Las celdas de combustible biológicas son dispositivos bio-electroquímicos, donde generalmente el ánodo (pero a veces el cátodo, o ambos) contiene microorganismos capaces de generar y mantener un gradiente electroquí...

Foi realizado um estudo da flora perifítica de diatomáceas (Bacillariophyceae) existente no Rio Jaú, tributário do Rio Negro, Amazônia (2º57'S e 61º49'W). As coletas foram realizadas manualmente nas cheias de 1995...

El alga invasora Undaria pinnatifida (Phaeophyceae, Laminariales) fue reportada por primera vez en Golfo Nuevo en 1992, dispersándose ampliamente a lo largo de 170 km de costa en el norte de la Patagonia, Argentina. Obs...

Abstract The aim of this study was to identify the optimal and superior type of natural calcium for replacing phosphate in cooked ground pork products. To achieve this, 0.5% eggshell calcium (ESC), oyster shell calcium (...

ABSTRACT Nitrogen and phosphorus are essential elements for the growth and performance of organisms, and the environmental N:P ratio can determine the biomass and structure of algal communities. We investigated the effec...

Evidence of teratogenesis and mutagenesis documented in the palynological assemblages of the Middle Triassic Quebrada de los Fósiles Formation, San Rafael Depocenter (Mendoza, Argentina) provide an independent testimony...

The conversion of solar radiation to chemical energy in plants and green algae takes place in the thylakoid membrane. This amphiphilic environment hosts a complex arrangement of light-harvesting pigment-protein complexes...

Abstract Studying microbial biodiversity offers enormous potential for improving the valorisation of plant biomass, particularly in conversion processes. Microorganisms, such as bacteria, fungi, yeasts and algae, play an...

One way that pathogens develop resistance to pharmaceuticals is by forming biofilms, which are 3-D communities of bacteria. As a result, there is considerable interest in identifying new antibiofilm agents from nature th...

In lake food webs, pelagic basal organisms such as bacteria and phytoplankton incorporate mercury (Hg2+) from the dissolved phase and pass the adsorbed and internalized Hg to higher trophic levels. This experimental inve...

Abstract Inclusive education seeks to provide equitable learning opportunities to students with diverse needs. While the “plant kingdom” is a foundational concept in biology, studies show that students—including th...

Nitric oxide synthase (NOS) synthesizes NO from the substrate L-arginine (Arg). NOS with distinct biochemical properties were characterized from two photosynthetic microorganisms, the unicellular algae Ostreococcus tauri...

The aim of this work was to study the oxidative stress effects and histological alterations caused by dietary copper on the filter-feeding freshwater mussel Diplodon chilensis. Bivalves were fed during 6 weeks with the g...

Los aerosoles de origen biológico (bioaerosoles), son una parte importante del complejo de partículas suspendidas en el aire. Los propágulos como: granos de polen, esporas de hongos, algas, quistes de dinoflagelados, ...

Short-time-scale limnological investigations during low-discharge conditions are appropriate for elucidating trophic relationships within the plankton. The grazing pressure of the zooplankters, dominated by r-strategists...

"The presence of sulfated polysaccharides in cell walls of seaweeds is considered to be a consequence of the physiological adaptation to the high salinity of the marine environment. Recently, it was found that sulfated p...

Relatively the specific high salinity ground water in Nineveh province were physically improved with freezing and melting treatment. Also, the algal treatment with Chara vulgaris as a biological treatment were applied, t...

Phosphoenolpyruvate carboxykinase (PEPCK) catalyses the reversible reaction of decarboxylation and phosphorylation of oxaloacetate (OAA) to generate phosphoenolpyruvate (PEP) and CO2 playing mainly a gluconeogenic role i...

Abstract Obesity, as defined by the World Health Organization (WHO), is excessive fat accumulation that can pose health risks and is a disorder of the energy homeostasis system. In typical westernized diets, ω-6 polyuns...

El extracto etanólico crudo (70%) y las fracciones diclorometánica, de acetato de etilo y butanólica de las hojas de A. brasiliana fueron analizados en relación a su actividad antimicrobiana. Las concentraciones inhi...

Numerosos registros bibliográficos se refieren a la utilización de algas en tratamientos para combatir la obesidad. En particular, están muy difundidos los productos comerciales que contienen algas pardas (Phaeophyta)...

Los organismos zoospóricos heterotróficos conforman un grupo heterogéneo perteneciente a los reinos Fungi y Straminipila y se hallan caracterizados por la presencia de talo cenocítico y esporas móviles (zoosporas). ...

"El negocio del startup Algae Liquor consiste en la producción y venta de aceite vegetal como materia prima para la elaboración de biodiesel, conjuntamente con proteína vegetal como suplemento alimenticio para el merc...

The Antarctic rocky coasts are mainly colonized by extensive seaweed communities, which play key roles as food resource, habitat, and refuge for many benthic and pelagic organisms. Due to climate warming, Antarctic marin...
