Recovery of RNA adsorbed onto sorbents following storage at 4°C.

<p>Data is presented as the ratio of the RNA recovered on a given day to that recovered for the same sorbent on day one of the experiment. Recovery of RNA from NS (black), NS-G (blue) NS-T (green), and NS-B (red) sorbents. An RNA control in water under identical storage conditions was also monitored over this time period (gray).</p

Biofilm community structure and the associated drag penalties of a groomed fouling release ship hull coating

<p>Grooming is a proactive method to keep a ship’s hull free of fouling. This approach uses a frequent and gentle wiping of the hull surface to prevent the recruitment of fouling organisms. A study was designed to compare the community composition and the drag associated with biofilms formed on a groomed and ungroomed fouling release coating. The groomed biofilms were dominated by members of the Gammaproteobacteria and Alphaproteobacteria as well the diatoms <i>Navicula</i>, <i>Gomphonemopsis</i>, <i>Cocconeis</i>, and <i>Amphora.</i> Ungroomed biofilms were characterized by Phyllobacteriaceae, Xenococcaceae, Rhodobacteraceae, and the pennate diatoms <i>Cyclophora</i>, <i>Cocconeis</i>, and <i>Amphora.</i> The drag forces associated with a groomed biofilm (0.75 ± 0.09 N) were significantly less than the ungroomed biofilm (1.09 ± 0.06 N). Knowledge gained from this study has helped the design of additional testing which will improve grooming tool design, minimizing the growth of biofilms and thus lowering the frictional drag forces associated with groomed surfaces.</p

Biocathode MCL Curated Metagenome

This file contains the curated metagenome assembled from a combination of eight biological replicates of Illumina short read sequencing data, two closed genomes and one plasmid sequence derived from PacBio RSII sequencing of DNA isolated from two pure cultures, and one closed genome with a plasmid assembled from PacBio metagenomic data.  The genome bins and unbinned contigs matching the three complete genome sequences and two plasmids were removed from the short read metagenome assembly and replaced by the closed sequences.  Raw data, parent metagenome assembly, and isolate sequences are linked through NCBI Bioproject PRJNA244670 at https://www.ncbi.nlm.nih.gov
