Cover Picture: Biotechnology Journal 10/2016

This regular issue of BTJ includes articles on analytical biotechnology, industrial biotechnology and metabolic engineering. The cover is inspired by the article "Chlorella species as hosts for genetic engineering and expression of heterologous proteins: Progress, challenge and perspective" by Bo Yang, Jin Liu, Yue Jiang and Feng Chen which is describing the heterologous proteins expressed in unicellular Chlorella species combined with the production of fine value‐added bioactives ( http://dx.doi.org/10.1002/biot.201500617 ).
