This study aimed to understand the impact of innovation and trust of the aT (Korea Agro-Fisheries & Food Trade Corporation) agri-food online platform on the activation of service and the switching of service. To gather data for this study, 160 questionnaires were distributed to consumers who had experience purchasing from the aT agricultural food online platform, and 150 of these responses were used for the final analysis. The findings of the study revealed a significant effect of the innovation and trust of the aT agricultural food online platform service on the satisfaction of its users. Furthermore, Hypotheses 2, 6, 7, and 8 were not supported, suggesting that a higher perception of innovation of the aT agricultural online platform may not affect the activation of service and the switching of service, and did not mediate through service satisfaction and cost burden. Based on the stable business foundation for the long-standing agricultural distribution sector in the platform role and function of the Agricultural and Fishery Cyber Exchange, a distribution public corporation in the agricultural sector, it was found that there is a positive and active intention to use the service. The implications of this study are to secure transactions centered on MD (Merchandiser) for matching transactions in the private sector, and to convert the B2B (Posmall) platform service, which has maintained a passive online platform through intermediary transaction activities, from a closed-mall-based business structure to an active open-mall.

Hydrogenotrophicmethanogens can use gaseous substrates like H2 and CO2 in methane production. We successfully have operateda novel hollow-fiber membrane biofilm reactor (Hf-MBfR) for stable methane production from H2 and CO2 undercontinuous operation. H2 and CO2 were diffused into waterthrough the membrane without bubbles formation in theHf-MBfR operated at pH 4.5~5.5 over 70 days. Focusing on the presence of hydrogenotrophic methanogens, we analyzedthestructure of the microbial community in the reactor. Denaturinggradient gel electrophoresis was done with bacterial and archaeal 16S rDNAprimers. Real-time qPCRwas performed to check the variance in the methanogens according to the operation time. Finally, the microbial community at a condition with maximum methane production were analyzed by pyrosequencing methods. The results showed that acidicoperation of a methane production reactor without any pH adjustment inhibitedacetogenic growth and enriched the hydrogenotrophic methanogens, decreasing thegrowth of acetoclastic methanogens.

Anaerobic fermentation of food waste (FW) and waste activated sludge (WAS) for hydrogen production was performed in CSTR (Continuous Stirred tank reactor) under various HRTs and volumetric mixing ratio (V/V) of two substrates, FW and WAS. The specific hydrogen production potential of FW was higher than that of WAS. However, pH drop in the CSTR for hydrogen production from FW was higher than that from WAS. The maintenance of desired pH during fermentative hydrogen production is regarded as the most important operation parameter for the stable hydrogen production. Therefore, when the potential of hydrogen production from FW and better buffer capacity of WAS, the proper mixture of FW and WAS for fermentative hydrogen production were considered as a useful complementary substrate. The maximum yield of specific hydrogen production, 140 mL/g VSS, was found at HRT of 2 day and the volumetric mixing ratio of 20:80 (WAS : FW). The spatial distribution of hydrogen producing bacteria was observed in anaerobic fermentative reactor using fluorescent in situ hybridization (FISH) method.
