Degradation of naproxen and carbamazepine in spiked sludge by slurry and solid-phase Trametes versicolor systems
(2010-04)
rowth and activity of the white-rot fungus Trametes versicolor on sewage sludge were assessed in bio slurry and solid-phase systems. Bioslurry cultures with different loads of sludge (10%, 25% and 38%, w/v)
were performed. ...
Evaluation of growth in diesel fuel and surfactants production ability by bacteria isolated from fuels in Costa Rica
Evaluación de crecimiento en combustible diesel y capacidad de producción de surfactantes en bacterias aisladas de combustibles en Costa Rica
(2012)
A total of 149 bacterial strains previously isolated from fuels stored in Costa Rica were selected in terms of their ability to grow aerobically in diesel and produce bioemulsifier active compounds. The diesel growth was ...
Butanol production by Clostridium beijerinckii BA101 using cassava flour as fermentation substrate: enzymatic versus chemical pretreatments
(2011)
Cassava flour (CF), a cost-effective source of
starch, was employed as a substrate for successful acetone butanol-ethanol (ABE) production by batch-fermentation
with Clostridium beijerinckii. The effect of temperature,
initial ...
Presencia de los genes de toxigenicidad nheA, nheBy nheC en cepas de Bacillus cereus aisladas de leches deshidratadas en Costa Rica
Detection of toxigenic genes nheA, nheB and nheC in Bacillus cereus strains isolated from powdered milk samples in Costa Rica
(2014)
La leche en polvo es un producto de alto consumo humano que no precisa de ser conservado en frío, no obstante, diversos microorganismos pueden deteriorarlo. En la población costarricense, también se observa este alto ...
Grupo Bacteroides fragilis en heces humanas no diarreicas y su sensibilidad antimicrobiana
Bacteroides fragilis group in non-diarrheic human feces and its antimicrobial susceptibility
(2006-12)
Bacteroides es el género de bacterias anaerobias predominante en el colon humano, y sus diez especies son la causa de la mayoría de las
infecciones anaerobias. Ya que casi todas las infecciones que causan son endógenas, ...
Zoonotic species of the genus arcobacter in poultry from different regions of Costa Rica
(2015)
In recent years, emerging pathogens have received special attention due to their consequences for public health. Given that
Arcobacter has been isolated in Costa Rica from commercial meat poultry samples, the aim of this ...
Hydrocarbon Degrading Microflora in a Tropical fuel-Contaminated Aquifer: Assessing the Feasibility of PAH Bioremediation
(2012-01)
An aquifer located within a petroleum processing plant in Moín, Costa Rica, suffers hydrocarbon
pollution. This study aimed to determine the ability of indigenous microorganisms from this site to degrade
polycyclic ...
Nickel Biosorption by Acinetobacter Baumannii and Pseudomonas Aeruginosa Isolated from Industrial Wastewater
Bioadsorção de niquel por Acinetobacter baumannii e Pseudomonas aeruginosa isoladas de águas residuais industriais
(2006-12)
Nickel biosorption ability was evaluated in two bacterial strains: Acinetobacter baumannii UCR-2971 and
Pseudomonas aeruginosa UCR-2957, resulting in greatest adsorption at pH 4.5 and a residence time of 100
minutes. ...
Arcobacter: Comparison of Isolation Methods, Diversity, and Potential Pathogenic Factors in Commercially Retailed Chicken Breast Meat from Costa Rica
(2014)
Arcobacter species have been recognized as potential food- and waterborne pathogens. The lack of standardized isolation methods and the relatively scarce knowledge about their prevalence and distribution as emerging pathogens ...
Accelerated biodegradation of selected nematicides in tropical crop soils from Costa Rica
(2014)
Degradation and mineralization behavior of select ed nematicides was studied in soil samples from fields culti vated with banana, potato, and coffee. Degradation assays in
most of the studied soils revealed shorter ...
