Diversity of the Cabo Rojo solar salterns utilizing culture-dependent methods and description of two novel species
(2017)
Archaea compose the third domain of life and are most notable for the ability of some to thrive in extreme environments, such environment is that of high salinity. This project focused on the culturable haloarchaeal diversity ...
Partial purification of agarases from halophilic microorganisms isolated from marine and hypersaline environments in Puerto Rico
(2017)
Las agarasas son enzimas que son capaces de catalizar la hidrólisis de agar. Se clasifican en dos grupos, que son α-agarasa y β-agarasa, de acuerdo con el patrón de escisión. Varias agarasas se han aislado de diferentes ...
Detection of integron-encoded integrases in environments with moderate anthropogenic impact from Puerto Rico
(2012)
Integrons are genetic elements with a site-specific recombination system which includes an integrase (IntI) capable of capturing and expressing promoterless, circular DNA molecules known as gene cassettes. Although integrons ...
Diversity of moderately halophilic bacteria associated with the soil of the black mangrove, Avicennia germinans
(2011)
Mangroves are complex ecosystems that contribute the coast environment by maintaining
terrestrial and marine food chains, among others. Black mangrove, Avicennia germinans, on
which this study is centered, predominates ...
Phylogenetic and taxonomical characterization of microbial populations putatively capable of autotrophic ammonia oxidation from marine, saline and hypersaline environments at the Cabo Rojo Salterns, Puerto Rico
(2016)
Autotrophic ammonia oxidation has been studied over the years and several enzymes involved in this metabolism have been identified. This metabolism has been detected in several environments, but there are no reports of it ...
Microbial diversity of halotolerant and halophilic endophytes from the mangrove Avicennia germinans located at the solar salterns of Cabo Rojo, Puerto Rico
(2018-12-02)
The relationship between plants and their environment has been described as a continuum, in which changes of a variable may have an effect on another. Ecological shifts in temperature, humidity, and soil chemistry can alter ...
Physiological and transcriptome-based profile of glycosyl hydrolases from the Halophilic archaeon Halogeometricum borinquense
(2017)
Since the discovery of the Archaea domain, a lot of interest has been given to study regulation of gene expression in these microorganisms. However, few reports are available that provides knowledge about how essential ...
Initial approaches towards the understanding of catabolite repression in halophilic Archaea and the characterization of an alpha-glucosidase (maltase) from Haloquadratum walsbyi
(2010)
The work of Carl Woese based on ribosomal RNA sequence analysis from organisms have led scientist to classify life as we know it into three domains. One such domain is the Archaea. There is a lot of interest in studying ...
Analysis of the metabolic and microbial diversity of the solar salterns in Cabo Rojo using metagenomics
(2018-05)
The Cabo Rojo solar salterns is a hypersaline environment located in a tropical climate.
Conditions in these environments remain stable throughout the year and therefore allow for
the establishment of steady microbial ...
Consequences of invasive grass removal on above and below ground ecosystem dynamics within abandoned agricultural land in the Laguna Cartagena National Wildlife Refuge, Puerto Rico
(2014)
In the tropics, abandoned pasturelands often remain in an arrested state of succession due to non-native grass invasions. Initial restoration approaches often focus on the direct removal of these species. To test if invasive ...
