Author Correction: Microbial community dynamics and coexistence in a sulfide-driven phototrophic bloom

The Original Article was published on 17 January 2020

Correction : Environmental Microbiome (2020) 15:3

The original article briefly discusses Microviridae viruses found in the metagenomes in the Abstract (Results), Results (Metagenome derived insights into Chlorobiales populations), Discussion (New species of green sulfur bacteria and possible viral predation), and Conclusions. Since the article’s publication it has come to light that the sequences associated with the Microviridae viruses belong to PhiX 174 (Genbank Accession Number NC_001422), a member of Microviridae family. These sequences were a contamination originating from the use of PhiX DNA as a control in Illumina sequencing platforms [1]. Hence, the authors would like to issue a correction to strike out any results and discussions associated with Microviridae virus(es). After removing PhiX 174-associated sequences from the metagenomic data, the most abundant viral sequences were affiliated with Myoviridae, a viral family which includes phages that are suspected to affect Chlorobi [2]. Figure S20 in Additional file 1 has been updated to reflect this change. This change does not affect any other results presented in the original article. The sequence data associated with this work was deposited in the NCBI SRA as raw sequence data and remains unaffected.
