Metagenome of Acidic Hot Spring Microbial Planktonic Community: Structural and Functional Insights
Metagenomic analyses were done to obtain a deeper view of the microbial community structure and to gain insight regarding the functional properties present in the planktonic fraction of these Neotropical high Andean acidic hot springs.
High-mountain Andean ecosystems are rich in biodiversity and natural resources (Myers et al. 2000). The South American Andean region is part of what is known as the “Ring of Fire” and has several hot springs that represent unique and undisturbed extreme environments due to their high elevation and exposure to ultraviolet (UV) light. These springs are heated mainly by the underlying magma chamber from volcanic activity; they are oligotrophic and vary in their geochemistry, such as mineral content, temperature, and pH. Thus far, little is known regarding the microbiomes of these high-mountain ecosystems. A hot spring is characterized by discharge of hot water from a vent. There...
