar medium and in the soil,which was positively correlated with the production of pathogen suppressing and plant growth-promoting *** strains maintained while Bacillus strains reduced community productivity with an increase in community richness and produced eight novel VOCs compared with the *** results revealed that intra-species interactions may vary between Gram-negative and Gram-positive species but improved VOC-mediated functioning with respect to pathogen suppression and plant-growth promotion by affecting the amount and diversity of produced VOCs potentially affecting plant disease outcomes.
