Microbial diversity of a fluidized-bed bioreactor treating diesel-contaminated groundwater (Vega Baja, Puerto Rico)
(2006)
Culture and culture-independent techniques were used to characterize the microbial
community structure within a fluidized bed reactor (FBR) used to remediate a dieselcontaminated
aquifer. Under normal operating conditions, ...
Microbial characterization of an unmined porphyry deposit at Bosque del Pueblo (Adjuntas, PR)
(2011)
The results from this work demonstrated the relationship between vegetation cover and the diversity of soil bacterial communities from two sites in an abandoned unmined porphyry deposit at Bosque del Pueblo, Adjuntas, PR. ...
Net-plankton diatoms of Puerto Rican water reservoirs as potential bioindicators of trophic status
(2014)
Diatoms are a group of unicellular algae enclosed in a siliceous exoskeleton called the frustule. This ornamented structure allows for taxonomic identification. Diatoms are frequently used as indicators to monitor the ...
Characterization and detection by In situ gene amplification of marine denitrifying bacteria
(2003)
Recent studies suggest that the oceanic nitrogen budget is unbalanced, primarily
due to a high nitrogen removal in contrast to the fixation rate. This imbalance likely
results from denitrification activity in continental ...
Lead bioaccumulation by three tropical plant species
(2006)
Previous studies indicate that fast growing plants with high biomass could be employed for the remediation of lead (Pb) contaminated sites. Phytoextraction of Pb in a contaminated substrate was evaluated. To evaluate a ...
Degradación de biodiesel y diversidad bacteriana en suelos arenosos de una zona industrial (Guayanilla, Puerto Rico)
(2005)
Biodegradation of biodiesel from an industrial impacted sandy soil (Guayanilla Bay,
Puerto Rico) and bacterial diversity was evaluated. Soil samples were amended with
2,500 mg/Kg of biodiesel and incubated during 41 days ...
Sequence diversity and expression of novel bacterial nitrous oxide reductase (Nosz) genes in tropical environments
(2008)
Nitrous oxide (N2O) is produced in different microbial processes including
denitrification, nitrification and dissimilatory nitrate reduction to ammonia (DNRA)
(Kelso et al. 1999). It has been suggested that nitrification ...
Comunidad bacteriana degradadora de gasolina en un bioreactor de lecho fluidizado
(2004)
The bacterial diversity used to bioremediate gasoline contaminated groundwater in a
fluidized bed reactor (FBR) was determined. Isolation and characterization of
bacterial populations from the bioremediation system was ...
Dinámica y distribución de comunidades bacterianas en dos biorreactores de lodos activados en plantas de tratamiento de aguas residuales domésticas
(2009)
Biological wastewater treatment systems are recognized today as the most common biotechnological application in the World. But despite of their widely distributed use, there is a very limited knowledge of their distinctive ...
Biogeography of copper-rich soil microbial communities associated with Gleichenella pectinata and Sticherus bifidus at Bosque del Pueblo (Adjuntas, PR) and Bosque Estatal de Maricao (Sabana Grande, PR)
(2010)
The biogeography of microbial communities in tropical environment is poorly understood. Recent works in soil microbial ecology have focused on cataloging the diversity of soil bacteria, but few of them have documented how ...
