  • Process for increasing biomass and spores production of plant growth promoting bacteria of the bacillus genus
    Patent number: 9839222
    Abstract: The present invention refers to a process designed to increase the production of plant growth-promoting microorganisms of the Bacillus genus, using a culture medium poor in nutrients and with specific environmental conditions, allowing to obtain a greater amount of biomass and/or spores, which can be used to prepare solid or liquid compositions to be applied to plants, aiming to promote their growth and/or counteract the effect of phytopathogenic agents.
    Type: Grant

  • PRODUCTION PROCESS FOR BIOMASS AND FENGYCIN METABOLITES OF BACILLUS SPECIES AND COMPOSITIONS THEREOF FOR BIOLOGICAL PEST CONTROL
    Publication number: 20160073642
    Abstract: The present invention refers to a process for increasing the production of biomass and metabolites of microorganisms of Bacillus sp. species. Obtained metabolites are lipopeptide compounds of the fengycin, surfactin, and iturin families, which exhibit antimicrobial activity. The invention further includes biocidal compositions comprising Bacillus subtilis EA-CB 0015, Bacillus amyloliquefaciens EA-CB0959, and/or metabolites thereof, either alone or together with other biocidal agents, and the use of these compositions for the treatment of diseases caused by various phytopathogenic agents, including Mycosphaerella fijiensis, in a variety of crops.
