Retraction Note to: Bacterial conversion of depolymerized Kraft lignin

The Original Article was published on 05 September 2018

Retraction to: Biotechnol Biofuels (2018) 11:240

The authors have retracted this article [1] because due to a mistake in the laboratory, SEC analyses of some of the lignin samples used had already been published as part of another article [2]. The data in the section “Characterization of depolymerized lignin streams” was therefore inaccurately presented as new, and part of the materials and methods section was incorrect. To avoid confusion this article has been retracted and the authors have been given the opportunity to resubmit their corrected data. All authors agree to this retraction.
