ABSTRACT : Microalgae are photosynthetic microorganisms widely used at the industrial level because of their high content of compounds with bioactive properties such as antimicrobial peptides. These compounds have a wide range of action mechanisms, do not produce the resistance of conventional antibiotics and could be effective against bacteria, fungi, viruses, parasites, and even tumor cells. In this work, by mechanical cell lysis treatment, a protein extract of dry biomass of Nannochloropsis sp was obtained, subsequently, it was hydrolyzed with an enzyme complex of proteases, papain, and pancreatin, for 6 hours, at 44 ° C and pH 7. Finally, the antimicrobial activity of the fraction of hydrolyzed extract with a size less than 3 kDa was evaluated against Staphylococcus aureus, Escherichia coli, and Candida albicans, obtaining a percentage of growth inhibition of 93.1%, 96.6%, and 14.4% respectively, which represents a peptic extract with bacteriostatic and fungistatic properties. |

Estos compuestos son eficaces contra bacterias, hongos, virus, parásitos e incluso células tumorales, poseen una amplia variedad de mecanismos de acción y no generan la resistencia de los antibióticos convencionales. En este trabajo, a través de lisis celular mecánica, se obtuvo un extracto de proteínas a partir de biomasa seca de Nannochloropsis sp., posteriormente fue hidrolizado usando un complejo enzimático de proteasas, papaína y pancreatina, durante 6 horas, a 44°C y pH 7. Finalmente, se evaluó la actividad antimicrobiana de la fracción de extracto hidrolizado que poseía un tamaño menor a 3 kDa contra Staphylococcus aureus, Escherichia coli y Candida albicans, obteniendo un porcentaje de inhibición de crecimiento de los microorganismos de 93,1%, 96,6%, y 14,4% respectivamente, lo cual representa un extracto peptídico con propiedades bacteriostáticas y fungistáticas.COL0066991COL00150997application/pdfengUniversidad Nacional de Colombia, Facultad de Minas, Centro de PublicacionesMedellín, Colombiahttps://creativecommons.org/licenses/by-nc-nd/4.0/http://creativecommons.org/licenses/by-nc-nd/2.5/co/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Antimicrobial potential of a hydrolyzed protein extract of the microalgae Nannochloropsis sp.Potencial antimicrobiano de un extracto de proteína hidrolizado de la microalga Nannochloropsis sp.Artículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionHidrólisisHydrolysisProductos con Acción AntimicrobianaProducts with Antimicrobial Actionmicroalgal proteinNannochloropsis sp.Proteína microalgalDyna19821119286DynaPublicationORIGINALVerdugoLucia_2019_Antimicrobial_Potential_Hydrolyzed.pdfVerdugoLucia_2019_Antimicrobial_Potential_Hydrolyzed.pdfArtículo de investigaciónapplication/pdf1978527https://bibliotecadigital.udea.edu.co/bitstreams/a2557a04-7c74-4f32-907a-c2bf5d6382c1/download2ac56d48781b53ccead577d67e8509ceMD51trueAnonymousREADCC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;
