Rheological behavior from light to heavy oils: construction of master curves
(American Chemical Society, 2016)"In this work, the rheological behavior of heavy and light stabilized (dead) oils is presented. The viscosity measurements were carried out in two different apparatuses to ensure the repetitiveness and accuracy: a Stabinger ... -
Agave bagasse biorefinery: processing and perspectives
(Springer, 2018)"Agave bagasse (AB) is the main solid waste generated by the tequila industry in Mexico, which is an environmental concern due to its considerable volume of production (377,000 Ton in 2016). AB is a lignocellulosic biomass ... -
Habitat suitability models to make conservation decisions based on areas of high species richness and endemism
(Springer, 2018)"Biodiversity positively relates with the provisioning of ecosystem services and preserving areas with elevated diversity of highly-functional species could help to ensure human well-being. Most studies addressed to make ... -
Mathematical modeling of a composting process in a small-scale tubular bioreactor
(Elsevier, 2017)"A mathematical model is presented to describe a composting process occurring in a tubular bioreactor. The mathematical model is based on heat and mass transfer phenomena under the continuum approximation. The bioreactor ... -
Temporal and spatial variation of waterbirds at Sayula Lagoon, Jalisco, Mexico: a five-year winter season study
(Museu de Ciencies Naturals, 2018)"Wetlands in central Mexico are important habitats for assemblages of migratory and resident birds. To study variation in richness and abundance of waterbirds, we conducted monthly observations in 30 permanent plots ... -
Hydrogen metabolic patterns driven by Clostridium-Streptococcus community shifts in a continuous stirred tank reactor
(Springer, 2018)"The hydrogen (H2) production efficiency in dark fermentation systems is strongly dependent on the occurrence of metabolic pathways derived from the selection of microbial species that either consume molecular H2 or ... -
Evaluation of a membrane bioreactor system as post-treatment in waste water treatment for better removal of micropollutants
(Elsevier, 2016)"Organic micropollutants (OMPs) such as pharmaceuticals are persistent pollutants that are only partially degraded in waste water treatment plants (WWTPs). In this study, a membrane bioreactor (MBR) system was used as a ... -
Acorn weight as determinant of germination in red and white oaks: evidences from a common-garden greenhouse experiment
(Springer, 2018)"Key message In Mexican oaks, germination increases with acorn fresh weight across oak species. Within species, these relationships are stronger in red oaks than in white oaks. In both oak groups, fresh weight of acorns ... -
Aberraciones cromáticas en Aves de México: Una revisión y registros recientes en el Estado de San Luis Potosí
(Neotropical Ornitholigical Society, 2018)"La presencia de aberraciones cromáticas en las aves ha llamado la atención de los investigadores desde hace mucho tiempo. En México se ha notado un reciente incremento de artículos publicados referente a este tema. Por ... -
Methanogenic and Sulfate-Reducing Activities in a Hypersaline Microbial Mat and Associated Microbial Diversity
(Springer, 2018)"Methanogenesis and sulfate reduction are important microbial processes in hypersaline environments. However, key aspects determining substrate competition between these microbial processes have not been well documented. ... -
Microbial recovery of metallic nanoparticles from industrial wastes and their environmental applications
(Wiley, 2018)"In recent years, metallic nanoparticles (NPs) have been produced by biological methods using bacteria and have been used with remarkable environmental applications. This paper emphasizes the basic aspects of microbial ... -
Role of indigenous microbiota from heavily contaminated sediments in the bioprecipitation of arsenic
(Elsevier, 2017)"High arsenic concentrations have been detected in alluvial aquifers of arid and semi-arid zones in Mexico. This work describes the potential of microbial arsenate reduction of the indigenous community present in sediments ... -
Enhancing saccharification of Agave tequilana bagasse by oxidative delignification and enzymatic synergism for the production of hydrogen and methane
(Elsevier, 2018)"Agave tequilana bagasse is a suitable lignocellulosic residue for energy production. However, the presence of lignin and the heterogeneous structure of hemicellulose may hinder the availability of polysaccharides. In this ... -
Temporal and longitudinal biofilm matrix analysis of a biofilter treating ethyl acetate during ozonation
(Springer, 2018)"The present paper focuses on the biofilm composition and pattern of biomass in gas biofiltration of ethyl acetate working under continuous addition of ozone (O3). Two biofilters were operated for 230 days, one under ... -
Effects of five Lacandon Maya agroforestry trees on soil nematode trophic group composition
(Springer, 2018)"The Lacandon Maya have managed their lands in Chiapas, Mexico for hundreds of years without long-term soil degradation by applying their traditional swidden agroforestry system. Lacandon land managers plant and care for ... -
Producción de hidrógeno en continuo a partir de hidrolizados enzimáticos de bagazo de agave obtenidos con la enzima nacional Cellulase 50 XL
(2019-08-26)"El bagazo de agave es un residuo lignocelulósico que puede ser utilizado como sustrato para la producción de hidrógeno (H2). Sin embargo, debido a su estructura compleja, es necesario someterlo a un proceso de sacarificación ... -
