Influence of natural organic matter and pH on phosphate removal by and filterable lanthanum release from lanthanum-modified bentonite
Water Research, 202, 117399.
Contributors: Y. Zhi n, n , K. Grieger n , O. Duckworth n , J. Jones n & D. Knappe n
author keywords: Eutrophication; Lake restoration; Lanthanum release; Humic and fulvic acid; Phosphate management

MeSH headings : Bioelectric Energy Sources / microbiology; Electrochemical Techniques; Electrodes
TL;DR:
It is suggested that additional bioelectrochemical investigations of both pure and mixed cultures, over a wide range of potentials, are needed to better understand how to set and evaluate optimal anode potentials for improving BES performance.

Direct Biological Conversion of Electrical Current into Methane by Electromethanogenesis
Environmental Science & Technology, 43(10), 3953–3958.
MeSH headings : Bioelectric Energy Sources / microbiology; Biofilms; Carbon Dioxide / metabolism; Electricity; Electrochemical Techniques; Electrodes; Electrons; Methane / metabolism; Methanobacterium / cytology; Methanobacterium / physiology; Methanobacterium / ultrastructure
TL;DR:
Results show that electromethanogenesis can be used to convert electrical current produced from renewable energy sources (such as wind, solar, or biomass) into a biofuel (methane) as well as serving as a method for the capture of carbon dioxide.

High Surface Area Stainless Steel Brushes as Cathodes in Microbial Electrolysis Cells
Environmental Science & Technology, 43(6), 2179–2183.
MeSH headings : Bacteria / metabolism; Bioelectric Energy Sources; Electrodes; Electrolysis / instrumentation; Electrolysis / methods; Hydrogen / metabolism; Platinum; Stainless Steel
TL;DR:
High surface area stainless steel brush cathodes produce hydrogen at rates and efficiencies similar to those achieved with platinum-catalyzed carbon cloth cathodes in single-chamber MECs without the need for expensive cathodes.

Hydrogen Production by Geobacter Species and a Mixed Consortium in a Microbial Electrolysis Cell
Applied and Environmental Microbiology, 75(24), 7579–7587.
MeSH headings : Bacteria / metabolism; Bioelectric Energy Sources; Electrolysis; Geobacter / metabolism; Hydrogen / metabolism
TL;DR:
It is demonstrated that Geobacter species are capable of obtaining similar hydrogen production rates and energy recoveries as mixed cultures in an MEC and that high coulombic efficiencies in mixed culture MECs can be attributed in part to the recycling of hydrogen into current.

Tubular Membrane Cathodes for Scalable Power Generation in Microbial Fuel Cells
Environmental Science & Technology, 41(9), 3347–3353.
MeSH headings : Bioelectric Energy Sources; Carbon / chemistry; Catalysis; Cobalt / chemistry; Electricity; Electrodes; Polyesters / chemistry; Polymers / chemistry; Porphyrins / chemistry; Sulfones / chemistry
TL;DR:
The results demonstrate that an MFC design using tubular cathodes coated with nonprecious metal catalysts, and brush anodes, is a promising architecture that is intrinsically scalable for creating larger systems.
