C1 gas biorefinergy using bioelectrochemical system for value-added chemicals
김중래 한국공업화학회 2018 한국공업화학회 연구논문 초록집 Vol.2018 No.0
The carbon monoxide conversion into volatile fatty acids and valueadded platform chemicals, have been of great interest in industrial biotechnology due to the demand syngas fermentation and treatment of industrial flue gas. Nevertheless, the biological CO conversion process is difficult to be implemented into the industry due to lack of costeffective process. Although many technical advancements in process and biocatalysts have been developed and implemented, the low conversion yield and/or cell growth of CO-utilizing microbes still hinders to develop appropriate biorefinery process for gas substrate. Recently, bioelectrochemical system based CO/CO<sub>2</sub> conversion provide a potential route to improve conversion efficiency and cell growth of strains. In this presentation, we summary the research outcome of BES based CO/CO<sub>2</sub> conversion as well as recent reports and application in respect of the development of gas conversion bioprocess system.

Sustainable energy and carbon neutrality has been a key issue in waste/wastewater management. Recovery and recycling of materials such as nutrients and metal are highly anticipated to achieve a zero-energy treatment and pollution control, and subsequently secure sustainability of exhausted resources. The difficulty of resource recovery from waste/wastewater and sediment is mainly due to the immature technology, and dispersed (or less concentrated) target resources in wastewater and natural source that results in technical challenges and poor economics. Bioelectrochemical system (BES) has been widely investigated for electrical energy recovery, intermediate chemical production and recently for useful resource recovery. Certain amounts of energy in wastewater can be used as reducing power for energy production as well as for useful material recovery from wastewater and natural sources using a novel inter-disciplinary biotechnology, BES simultaneously treating wastewater.

The present paper gives a brief sketch of the algal flora and vegetation at Eocheong Do which is located far away 39mi1es from Gun san, facing the Yellow sea. The current running round the coast of Eocheong Do is the tributary of the warm current known as "kuroshio", but in winter the current becomes weak, and the island is under the influence of the colder water of sea shore. The intertidal and sublittoral collections of marine algae were made at 8 points in june, 1976 April, 1977 and May, 1978(Fig. 1) In the list(Table. 1)78 species are inumerated, including 13 species of Chlorophytae, 22 species of Phaeophytae, and 43 species of Rhodophytae. Segawa's c/p was estimated about 0. 6. From the point of view to c/p, this area has a frigid marine flora. It is interesting that Ptilota pectinata(Grun) Kjellmanf, litoralis Kjellman was found in tide pools of the lower intertidal belt, what had been present only along the southern coast of our country. The writer collected fortunately 20 species, whick have never been recorded as it had been found in this area.
