Quantitative proteomic analysis of Pseudomonas pseudoalcaligenes CECT5344 in response to industrial cyanide-contain ing wastewaters using Liquid Chromatography- Mass Spectrometry/Mass Spectrometry (LC- MS/MS)
(PLOS, 2017)Biological treatments to degrade cyanide are a powerful technology for cyanide removal from industrial wastewaters. It has been previously demonstrated that the alkaliphilic bacterium Pseudomonas ps ... -
Quick and Sensitive Enantioselective Determination of Permethrin in Fruits and Vegetables by Combining Supramolecular Solvents and Chiral Liquid Chromatography-Tandem Mass Spectrometry
(ACS, 2020)Permethrin (PM) is one of the chiral insecticides most widely used around the world. The significant differential toxicity of its four enantiomers and its important adverse effects on human health highlights the need for ... -
Quick supramolecular solvent-based microextraction for quantification of low curcuminoid content in food
(Springer-Nature, 2013)There is a need to monitor the consumption of curcuminoids, an EU-permitted natural colour in food, to ensure that acceptable daily intakes are not exceeded, especially by young children. This paper describes a sensitive ... -
Recent Advances in Extraction and Stirring Integrated Techniques
(MDPI, 2017)The extraction yield of a microextraction technique depends on thermodynamic and kinetics factors. Both of these factors have been the focus of intensive research in the last few years. The extraction yield can be increased ... -
Recycling Oxacillin Residues from Environmental Waste into Graphene Quantum Dots
(MDPI, 2019)Of great concern are the residual antibiotics from dirt that can be found in farm soil and wastewater. This kind of emerging pollutant into engineered nanomaterials is riveting. This work proposes the elimination and ... -
Relationship between Volatile Organic Compounds and Microorganisms Isolated from Raw Sheep Milk Cheeses Determined by Sanger Sequencing and GC–IMS
(MDPI, 2023)Recently, the interest of consumers regarding artisan cheeses worldwide has increased. The ability of different autochthonous and characterized lactic acid bacteria (LAB) to produce aromas and the identification of the ... -
La responsabilidad social de la ciencia y tecnología
(Real Sociedad de Química, 2012)El impacto mutuo de la Ciencia y Tecnología (CyT) y la sociedad/medio ambiente es el tema tratado genéricamente en este artículo. Se considerará la definición de la Responsabilidad Social de la Ciencia y Tecnología tomando ... -
Responsabilidad social: una ruta para alcanzar la excelencia en laboratorios de ensayos y calibraciones
(2013-07-12)Se propone un modelo de gestión estratégico para incluir la gestión de la Responsabilidad Social (RS) como una herramienta que permita no sólo la responsabilidad por la calidad de los resultados y el compromiso con los ... -
Restricted access supramolecular solvents for the simultaneous extraction and cleanup of ochratoxin A in spices subjected to EU regulation
(Elsevier, 2018)A simple and high-throughput sample treatment, based on the use of a supramolecular solvent with restricted access properties (SUPRAS-RAM), was developed for the quantification of ochratoxin A (OTA) in spices subjected ... -
