Cinnamoyl CoA reductase （CCR） and cinnamyl alcohol dehydrogenase （CAD） catalyze the last steps of mono- lignol biosynthesis. In Arabidopsis, one CCR gene （CCR1, Atlg15950） and two CAD genes （CAD C At3g19450 and CAD D At4g34230） are involved in this pathway. A triple cad c cad d ccrl mutant, named ccc, was obtained. This mutant displays a severe dwarf phenotype and male sterility. The lignin content in ccc mature stems is reduced to 50% of the wild-type level. In addition, stem lignin structure is severely affected, as shown by the dramatic enrichment in resistant inter-unit bonds and incorporation into the polymer of monolignol precursors such as coniferaldehyde, sinapaldehyde, and ferulic acid. Male sterility is due to the lack of lignification in the anther endothecium, which causes the failure of anther de- hiscence and of pollen release. The cc~ hypolignified stems accumulate higher amounts of flavonol glycosides, sinapoyl malate and feruloyl malate, which suggests a redirection of the phenolic pathway. Therefore, the absence of CAD and CCR, key enzymes of the monolignol pathway, has more severe consequences on the phenotype than the individual absence of each of them. Induction of another CCR （CCR2, Atlg80820） and another CAD （CAD1, At4g39330） does not compensate the absence of the main CCR and CAD activities. This lack of CCR and CAD activities not only impacts lignification, but also severely affects the development of the plants. These consequences must be carefully considered when trying to reduce the lignin content of plants in order to facilitate the lignocellulose-to-bioethanol conversion process.

Performance Investigation of Membrane Electrode Assemblies for High Temperature Proton Exchange Membrane Fuel Cell

引用

Journal of Power and Energy Engineering 2013年第5期1卷 95-100页

作者： Huaneng Su Sivakumar Pasupathi Bernard Bladergroen Vladimir Linkov bruno g. pollet HySA Systems Competence Centre South African Institute for Advanced Materials Chemistry University of the Western Cape Private Bag X17 Bellville 7535 South Africa

Different types of ABPBI (poly(2,5-benzimidazole)) membranes and polymer binders were evaluated to investigate the performance of MEAs for high temperature proton exchange membrane fuel cell (HT-PEMFC). The properties of the prepared MEAs were evaluated and analyzed by polarization curve, electrochemistry impedance spectroscopy (EIS), cyclic voltammetry (CV) and durability test. The results showed that MEA with modified ABPBI membrane (AM) has satisfactory performance and durability for fuel cell application. Compare to conventional PBI or Nafion binders, polytetrafluoroethylene (PTFE) and polyvinylidene difluoride (PVDF) are more attractive as binders in the catalyst layer (CL) of gas diffusion electrode (gDE) for HT-PEMFC.
