Virulencia de hongos nativos del orden Hypocreales sobre Bemisia tabaci, estudio de las condiciones óptimas para el desarrollo de los hongos y registros de moscas blancas silvestres para Costa Rica
(2020)
Los hongos Hypocreales son hongos entomopatógenos con potencial en control biológico de insectos plaga. El objetivo de este estudio fue identificar especies de hongos patógenos que parasitan insectos de la familia Aleyrodidae ...
Quantitative Physiology Approaches to Understand and Optimize Reducing Power Availability in Environmental Bacteria
(2015-06-04)
The understanding of how carbon fluxes are distributed through a metabolic network offers an overview of the pathways that a given microorganism uses to produce energy, reducing power, and biomass. These invaluable data ...
Aposematismo en la rana Phyllobates vittatus (anura: Dendrobatidae): integrando defensas, señales y riesgo de depredación
(2019-10-01)
El aposematismo es una estrategia defensiva en la cual animales que poseen una defensa lo advierten a los depredadores a través de una señal conspicua. Por ejemplo, algunos animales tóxicos o con poca palatabilidad le ...
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)
The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ...

Compounds of formula (I) or formula (II), compositions and methods useful for treating and/or preventing a fungal infections are provided. wherein the substituents are as defined in the appended claims.
Redox stress reshapes carbon fluxes of Pseudomonas putida for cytosolic glucose oxidation and NADPH generation
(2020)
The soil bacterium and metabolic engineering platform Pseudomonas putida tolerates high levels of endogenous and exogenous oxidative stress, yet the ultimate reason of such property remains unknown. To shed light on this ...
Streptomyces sp. M54: an actinobacteria associated with a neotropical social wasp with high potential for antibiotic production
(2021-01-17)
Abstract Streptomyces symbionts in insects have shown to be a valuable source of new antibiotics. Here,
we report the genome sequence and the potential for antibiotic production of ‘‘Streptomyces sp. M54’’, an Actinobacteria ...
