The present invention refers to a process for the electrolytic deposition of a zinc or zinc alloy coating on a metallic substrate, a zinc coated metallic substrate having a specific gloss as well as an aqueous alkaline plating bath for the electrolytic deposition of a zinc or zinc alloy coating on a metallic substrate and the use of a zinc plating bath additive in a process for the electrolytic deposition of a zinc or zinc alloy coating on a metallic substrate and for improving the optical appearance and/or the adhesion of a zinc or zinc alloy coating on a metallic substrate.

Additive for alkaline zinc plating

The aim is to increase the protein product yield in microbial fermentation. This is achieved by a method which introduces into a microorganism not only a first expression construct which encodes the protein, but also a second expression construct which encodes an auxiliary protease which differs from the protein, is proteolytically active and which comprises an amino acid sequence which is at least 50% identical to the amino acid sequence indicated in SEQ ID NO. 1.

Expression method

The invention is abouthost cells which are capable to convert glycerol to serinol. Furthermore, a process for producing serinol is disclosed, which comprises culturinghost cells inactive for triosephosphate isomerase and active for dihydroxyacetone phosphate aminotransferase to convert glycerol to serinol, induction of conversion from glycerol to serinol by adding at least glycerol to the cell culture, and isolating serinol from the cell culture.
