Abstract: Disclosed are a catalyst for oxidative coupling reaction of methane, a method for preparing the same, and a method for oxidative coupling reaction of methane using the same. The catalyst includes a mixed metal oxide, which is a mixed oxide of metals including sodium (Na), tungsten (W), manganese (Mn), barium (Ba) and titanium (Ti). It is possible to obtain paraffins, such as ethane and propane, and olefins, such as ethylene and propylene, with high efficiency through the method for oxidative coupling reaction of methane using the catalyst.

Abstract: Disclosed herein are a calcium salts-supported metal catalyst, a method for preparing the same, and a method for the hydrodeoxygenation reaction of oxygenates using the same. The catalyst, in which a metal catalyst is supported on a carrier of a calcium salt, for example, calcium carbonate, has the effect of increasing the efficiency of hydrodeoxygenation reaction of oxygenates.

Abstract: Disclosed are a heteropolyacid catalyst for producing gamma-valerolactone, which is supported on M-Beta zeolite (M=Sn, Ti, Zr or Hf), and a method for preparing the same and a method for manufacturing gamma-valerolactone using the catalyst. The catalyst has an effect of producing gamma-valerolactone from biomass-derived furfural at a high yield through a one-pot process.

Abstract: The furfural-resistant strain containing the furfural-resistant gene according to the present disclosure may be effectively grown in a furfural-containing medium. Accordingly, the problem that microorganism fermentation was difficult because toxic by-products such as furfural are contained in a hydrolysate derived from inedible lignocellulosic biomass may be solved. Further, according to the method for producing a strain of the present disclosure, the resistant gene may be selected from relatively small number of target genes. Thus, time, cost and the like for developing the resistant strain may be saved. Further, this method for identifying genes may be broadly applied to methods for identifying various unknown functional genes in addition to the furfural-resistant gene.

Abstract translation: 含有根据本公开的糠醛抗性基因的糠醛抗性菌株可以有效地在含糠醛的培养基中生长。 因此，可以解决微生物发酵困难的问题，因为衍生自不可食用的木质纤维素生物质的水解产物中含有糠醛等有毒副产物。 此外，根据本公开的菌株的制造方法，抗性基因可以选自相对少量的靶基因。 因此，可以节省开发耐药菌株的时间，成本等。 此外，用于鉴定基因的方法可广泛地应用于除了糠醛抗性基因之外鉴定各种未知功能基因的方法。
