Erratum to: Microb Cell Fact (2015) 14:132 DOI 10.1186/s12934-015-0322-5

Unfortunately, the original version of this article [1] contained an error within the abstract. The sentence beginning with “Membrane integrity assayed by propidium iodide” reads “approximately 10 % of the L. paracasei cell membranes were damaged” but should read “approximately 100 % of the L. paracasei cell membranes were damaged”. The abstract has been corrected in the original article.
