Cover illustration: Biotech Methods and Advances. This issue of Biotechnology Journal covers methods for systems metabolic engineering as well as downstream processing. The cover image shows an artist's impression of a magnetic fusion protein consisting of antibody like particles (pale blue) and ferritin subunits (pale green) encapsulating an iron core (red). These “Magnetizable antibody-like proteins” are described by Dehal et al. pp. 596–605 (http://dx.doi.org/10.1002/biot.200900273). Art by Mark Bradshaw, Pixelweave 3D.

Schematic representation of a microfluidic side‐entry reactor with reactants of a penicillin G acylase reaction and pH sensors integrated along the reaction channel. The pH sensors enabled real‐time monitoring of the reaction progress in a microfluidic reactor. Alkaline buffers added to the reactor's side‐entries balanced the pH and increased product yield, thereby highlighting the feasibility of pH control. The cover is prepared by Pia Gruber, Marco P.C. Marques, Philipp Sulzer, Roland Wohlgemuth, Torsten Mayr, Frank Baganz and Nicolas Szita authors of the article ”Real‐time pH monitoring of industrially relevant enzymatic reactions in a microfluidic side‐entry reactor (μSER) shows potential for pH control“ ( https://doi.org/10.1002/biot.201600475 ).

This regular issue of BTJ includes articles on biocatalysis, biochemical engineering, and bioprocess engineering. This cover page highlights the applications of biomolecules (e.g., proteins, enzymes, and DNA) in ionic liquids (ILs). The technological utility of biomolecules can be enhanced significantly by combining them with ILs. Image is provided by Magaret Sivapragasam, Muhammad Moniruzzaman, and Masahiro Goto authors of ”Recent advances in exploiting ionic liquids for biomolecules: Solubility, stability and applications“ ( http://dx.doi.org/10.1002/biot.201500603 ).

Cover illustration Focus: Transgenic Crops. This issue of BTJ highlights two articles about transgenic crops. Erlendsson et al. show for the first time that barley can be used as a green factory for growth factors (pp. 163–171); Herman et al. use a transclinic medicine model to access the safety of transgenic crops (pp. 172–182); Image © PhotoDisc/Getty Images. http://dx.doi.org/10.1002/biot.200900111 ; http://dx.doi.org/10.1002/biot.200900217 .

This regular issue of BTJ features articles on the production of biofuels, stem cells and gene expression. The cover is inspired by the article ”Cooperation of Aspergillus nidulans enzymes increases plant polysaccharide saccharification“ by Robson Tramontina et al. which analyzed a mixture of several Aspergillus enzymes involved in the degradation of polysaccharide. © Dr_Kateryna – Fotolia.com
