Influence of diligent disintegration on anaerobic …
Objectives: To enhance the performance of microbial fuel cells (MFC) by increasing the surface area of cathode and diligent mechanical disintegration of anaerobic biomass. Results: Tannery effluent and anaerobic biomass were used. The increase in surface area of the cathode resulted in 78% COD removal, with the potential, current density, power density and coulombic efficiency of 675 mV, 147 ...

While the Casparian strip functions to block extracellular diffusion of substances (e.g., microbial patterns) into the stele, a second cell wall modification—endodermal suberin lamellae—eventually surrounds the entire endodermis and is thought to inhibit uptake of molecules into the endodermis, because the hydrophobic suberin layer does not allow molecules from the cell wall to reach the ...
Microbial Cell - an overview | ScienceDirect Topics
Microbial cells and other insoluble materials are normally separated from the harvested broth by filtration or centrifugation. Because of the small size of many microbial cells, it will be necessary to consider the use of filter aids to improve filtration rates, while heat and flocculation treatments are employed as techniques for increasing the sedimentation rates in centrifugation.

Microbial fuel cell - Wikipedia
A microbial fuel cell (MFC) is a bio-electrochemical system that drives an electric current by using bacteria and a high-energy oxidant such as O 2, mimicking bacterial interactions found in nature.MFCs can be grouped into two general categories: mediated and unmediated. The first MFCs, demonstrated in the early 20 th century, used a mediator: a stone that transfers electrons from the ...

17-6-2020 · Identification of enolase in S. thermophilus CGMCC7.179. To characterize whether the enolase from S. thermophilus could bind to microbial surface, an enolase encoding gene enoM was identified in the genome of S. thermophilus CGMCC7.179. It was 1305 bp in size and composed of 435 amino acid residues. Multiple-sequence alignment results showed that the deduced EnoM protein …
