Metagenomic libraries data sets from the hypersaline benthic microbial mats of the Fraternidad Lagoon, Puerto Rico, using an indirect DNA extraction method

Microbial mats are biofilm formations that reflect early Earth ecosystems. To investigate their microbial diversity, an indirect DNA extraction method was applied to benthic ephemeral microbial mats from Fraternidad Saltern Lagoon during rainy and dry seasons. This approach yields high molecular DNA, suitable for metabolic and diversity analysis.
