摘要：
"composition for the biological control of plant pathogens, process of their obtaining and their uses". The present invention has as its object the production of antagonistic microorganisms and metabolites in a liquid medium, economically compatible with agricultural production, dispensing the process of iron removal from the medium for the production of siderophores and other metabolites that potentiate the antagonist activity through the recovery. of the microorganism and the molecular complex formed during its growth, without the need for a separation step, and, optionally, its immobilization in an appropriate substrate to obtain compositions for biological control of phytopathogens. One embodiment of the invention relates to a composition containing siderophore producing microorganisms and other substrate immobilized metabolites preferably comprising earth, optionally in admixture with one or more agriculturally acceptable materials. A second alternative relates to a composition containing the metabolite producing microorganisms and a suitable carrier for use in the preservation of human and animal products against spoilage causing microorganisms. A third embodiment concerns a process for obtaining the biological control composition of phytopathogens characterized in that it does not require the removal of iron traces from the culture medium of the siderophore-producing microorganism as well as the isolation of cells and metabolites."composição para o controle biológico de fitopatógenos, processo de sua obtenção e seus usos". a presente invenção tem por objeto a produção de microrganismos antagonistas e metabólitos em meio líquido, economicamente compatível com a produção agrícola, dispensando o processo de remoção de ferro do meio para a produção de sideróforos e outros metabólitos que potencializam a atividade antagonista, através da recuperação do microrganismo e do complexo molecular formado durante seu crescimento, sem necessidade de etapa de separação, e,
