Biodiversity of epiphytic macroalgae (Chlorophyta, Ochrophyta, and Rhodophyta) on leaves of Zostera marina in the northwestern Iberian Peninsula
(Consejo Superior de Investigaciones Científicas - CSIC, 2019-02-28)[Abstract] The composition, abundance, and distribution of epiphytic macroalgae living in meadows of Zostera marina L. in the northwestern Iberian Peninsula are here analyzed. We identified 63 species: 40 red algae, 16 ... -
Bioengineering of β-galactosidases for their use in the food industry
(2017)[Abstract] β-galactosidases are enzymes required in a large number of applications by food industry. In this thesis we engineered the β-galactosidases from Aspergillus niger and Kluyveromyces lactis in order to obtain ... -
Biofilter performance and characterization of a biocatalyst degrading alkylbenzene gases
(2009-06)A biofilter treating alkylbenzene vapors was characterized for its optimal running conditions and kinetic parame-ters. Kinetics of the continuous biofilter were compared to batch kinetic data obtained with biofilm samples ... -
Biofiltration of mixtures of gas-phase styrene and acetone with the fungus Sporothrix variecibatus
(Elsevier, 2010-12)The biodegradation performance of a biofilter, inoculated with the fungus Sporothrix variecibatus, to treat gas-phase styrene and acetone mixtures under steady-state and transient conditions was evaluated. Experiments were ... -
Biofiltration of volatile compound mixtures from pulp and paper industries
(2015)[Resumen] Un biorreactor en dos etapas, consistente en un biofiltro percolador (BTF) como primera etapa y un biofiltro (BF) como segunda etapa, se operó bajo estados estacionario y transitorio, para purificar una mezcla ... -
Biofiltration of waste gases containing a mixture of formaldehyde and methanol
(Springer, 2004-04)Several biofilters and biotrickling filters were used for the treatment of a mixture of formaldehyde and methanol; and their efficiencies were compared. Results obtained with three different inert filter bed materials (lava ... -
Biofiltration of waste gases in a reactor with a split-feed
(Wiley-Blackwell, 2003-06)The efficiency of using different feed strategies was evaluated in the case of a gas-phase biofilter packed with an inert carrier material. During a preliminary control-period, the biofilter was first fed with a single ... -
Biofiltration of waste gases with the fungi Exophiala oligosperma and Paecilomyces variotii
(Springer, 2005-06)Two biofilters fed toluene-polluted air were inoculated with new fungal isolates of either Exophiala oligosperma or Paecilomyces variotii, while a third bioreactor was inoculated with a defined consortium composed of both ... -
Biofuels production (ethanol, butanol, hexanol) from renewable sources
(2018)[Abstract] The search for new energy sources or fuels has increased in recent years. Besides, the increasing demand and greater shortage of conventional fuels, creates the need to replace them by renewable energy sources. ... -
Biogeochemical Processes Controlling Oxygen and Carbon Isotopes of Diatom Silica in Late Glacial to Holocene Lacustrine Rhythmites
(Elsevier, 2010-05-19)[Abstract] Biogeochemical cycles and sedimentary records in lakes are related to climate controls on hydrology and catchment processes. Changes in the isotopic composition of the diatom frustules (δ18Odiatom and δ13Cdiatom) ... -
Biogeography and lake morphometry drive diatom and chironomid assemblages’ composition in lacustrine surface sediments of oceanic islands
(Springer, 2014)[Abstract] Subfossil biotic assemblages in lakes’ surface sediments have been used to infer ecological conditions across environmental gradients. Local variables are usually the major drivers of assemblage composition, but ... -

Bioinformatics approach to mRNA markers discovery for detection of circulating tumor cells in patients with gastrointestinal cancer
(Elsevier, 2008)[Abstract] Background: Detection of tumor cells in the blood, or minimal deposits in distant organs as bone marrow, could be important to identify cancer patients at high risk of relapse or disease progression. Quantitative ... -
Bioinspired hybrid model to predict the hydrogen inlet fuel cell flow change of an energy storage system
(MDPI, 2019-11-07)[Abstract]: The present research work deals with prediction of hydrogen consumption of a fuel cell in an energy storage system. Due to the fact that these kind of systems have a very nonlinear behaviour, the use of traditional ... -
