Correction to: AMB Expr 8:123 (2018) https://doi.org/10.1186/s13568-018–0652-x

Following publication of the original article (Lyu et al. 2018), the authors would like to correct the accession number in the last sentence of the "Metagenomic sequencing" section of the article.

The correct number is SRP149020 instead of SRP179020. This has been corrected with this erratum.
