PROCESS FOR PREPARING A BACTERIAL PRODUCT WITH ANTIFUNGAL EFFECT
The invention relates to a process for preparing a bacterial product with antifungal activity of the Bacillus amylolichefaciens culture, by developing the inoculum by cultivating the microbial strain on a glucose- and mineral salts-containing medium, for 24...36 hours, at a temperature of 28...32°C,...

description | The invention relates to a process for preparing a bacterial product with antifungal activity of the Bacillus amylolichefaciens culture, by developing the inoculum by cultivating the microbial strain on a glucose- and mineral salts-containing medium, for 24...36 hours, at a temperature of 28...32°C, while stirring at 160...200 rpm, obtaining the bioprocess culture by cultivating the microbial strain on a glucose- and mineral salts-containing medium, for 72...120 hours, at 28...32°C, while stirring at 160...200 rpm, separating the bacterial biomass by centrifugation at 4000 rpm and a temperature of 4°C, adjusting the supernatant pH to 2.5...3.5, extracting it twice with ethyl acetate at a supernatant : solvent volume ratio of 1 : 2.5, evaporating the solvent at 40°C for 20...30 min, solubilizing the residue in distilled water and conditioning the microbial metabolites as emulsion, by encapsulation in natural polymer particles.
Prezenta invenţie se referă la un procedeu de obţinere a unui produs bacterian cu activitate antifungică, din cultura de Bacillus amylolichefaciens, prin dezvoltarea inoculului cultivând tulpina microbiană pe un mediu conţinând glucoză şi săruri minerale, timp de 24...36 h, la 28...32°C, sub agitare la 160...200 rpm, obţinerea culturii de bioproces prin cultivarea inoculului pe un mediu conţinând glucoză şi săruri minerale, timp de 72...120 h, la 28...32°C, sub agitare la 160...200 rpm, separarea biomasei bacteriene prin centrifugarea la 4000 rpm şi la 4°C, ajustareaH-ului supernatantului la 2,5...3,5, extragerea de două ori a acestuia cu acetat de etil, la un raport în volume supernatant : solvent de 1 : 2,5, evaporarea solventului la 40°C, timp de 20...30 min, solubilizarea reziduului în apă distilată şi condiţionarea metaboliţilor microbieni sub formă de emulsie prin încapsulare în particule de polimer natural. |
