Recycling Rhizopus oryzae resting cells as biocatalyst to prepare near eutectic palmitic-stearic acid mixtures from non-edible fat
(Elsevier, 2016)Here we studied non-edible fat waste as a starting material to prepare eutectic mixtures of biomaterials. Initially, the fat was hydrolyzed using water and R. oryzae resting cells. The hydrolysis was performed in organic ... -
Reduction of conjugated dienoic carboxylic acids and esters with sodium dithionite
(Chemical Society of Japan, 1982)Reduction of 2,4-alkadienoic acids and esters with sodium dithionite was carried out in aqueous solution or under PTC conditions to give, almost exclusively, Z:E isomeric mixtures of the corresponding 3-alkenoic acids and ... -
Refrigerated storage and calcium dips of ripe 'Celeste' sweet cherryfruit: combined effects on cell wall metabolism
(Elsevier, 2017)Ripening-related firmness loss shortens considerably the storage potential of sweet cherry (Prunus avium L.), thus limiting postharvest handling, transportation, and commercialisation. The biochemical mechanisms underlying ... -
Regeneration of volatile compounds in Fuji apples following ultra low oxygen atmosphere storage and its effect on sensory acceptability
(American Chemical Society, 2008)The aim of this work was to assess whether extra time spent under AIR conditions after storage in an ultra low oxygen (ULO) atmosphere could allow the regeneration of volatile compound emission without negatively affecting ... -
Relationships between volatile production, fruit quality, and sensory evaluation in granny smith apples stored in different controlled-atmosphere treatments by means of multivariate analysis
(American Chemical Society, 1999)Aroma compounds, quality parameters, and sensory evaluation of Granny Smith apples were analyzed after 3, 5, and 7 months of cold storage in three controlled-atmosphere (CA) treatments, in which oxygen and carbon dioxide ... -
Reliability of the density functional approximation to describe the charge transfer and electrostatic complexes involved in the modeling of organic conducting polymers
(American Physical Society, 2005)Both the intermolecular interaction energies and the geometries for M ̄ thiophene, M ̄ pyrrole, M n+ ̄ thiophene, and M n+ ̄ pyrrole ͑with M = Li, Na, K, Ca, and Mg; and M n+ = Li+ , Na+ , K+ , Ca2+, and Mg2+͒ have been ... -
Removal of inorganic mercury from aqueous solutions by biomass of the marine macroalga Cystoseira Baccata
(Elsevier, 2005)The ability of Cystoseira baccata algal biomass to remove Hg(II) from aqueous solutions is investigated. The mercury biosorption process is studied through batch experiments at 25ºC with regard to the influence of contact ... -
Rendered-protein hydrolysates as a low-cost nitrogen source for the fungal biotransformation of 5-hydroxymethylfurfural

Repeated applications of CPPU on highbush blueberry cv. Duke increase yield and enhance fruit quality at harvest and during postharvest
(Instituto de Investigaciones Agropecuarias (INIA), Ministerio de Agricultura, Chile, 2014)Applications of N-(2-chloro-4-pyridyl)-N'-phenylurea (CPPU) can increase blueberry (Vaccinium corymbosum L.) yield and fruit size, but their impact on postharvest is unknown. We studied repeated CPPU applications effects ... -
Resequencing the Vrs1 gene in Spanish barley landraces revealed reversion of six-rowed to two-rowed spike
(Springer Science+Business Media B.V., part of Springer Nature, 2018-04-12)Six-rowed spike 1 (Vrs1) is a gene of major importance for barley breeding and germplasm management as it is the main gene determining spike row-type (2-rowed vs. 6-rowed). This is a widely used DUS trait, and has been ... -
Rice-Associated Rhizobacteria as a Source of Secondary Metabolites against Burkholderia glumae
(MDPI, 2020-05-31)Various diseases, including bacterial panicle blight (BPB) and sheath rot, threaten rice production. It has been established that Burkholderia glumae (B. glumae) is the causative agent of the above mentioned pathologies. ... -
Ripening-related cell wall modifications in olive (Olea europaea L.) fruit: A survey of nine genotypes
(Elsevier, 2020-08-04)The production of olive (Olea europaea L.) is very important economically in many areas of the world, and particularly in countries around the Mediterranean basin. Ripening-associated modifications in cell wall composition ... -
Role of charge regulation and fluctuations in the conformational and mechanical properties of weak flexible polyelectrolytes
(MDPI, 2019-11-29)This work addresses the role of charge regulation (CR) and the associated fluctuations in the conformational and mechanical properties of weak polyelectrolytes. Due to CR, changes in the pH-value modifies the average ... -
Seasonal variations in proton binding characteristics of dissolved organic matter isolated from the southwest baltic sea
(ACS publications, 2021)The physicochemical characteristics of dissolved organic matter (DOM) strongly influence its interactions with inorganic species such as protons and trace elements in natural waters. We collected water samples at Boknis ... -
Selection footprints in barley breeding lines detected by combining genotyping-by-sequencing with reference genome information
