Layer-by-layer assembly of a redox enzyme displayed on the surface of elongated bacteria into a hierarchical artificial biofilm based anode.

چکیده
To achieve an efficient electron transfer communication between bacteria and electrodes, several strategies including enzyme surface display, bacteria elongation as well as layer-by-layer assembly techniques were used to assemble bacteria, methylene blue, multiwall carbon nanotubes, and carbon papers into hierarchical micro/nano artificial biofilm based bioanodes.

Preparation of Novel Thin-Film Composite Nanofiltration Membranes for Separation of Amoxicillin
Several novel composite membranes were prepared to separate and recycle amoxicillin from pharmaceutical wastewater via nanofiltration process. The synthesis of these membranes included three stages: 1- preparation of polysulfone ultrafiltration membranes as a support via phase separation process, 2- modification of its surface by interfacial polymerization as a selective layer (polyamide), and ...

One of the most commonly observed surface structures on the prokaryotic cell envelopes is monomolecular crystalline array of proteinaceous subunits termed Surface Layers or S-layers. Due their self assembly ability and the highly ordered, regular structure down to the nanometer scale, S-layers were demonstrated to possess a great potential for nanobiotechnological applications. Some probiotic b...
متن کاملProtein and Lactose Separation by Modified Ultrafiltration Membrane using Layer by Layer Technique
Layer-by-Layer (LbL) is a method which can be used for nanoscale coating and surface functionalization of a material. LbL technique mainly uses the electrostatic attracting between charged materials (polyelectrolytes, nanoparticles, etc.) and an oppositely charged surface. In this study, protein separation (BSA) from lactose solution was carried out using the LbL self-assembly method, which was...

Polyurethane polymer plays an important role in health care, and it is widely used in medical devices and instruments. However, the low biocompatibility and biofilm formation on the surface can be regarded as a challenging issue. Engineering the wetting capability of the surface is an effective way to increase the biodegradability of polymer surfaces with sufficient bulk properties. In this stu...
متن کاملThe Electrosome: A Surface-Displayed Enzymatic Cascade in a Biofuel Cell’s Anode and a High-Density Surface-Displayed Biocathodic Enzyme
The limitation of surface-display systems in biofuel cells to a single redox enzyme is a major drawback of hybrid biofuel cells, resulting in a low copy-number of enzymes per yeast cell and a limitation in displaying enzymatic cascades. Here we present the electrosome, a novel surface-display system based on the specific interaction between the cellulosomal scaffoldin protein and a cascade of r...
