title: Metatranscriptomics of microbial phototropic mat growing at 68 centigrades
design: Microbial mats growing at 66 58 and 48 °C were sampled using a cork borer with a diameter of 7 mm. Cores 1 cm thick were collected in triplicate at noon (12:00 h PM) for DNA and RNA (metagenomic/metatranscriptomic) analyses.
