Low CyaA expression and anti‐cooperative binding of cAMP to CRP frames the scope of the cognate regulon of Pseudomonas putida
(2021-03)
Although the soil bacterium Pseudomonas putida
KT2440 bears a bona fide adenylate cyclase gene
(cyaA), intracellular concentrations of 30,50-cyclic
adenosine monophosphate (cAMP) are barely detectable.
By using reporter ...
Influence of bitumen and aggregate polarity on interfacial adhesion
(2017)
The quality of the bitumen–aggregate interface formed in an asphalt mixture is dictated by the physicochemical properties of both materials, such as surface polarity. In order to better understand the role of polarity on ...
Removal of both N-nitrosodimethylamine and trihalomethanes precursors in a single treatment using ion exchange resins
(2017-11-01)
Drinking water utilities are relying more than ever on water sources impacted by wastewater effluents. Disinfection/oxidation of these waters during water treatment may lead to the formation of several disinfection ...
1-Nitro-4-(1-propyn-1-yl)benzene
(2019)
The title compound, C9H7NO2, was prepared by alkynylation of 4-iodonitrobenzene with 1,3-dilithiopropyne in the presence of 1 equivalent of CuI and catalytic amounts of Pd(PPh3)2Cl2. The complete molecule is generated ...
Pristine but metal-rich Río Sucio (Dirty River) is dominated by Gallionella and other iron-sulfur oxidizing microbes
(2017-03)
Whether the extreme conditions of acidity and heavy metal pollution of streams and rivers originating in pyritic formations are caused primarily by mining activities or by natural activities of metal-oxidizing microbes ...
Removal of N-nitrosodimethylamine precursors with powdered activated carbon adsorption
(2016-01-01)
The main objective of this study was to examine the roles of powdered activated carbon (PAC) characteristics (i.e., surface chemistry, pore size distribution, and surface area) in the removal of N-nitrosodimethylamine ...
Monomeric Germanium(II) Amides Bearing β-Diketiminato Ligands: Synthesis, Structural Characterization, and Thermal Properties
(2014-09)
Germanium(II) compounds featuring β-diketiminate-type ligands are attractive for applications as nanoparticle precursors, imaging agents, and components of electronic devices. In this work, we report the synthesis of ...
Modified Laccase-Gold Nanoparticles-Tetrathiafulvalene-SPCEs Based Biosensor to Determine W(VI) in Water
(2017)
It was developed an amperometric biosensor to determine tungsten in water, based on the inhibition of
laccase enzyme, by tungsten ions using pyrocathecol as a substrate. The enzyme was immobilized with a proper
mixture ...
Uncovering the Cultivable Microbial Diversity of Costa Rican Beetles and Its Ability to Break Down Plant Cell Wall Components
(2014)
Coleopterans are the most diverse insect order described to date. These organisms have acquired an array of survival mechanisms through their evolution, including highly efficient digestive systems. Therefore, the coleopteran ...
Caracterización bioquímica y espectroscópica de la interacción del aptámero con componentes de la espora de clostridium difficile y la superficie de óxido de grafeno
(2023)
Clostridioides difficile es un patógeno bacteriano formador de endosporas que causa infecciones asociadas al uso de antibióticos, primordialmente en entornos clínicos. Las esporas de C. difficile son altamente resistentes ...
