Copper nanoparticles (CuNPs) functionalized with polyethyleneimine (PEI) and 4-aminobutyric acid (GABA) were used to obtain composites isotactic polypropylene (iPP). The iPP/CuNPs prepared at copper concentrations of 0.25–5.0 wt % by melt mixing, no evidence oxidation the CuNP was observed. Furthermore, release ions from in an aqueous medium studied. cupric higher 2.5 5.0 %. These showed excellent antibacterial activity (AA) toward Pseudomona aeruginosa (P. aeruginosa) Staphylococcus aureus...
Members of Agave L. utilize CAM. To date, research on the physiological and morphological adaptations has analyzed only a few species. With aim understanding basic aspects responses polyploid (2n = 2x 60 to 2n 6x 180) accessions in association with CO2 fixation, we carried out genetic studies A. tequilana Weber, fourcroydes Lem., angustifolia Haw., which are adapted two ecoregions Yucatán Mexico: Regional Roger Orellana-CICY Botanical Garden (RO-CICY) city Merida Germplasm Bank...
Abstract The present study provides antibacterial and thermal improvements of chitosan‐based systems through chemical modification with different quaternary ammonium salts using 1‐ethyl‐3‐(3‐dimethylaminopropyl) carbodiimide (EDC) as mediator. Three a carboxylic acid end group are synthesized quaternization reaction between bromohexanoic the respective tertiary amines (quinoline, N , ‐dimethylbenzylamine pyridine). They then chemically grafted along chitosan backbone EDC carboxyl activating...
Mentha piperita L., is one of the most popular and consumed species worldwide because its secondary metabolites with antioxidant properties, among these are polyphenolic molecules. These molecules can be extracted using different methodologies. However, range bioactive compounds in an extract vary factors, including extraction methodology. Recently, use hybrid technologies for plant has been increased since a empowerment various properties obtained extracts demonstrated. In this study was...
Abstract A new starch derivative with antibacterial properties and non‐hemolytic effect was synthesized through the chemical grafting of 4‐chloroaniline onto backbone potato starch. In a first step, extracted from potatoes grown in region Coahuila, Mexico, using water steeping method. The hydroxyl groups (C5‐C6) native were oxidized sodium periodate. resulting dialdehyde then chemically modified Schiff base reaction 4‐chloroaniline. structure this confirmed by Fourier transform infrared 1 H...
The incidence of antibiotics and transcriptional regulation ARGs in isolated bacteria from wastewater needs to be explored. By HPLC, samples untreated wastewater, ampicillin (49.74 ± 5.70 µg/mL), chloramphenicol (0.60 0.03 tylosin (72.95 2.03 oxytetracycline (0.22 0.01 µg/mL) was determined. Through metagenomic analysis identified 58 bacterial species belonging 9 phyla at least 14 have shown resistance a variety antibiotics. Twenty-two isolates were proved resistant fifteen new generation...
Abstract Three novel polyaspartate derivatives with antibacterial properties and low hemolytic effects are synthesized by the reaction of sodium (PAspNa) different quaternary ammonium salts a carboxylic end‐group, subsequently these tested in vitro against cancer normal cell lines. 1‐(carboxypentyl) pyridinium bromide, benzalkonium quinolinium bromide from quaternization between 6‐bromohexanoic acid respective tertiary amines (pyridine, N,N‐dimethylbenzylamine, quinoline). Then, chemically...
Introduction: The Cuatro Ciénegas Basin (CCB) has been isolated since the late Eocene. Most of microorganisms present in CCB have evolved situ and developed genetic metabolic mechanisms to adapt extreme environments. Objectives: To investigate biotechnological potential bacteria from CCB, as well establish phylogenetic relationship among them. Methodology: Bacteria were pure culture samples different waterbodies CCB.Bacteria identified using 16S rDNA gene their was determined maximum...
Abstract Three novel starch derivatives with antibacterial properties are synthesized through a rather simple multistep synthesis route. In first step, sodium periodate oxidation of the hydroxyl groups (C2–C3) yields di‐aldehyde structure, which is used to attach N,N‐dimethylbenzylamine by Schiff base formation. Then, amino aminated quaternized three different ammonium salts (4‐bromobutyl‐pyridinium bromide, 4‐bromobutyl‐benzalkonium and 4‐bromobutyl‐quinolinium bromide). The resulting...
Abstract. Recently, there is growing interest in obtaining bioactive compounds from species the family Cactaceae, which has been little analyzed at genomic and transcriptomic level. We here report assembly of genome Cereus fernambucensis we six cactus genomes (Carnegiea gigantea, Lophocereus schottii, Pachycereus pringlei, Pereskia humboldtii, Selenicereus undatus Stenocereus thurberi), annotation putative genes, modeling three-dimensional structures their predicted proteins involved...
