Production of ammonia as a low-cost and long-distance antibiotic strategy by Streptomyces species

摘要

Bioactivity and metabolomic analysis of VCs released by streptomycetes. a Bioactivity of VCs released by selected Streptomyces strains against E. coli strain ASD19. b Volatile antibiotic activity of different Streptomyces strains grown at pH 7 or pH10, the latter by addition of a glycine/NaOH buffer; E. coli strain ASD19 was the indicator strain. c Comparison of GC-chromatogram of VCs from bioactive and non-bioactive strains. d PCA-2D Plot showing the VC-grouping of the different strains. No clear separation between VCs produced by different Streptomyces strains is seen
