Metagenomics Analysis of Microorganisms in Freshwater Lakes of the Amazon Basin
نویسندگان
چکیده
The Amazon Basin is the largest hydrographic basin on the planet, and the dynamics of its aquatic microorganisms strongly impact global biogeochemical cycles. However, it remains poorly studied. This metagenome project was performed to obtain a snapshot of prokaryotic microbiota from four important lakes in the Amazon Basin.

Assessing the Diversity and Specificity of Two Freshwater Viral Communities through Metagenomics
Transitions between saline and fresh waters have been shown to be infrequent for microorganisms. Based on host-specific interactions, the presence of specific clades among hosts suggests the existence of freshwater-specific viral clades. Yet, little is known about the composition and diversity of the temperate freshwater viral communities, and even if freshwater lakes and marine waters harbor d...
متن کاملProductivity and salinity structuring of the microplankton revealed by comparative freshwater metagenomics
Little is known about the diversity and structuring of freshwater microbial communities beyond the patterns revealed by tracing their distribution in the landscape with common taxonomic markers such as the ribosomal RNA. To address this gap in knowledge, metagenomes from temperate lakes were compared to selected marine metagenomes. Taxonomic analyses of rRNA genes in these freshwater metagenome...
متن کاملMetagenome Sequencing of Prokaryotic Microbiota Collected from Rivers in the Upper Amazon Basin
Tropical freshwater environments, like rivers, are important reservoirs of microbial life. This study employed metagenomic sequencing to survey prokaryotic microbiota in the Solimões, Purus, and Urucu Rivers of the Amazon Basin in Brazil. We report a rich and diverse microbial community.

River water is a small percentage of the total freshwater on Earth but represents an essential resource for mankind. Microbes in rivers perform essential ecosystem roles including the mineralization of significant quantities of organic matter originating from terrestrial habitats. The Amazon river in particular is famous for its size and importance in the mobilization of both water and carbon o...
متن کاملSurvey of bacteria associated with abdominal flap of freshwater crab (Potamon ebonyicum) at Ebonyi River basin Nigeria
Ebonyi River basin of south east Nigeria is home to the freshwater crab Potamon ebonyicum, which are consumed indiscriminately by inhabitants and tourists. Bulk of the crab meat is obtained by crabbing. A preliminary survey of pathogenic bacteria associated with vulnerable morphological part of the crab species was carried out in the basin. Bacteria were isolated from abdominal flaps of the mal...
