Studying the Impact of Wall Shear Stress on the Development and Performance of Electrochemically Active Biofilms.

A laminar flow reactor was designed that provides constant and reproducible growth conditions for the bioelectrochemical observation of electroactive bacteria (EAB). Experiments were performed using four reactors in parallel to enable the comparison of EAB growth behavior and bioelectrochemical performance under different hydrodynamic conditions while simultaneously keeping biological conditions identical. With regard to the moderate flow conditions found in wastewater treatment applications, the wall shear stress was adjusted to a range between 0.

Optimal Geometric Parameters for 3D Electrodes in Bioelectrochemical Systems: A Systematic Approach.

In this study, the performance of electroactive bacteria (EAB), cultivated inside tubular electrode ducts, is systematically investigated to derive predictions on the behavior of EAB under conditions limited by electrochemical losses. A modeling approach is applied to assess the influence of the electrochemical losses on the electrochemical performance and scaling characteristics of complex 3D structures, such as sponges and foams. A modular flow reactor is designed that provides laminar and reproducible flow conditions as a platform for the systematic electrochemical and bioelectrochemical characterization of 3D electrodes in bioelectrochemical systems (BES).

-Glycoproteomic Characterization of Mannosidase and Xylosyltransferase Mutant Strains of .

At present, only little is known about the enzymatic machinery required for -glycosylation in , leading to the formation of -glycans harboring Xyl and methylated Man. This machinery possesses new enzymatic features, as -glycans are independent of β1,2--acetylglucosaminyltransferase I. Here we have performed comparative -glycoproteomic analyses of insertional mutants of mannosidase 1A (IM ) and xylosyltransferase 1A (IM ).
