NOUVELLE SOUCHE STREPTOMYCES BARAKATEI, SES COMPOSES ACTIFS DERIVES ET LEUR UTILISATION DANS LE TRAITEMENT DES PLANTES

摘要

The subject matter of the invention is a new Streptomyces barakatei strain deposited with the CNCM under number I-3640 and with the LMG under number P-23734. The invention also relates to the use of this strain or of a mutant strain for obtaining a composition (culture filtrate) and active compounds (secondary metabolites) by fermentation. Finally, the invention also relates to the use of the new strain, of a mutant strain, of the culture filtrate or of the active compounds, for plant protection and the biological control of phytopathogenic agents and/or for stimulating plant growth.
