No previous reports were available which clearly indicated that protozoa itself or bacteria inside protozoa survive or that the interaction of these two microorganisms have ability to reduce nitrate or not, so we assumed that the protozoa fraction, which consisted of protozoa and the bacteria in the cytosol of protozoa, may have the ability to use nitrate as an electron acceptor and then decreased methane emission.
In original photochemical reactions, as the electron donor, the excited RC pigments transfer the electrons to electron acceptor to realize the charge separation and then leave behind "holes".

In addition to embedding nanoparticles in P3HT film, a promising bulk-heterojunction (BHJ) composite system consisting of P3HT as electron donors and methanofullerene [6,6]-phenyl C61-butyric acid methyl ester (PCBM) as electron acceptors were investigated for electrical bistable memory cells [48, 49], Huang et al.
Accordingly, polymers P1-P2 carrying 1,3,4-oxadiazole as an electron acceptor moiety and 3,4-bis[(4-methy1/3methoxybenzyl)oxy] thiophene and 3,4-bis(dodecyloxy) thiophene as electron donors showed reduced band gap, while the polymer P3 containing 3,4-bis[(4-nitrobenzyl)oxy] thiophene as electron donor displayed slightly increased band gap.
It also provides an opportunity to examine specific photocatalytic reaction parameters such as the effect of electron acceptor concentrations and light intensity at the catalyst surface.
Moreover, the nitrile groups of the NBR are good electron acceptors and therefore can interact more strongly with the electron-donating hydroxyl groups of the CNTs.
