The development of nitrogen-rich biomass- derived carbon catalysts provides an attractive perspective to substitute for Pt-based electrocatalysts for oxygen reduction reaction （ORR）. We here report a facile strategy for synthesis of a nitrogen-doped biocarbon/graphene-like composite electrocatalyst by pyrolyzing a solid-state mixture of coprinus comatus biomass and melamine under nitrogen protection. The graphtic carbon nitride formed by polycondensation of melamine at 600 ℃ acts as a self-sacrificing template to generate the nitrogen-doped graphene-like sheet, which can function as an inserting agent and self-generating support. The composite catalyst exhibits the most promising catalytic activity towards the four-electron ORR with a half-wave potential of around 0.83 V （vs. RHE）, and more excellent stability and tolerance to methanol/ethanol compared to the commercial Pt/C catalyst. It is interestingly found that both a higher content of nitrogen and a larger ratio of graphitic-nitrogen species, which may derive from self-addition of graphene-like support into the catalyst, can effectively improve theelectrocatalytic activity. The planar N group may be the nitrogen functionality that is most responsible for main-taining the ORR activity in alkaline medium. This study can largely encourage the exploration of high-performance carbon-based catalysts from economical and sustainable fungus biomass.

The aim of this study was to evaluate the effect of allyl isothiocyanate(AITC)on the reactive oxygen species(ROS)metabolism and quality of postharvest coprinus comatus(***).Fresh mushrooms were stored at 4℃with AITC at 5,10,and 20μL/L for 18 d,*** was performed every 3 d,and physicochemical parameters and ROS metabolism related enzymes activities were *** with the control,the application of AITC at 10μL/L significantly(P<0.05)decreased xanthine oxidase activity after 9 d of storage,while it significantly(P<0.05)improved the activities of succinic dehydrogenase,glutathione reductase,peroxidase,catalase,and ascorbate peroxidase in the middle and later stages of ***,the Ca^(2+)-ATPase and superoxide dismutase activities in sample treated by 10μL/L were all significantly(P<0.05)higher than those in the ***,the accumulation trends of malondialdehyde and ROS were retarded and membrane integrity was ***,high-concentration AITC(20μL/L)treatment accelerated the ROS generation and increased electrolyte leakage *** AITC treatments significantly(P<0.05)inhibited the respiration rate during the first 9 d of storage and retarded browning of *** during the storage of 18 *** findings suggested that AITC treatment would be a promising method to maintain *** quality,but the concentrations need to be optimized.

Four different media for growing coprinus comatus strain CC16-8 in submerged culture were screened and subjected to orthogonal testing according to L_ 9 （3~ 4 ）. Data revealed the optimum medium composition （adjusted to pH 8.0） to be: sucrose 3%, corn powder 2%, wheat bran 4%, KH_ 2 PO_ 4 0.1% and MgSO_ 4 ·7H_ 2 O 0.05%. Mycelium dry weights using this medium reached 8.63 g/L after submerged culture for 7.5 d.
