In contrast, USA A. migulanus NCTC 7096 proved less effective for inhibition of plant pathogens. Nagano Maria Lurdes Inacio, Instituto Nacional de Investigação strain exerts biocontrol activity against some gram-positive and gram-negative bacteria, Agrária e Veterinária, Portugal fungi and oomycetes through the production of gramicidin S (GS). Apart from the *Correspondence: antibiotic effects, GS increases the rate of evaporation from the plant surface, reducing Lassaad Belbahri periods of surface wetness and thereby indirectly inhibiting spore germination.
