  • Patent number: 10294505
    Abstract: Disclosed is an acetyl-CoA-producing microorganism, which is obtained by imparting malate thiokinase and malyl-CoA lyase enzymatic activities to a microorganism having none of the following (a), (b), (c) or (d), without imparting any of (a), (b), (c) or (d), or, even when one or more of (a), (b), (c) or (d) are imparted, not allowing the functions thereof to be exerted: (a) a carbon dioxide fixation cycle having an enzymatic reaction from malonyl-CoA to malonate semialdehyde or 3-hydroxypropionate, (b) a carbon dioxide fixation cycle having an enzymatic reaction from acetyl-CoA and CO2 to pyruvate, (c) a carbon dioxide fixation cycle having an enzymatic reaction from crotonyl-CoA and CO2 to ethylmalonyl-CoA or glutaconyl-CoA or (d) a carbon dioxide fixation cycle having an enzymatic reaction from CO2 to formate.

  • Patent number: 8680355
    Abstract: A novel olefin production process of the invention can be established as an industrial and practical process of producing an olefin with high selectivity by directly reacting a ketone and hydrogen in a single reaction step. In particular, a novel olefin production process is provided in which propylene is obtained with high selectivity by directly reacting acetone and hydrogen. An olefin production process of the invention includes reacting a ketone and hydrogen at a reaction temperature in the range of 50 to 300° C. in the presence of a Cu-containing hydrogenation catalyst and a solid acid substance.

  • Publication number: 20100076137
    Abstract: Disclosed is a flame-retardant polyamide composition excellent in fluidity during molding and granulation ability on a twin-screw extruder or the like. A molded article produced from the composition is excellent in mechanical properties including stiffness, heat resistance and flame retardancy during a reflow soldering process, and shows low warpage. Specifically disclosed is a flame-retardant polyamide composition comprising 20 to 80 mass % of a specific polyamide resin (A), 1 to 40 mass % of a flame retardant (B), 5 to 60 mass % of a glass fiber (C), and 0.5 to 5 mass % of an auxiliary flame retardant (D), which can be molded in an article having reduced warpage. Preferably, the glass fiber (C) has a cross section having an aspect ratio of greater than 3.
