Preliminary assessment of small scale bacterial depuration of Crassostrea gigas and Anadara spp., Gulf of Nicoya, Costa Rica
(Universidad Nacional (Costa Rica), 2013-12)
Bivalve molluscs are sold without any sanitary control in Costa Rica, which represents a public health risk due to the possible accumulation of pathogenic bacteria. Small scale bacterial depuration treatments were preliminarily ...
Effect of metal concentration on growth and luminescence of luminous bacteria straims isolated from golfo de Nicoya, Costa Rica
(Universidad Nacional (Costa Rica), 2021-01)
Luminescence in bacteria is catalyzed by luciferase. When these microorganisms are exposed to toxic substances, the bioluminescent enzyme system can be inhibited. The objective of this study was to analyze the potential ...
Evaluación poblacional y pautas de ordenamiento pesquero del complejo Opisthonema (Pisces: Clupedae), Golfo de Nicoya, Costa Rica
(Universidad Nacional (Costa Rica), 2010)
En Costa Rica, el complejo Opisthonema es uno de los componentes más importantes de la captura pesquera y sustenta una de las flotas semiindustriales del Golfo de Nicoya. Con base en esta importancia económica, el objetivo ...
Avances biotecnológicos sobre maricultura en Costa Rica. Una revisión de la investigación desarrollada por la Escuela de Ciencias Biológicas de la Universidad Nacional
(Universidad Nacional (Costa Rica), 2017-07-31)
El desarrollo de la maricultura en Costa Rica ha requerido de la validación, la innovación y la generación de conocimiento científico biotecnológico. Se presenta una revisión de los principales ...
Shifts in bacterioplankton community structure between dry and wet seasons in a tropical estuary strongly affected by riverine discharge
(Elsevier (Países Bajos), 2023-12)
Estuaries are among the most productive ecosystems in the world and are highly dynamic due to the interaction
of freshwater and seawater, which results in strong spatial gradients in physico-chemical conditions. ...
Characterization of culturable marine luminescent bacteria isolated from the Gulf of Nicoya, Costa Rica
(Consejo Superior de Investigaciones Científicas (España), 2017)
Luminescence in bacteria is dependent on quorum sensing and is regulated by the luxCDAB operon. The expression of this operon genes can be inhibited by explosion to toxic substances such as heavy metals.
The ratio between ...
Bacterias luminiscentes: Alternativa para la evaluación de la contaminación marino costera en Costa Rica
(Colegio de Biólogos (Costa Rica), 2014-07-12)
Se lograron aislar bacterias luminiscentes del Golfo de Nicoya,
Costa Rica. Se discuten las aplicaciones actuales de estos
microorganismos como bioindicadores de contaminación ambiental
y su potencial como alternativa ...
Evaluation of Escherichia coli concentrations in Crassostrea gigas and seawater in two oyster growing areas in the Gulf of Nicoya, Costa Rica
(Universidad Nacional (Costa Rica), 2014-12)
Costa Rica does not have references on the health quality of Crassostrea gigas growing areas, which can pose a po tential public health risk. This study evaluated the temporal trends of Escherichia coli concentrations in ...
Phytotelm to assess bacterial multi-resistance to the antibiotics in a deep tropical forest
(Research Square Company (Estados Unidos), 2022-02-22)
Paradoxically, the use of antibiotics has resulted in the proliferation of resistant microorganisms in
environments where they were not thought to be likely to appear. In this context, this research aimed to
evaluate the ...
Bacterial multi-resistance to antibiotics in water from plant cavities (phytotelms) in a deep tropical forest from Costa Rica
(Universidad Estatal a Distancia (UNED) (Costa Rica), 2023)
Introduction: The spread of antimicrobial resistance in natural environments continues to be reported throughout the world; nevertheless, there is no study about phytotelms (water in the natural cavities of plants) in the ...
