Factors influencing MFC performance are charge transfer resistance (Rct), oxidation rate of fuel, electrode spacing, inoculated organism, solution conductivity, biocompatibility with substrate, pH of cell, electrochemical stability, retention time, loading rate, anodic material and cathodic electron acceptor
[10-12] Several strategies have been adopted to overcome these problems.
However, the quantum yield of electron transport from QA~ to the intersystem of electron acceptors
(cpEo - quantum yield for electron transport -ET) decreased as a function of duration of flooding, especially after the seventh day of flooding.
Among them, oligomers and polymers possessing a three-coordinate boron atom as a strong electron acceptor
have attracted considerable attention owing to their optical and electronic properties [7-9].
Fluorescence changes during the fast part (between steps O and P) of the transient can be primarily correlated with the events taking place in the course of successive reduction of the electron acceptors
of the entire photosynthetic electron transport chain.
Dissimilatory reduction of Fe(III) and other electron acceptors
by a thermus isolate," Applied and Environmental Microbiology, vol.
The process of respiration uses oxygen as a terminal electron acceptor
, passing electrons along a chain and capturing energy released in the form of adenosine triphosphate (ATP).
The useful complementary redox materials were electron acceptors
and include such compounds as, for example, phenyl-hydroquinone, fluorenones, fluorenes, carbazoles that are poly-nitro substituted, and benzene compounds substituted with electron withdrawing groups .
Certain co-metabolic transformations are carried out by fermentative and other anaerobic organisms, in which terminal electron acceptors
are not required.
By using highly electronegative oxygen as a terminal electron acceptor
in the process of oxidative phosphorylation (oxidative metabolism), far more energy is released that can be used for ATE production than is obtained from metabolic processes that use other electron acceptors
, such as occurs in fermentation reactions.
Hence, both polymers and electron acceptors
are in contact with each electrode, generating bi-continuous pathways to each electrode, eliminating pathways that lead nowhere .
I was specifically referring to the extracellular electron transfer of cellular reducing power (electrons) to solid metal oxides, such as iron or manganese oxides, and the conceptual difficulty that was imagined with truly insoluble substrates as electron acceptors
Among the doping materials are electron acceptors
such as iodine and antimony pentachloride.
The decrease in fluorescence level observed afterwards reflects mostly the progressive reopening of the reaction centers as electrons are transferred from the PQ pool to oxidized electron acceptors
located downhill, as discussed above.
These electron carriers are able to generate anodic current in the presence of terminal electron acceptors
(under anaerobic conditions) which is the exceptional example (Kim et al.
Thus far, there has been no discussion about how oxidation is coupled to electron acceptors
so that the energy is captured in an orderly manner, or about [H.
