In this study, bacterial isolates C1-4-7, D2-4-6, and M1-4-11 from Antarctic soil were phenotypically genotypically characterized, their antibacterial spectrum that of cell-free culture supernatant investigated. Finally, the effect temperature medium on production antimicrobial compounds was The three bacteria identified as different strains genus Pseudomonas. multi-drug resistant to antibiotics. They exhibited patterns growth inhibition pathogenic bacteria. remarkable for inhibiting entire...
Cancer is the second leading cause of death in world and colorectal cancer only that has shown a sustained increase mortality last decade. In search for new chemotherapeutic agents against cancer, extremophilic microorganisms have to be potential source obtain molecules natural origin with selective cytotoxic action towards cells. this work we analyzed ability collection Antarctic soil bacteria, isolated on Collins Glacier from rhizosphere Deschampsia antarctica Desv plant, secrete capable...
The mononuclear cobalt (III) complex derived from 1,10-phenanthroline with lactose [Co(phen)2lactose]Cl2·3H2O (1) has been prepared and its properties have compared the sucrose [Co(Phen)2sucrose]Cl2·3H2O(2) without carbohydrate [Co(Phen)2Cl2]Cl·3H2O(3).
In this work, a novel chitosan-based polyelectrolyte complex (PEC) was prepared using chitosan as the cationic polyelectrolyte, while potassium salt of poly(maleic anhydride-alt-tetradecene) (PMA-14) served anionic counterpart. These PECs were used for encapsulation two nitroeugenol derivatives: 4-allyl-2-methoxy-6-nitrophenol (3) and 2-allyl-6-nitrophenol (4). The results confirm formation efficient active compounds. Encapsulation efficiency (EE) influenced by chemical structure compounds,...
Carotenoids are highly important in pigmentation, and its content farmed crustaceans fish correlates to their market value. These pigments also have a nutritional role aquaculture where they routinely added as marine animal food supplement ensure development health. However, there is little information about carotenoids obtained from Antarctic bacteria use for pigmentation improvement flesh quality aquaculture. This study identified produced by soil bacteria. The pigmented strain (CN7) was...
Introducción: El profesional en Enfermería favorece el crecimiento y desarrollo de los individuos, a través la promoción salud prevención enfermedad mediante educación problemas salud, tal como fenómeno violencia escolar. Este artículo tiene objetivo interpretar escolar docentes estudiantes cuarto quinto grado una Escuela Pública San Rafael Arriba Desamparados, 2014. Método: enfoque cualitativo descriptivo que permite implementación distintas técnicas recolección datos con fin establecer,...
Low fermentation temperatures are usually employed to obtain high-quality wines. This is especially interesting for white wine production since it prevents the loss of volatile compounds and a browning appearance; however, available fermentative yeasts do not tolerate low temperatures. Therefore, an place find new with cryotolerance Antarctic continent. From soil samples collected in Antarctica, 125 were isolated, which 25 exhibited activity at 10 °C. After fingerprinting assay, we...
La disminución sostenida de la disponibilidad nuevas moléculas antimicrobianas para el uso terapéutico en las últimas décadas y gran aumento microorganismos resistentes a estos compuestos hace necesario buscar sustancias con propiedades antimicrobianas. Los ambientes extremos, donde hay poca nutrientes, son escenarios propicios este tipo compuestos, ya que bacterias compiten entre sí otros organismos por posicionarse nicho ecológico secretan, asociado su metabolismo secundario, una serie...
