Special Issue Information
Proteins are the building blocks of life. In contrast to the macromolecules of the genetic substances DNA and RNA, proteins reflect the actual status of a cell. The totality of proteins in a tissue or in a microbial community gives us important information about their physiological status. Activated sludge in sewage treatment plants contains a large number of microorganisms which are responsible for the treatment process. The operators can influence the activity of the activated sludge through the process parameters. However, the metabolisms of the bacteria remain a black box. The analysis of the expressed proteins of the system sheds a light on the black box and opens up new possibilities to understand and better regulate the activated sludge system.
Twenty-five years ago, the extracellular polymeric substances were first extracted from the activated sludge and this enabled the description of their properties. This was followed by more specific analyses of enzyme activities and experiments utilising one- and two-dimensional gel electrophoresis and immunoblots. The procedures are complex but only meaningful to a limited extent. To overcome those limitations, modern methods of proteome analysis are well suited.
The proteome analysis of activated sludge is an interdisciplinary task. This method allows scientists to gain knowledge about the behavior of highly stressed communities in activated sludge which can then be used by engineers to enhance plant control. As part of this Special Edition on “Proteins in the Activated Sludge”, we would like to encourage scientists from different disciplines to contribute to the areas of processing, analysis and evaluation, microbiology, and the benefits of the activated sludge proteomes.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biology is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
