(2012-12-18)Esta invención se refiere a extractos fenólicos conteniendo procianidinas, propelargonidinas y flavanolignanos, con propiedades/actividades potencialmente beneficiosas para la salud humana, y obtenidos a partir de las ... -
Transformation of humic substances by the freshwater Ascomycete Cladosporium sp.
(2017)The ecological relevance of fungi in freshwater ecosystems is becoming increasingly evident, particularly in processing the extensive amounts of polymeric organic carbon such as cellulose, chitin, and humic substances (HS). ... -
A New Parasitic Chytrid, Staurastromyces oculus (Rhizophydiales, Staurastromycetaceae fam. nov.), Infecting the Freshwater Desmid Staurastrum sp.
(2017-08)Chytrids are a diverse group of ubiquitous true zoosporic fungi. The recent molecular discovery of a large diversity of undescribed chytrids has raised awareness on their important, but so far understudied ecological role ... -
Microplastics alter composition of fungal communities in aquatic ecosystems
(2017)Despite increasing concerns about microplastic (MP) pollution in aquatic ecosystems, there is insufficient knowledge on how MP affect fungal communities. In this study, we explored the diversity and community composition ... -
Microplastic pollution increases gene exchange in aquatic ecosystems
(2018-06)Pollution by microplastics in aquatic ecosystems is accumulating at an unprecedented scale, emerging as a new surface for biofilm formation and gene exchange. In this study, we determined the permissiveness of aquatic ... -
Aquatic fungi: targeting the forgotten in microbial ecology
(2016-06)Fungi constitute important and conspicuous components of aquatic microbial communities, but their diversity and functional roles remain poorly characterized. New methods and conceptual frameworks are required to accurately ... -
A preliminary report of aquatic hyphomycetes isolated from Anzali lagoon (Gilan province, North of Iran)
(2019)Aquatic hyphomycetes equipped with a rich array of extracellular enzymes are involved in bioremediation of anthropogenic pollutants, plastics, aromatic contaminants and petroleum hydrocarbons. The current study contributes ... -
Pilze in aquatischen Ökosystemen
(2020-06)Pilze sind phylogenetisch und funktionell vielfältige, allgegenwärtige Bestandteile fast aller Ökosysteme der Erde, einschließlich aquatischer Ökosysteme, die sich von hochmontanen Seen bis in den tiefen Ozean erstrecken. ... -
Diversity and hidden host specificity of chytrids infecting colonial volvocacean algae
(2018-05)Chytrids are zoosporic fungi that play an important, but yet understudied, ecological role in aquatic ecosystems. Many chytrid species have been morphologically described as parasites on phytoplankton. However, the majority ... -
Fungi in aquatic ecosystems
(2019-03)Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ... -
Highly diverse fungal communities in carbon-rich aquifers of two contrasting lakes in Northeast Germany
(2019-10)Fungi are an important component of microbial communities and are well known for their ability to decompose refractory, highly polymeric organic matter. In soils and aquatic systems, fungi play an important role in carbon ... -
Taxonomical and functional diversity of Saprolegniales in Anzali lagoon, Iran
(2020)Studies on the diversity, distribution and ecological role of Saprolegniales (Oomycota) in freshwater ecosystems are currently receiving attention due to a greater understanding of their role in carbon cycling in various ... -
Resistencia a desinfectantes y su relación con la resistencia a los antibióticos
(2020)Objetivo: sistematizar los principales mecanismos de acción de los desinfectantes y describir mecanismos de resistencia comunes entre biocidas y antibióticos. Métodos: se realizó una revisión bibliográfica de artículos ... -
Microplastic ingestion by a herring Opisthonema sp. in the Pacific coast of Costa Rica
(2020-07)Current knowledge of the presence of microplastics (MP) in marine species in tropical areas is still limited. The presence of MP was examined in the gastrointestinal content of 30 filter feeders of the herring Opisthonema ... -
Estudio de aditivos anticorrosivos para las aleaciones comerciales de la batería alcalina alumino-aire
(2020)La sociedad actual está avanzando hacia un modelo energético más responsable y sostenible. La punta de lanza de esta necesaria tendencia es el uso de fuentes de energía renovables y la reducción de las emisiones de CO2 ... -
Optical component
(2010-02-15)El invento trata de un componente óptico, que comprende un primer reflector esférico y un segundo reflector esférico, el cual está colocado para reflejar un rayo de luz varias veces entre el primer reflector y el segundo ... -
Aparato y método para evaluar microfiltración en materiales
(2017-03-01)La presente invención se relaciona al campo de la investigación o análisis de materiales por medio de la determinación de sus características físicas o químicas, más específicamente con la determinación de la permeabilidad ... -
Clustering binary data by application of combinatorial optimization heuristics
(2019-08-09)We study clustering methods for binary data, first defining aggregation criteria that measure the compactness of clusters. Five new and original methods are introduced, using neighborhoods and population behavior combinatorial ...
