Title: Biological production of organic acid
Inventor: YAMADA HIDEAKI
IPC: C12R1/01
Filed: 1990-02-28
Abstract: PURPOSE:To readily enable a high activity by culturing a microorganism belonging to Rhodococcus genus in the presence of a lactam compound and acting the resultant nitrilase enzyme on a nitrile compound. CONSTITUTION:To a medium containing glucose, peptone, etc., a lactam compound selected from gamma-butylolactam, delta-valerolactam and epsilon-caprolactam is added in an amount of 0.05-2.0W/V% and Rhodococcus rhodochrous (ATCC 33278) strain, etc., is inoculated thereinto. The above-mentioned strain is then aerobically cultured at pH6-10 and 15-37 deg.C for 1-7 days to obtain a nitrilase- active cell (A). The component (A) is added to 0.1-10W/V% substrate solution (B) prepared by dissolving a nitrile compound such as acrylonitrile in a phosphate buffer solution and a reaction is carried out at pH4-10 and 5-50 deg.C for 1min-48hrs to obtain a reaction product (C). The component (C) is subsequently extracted, thus obtaining the objective organic acid (e.g. acrylic acid) corresponding to the nitrile compound.

Title: Zeolite collector
Inventor: HIRAGA TETSUO
IPC: F24J2/04
Filed: 1981-03-31
Abstract: PURPOSE:To eliminate the exposure of a heat collector by burying a heat collector of the titled collector having a heat collector containing zeolite, a condenser and an evaporator in the heat absorption portion of a road surface or the like. CONSTITUTION:When an environmental temperature is lowered as at night, zeolite in a heat collector 1 absorbs steam from the environment due to temperature drop, and the steam pressure is lowered in the system in this manner. Accordingly, water is vaporized from an evaporator 4, and the water in the evaporator 4 is cooled by the vaporization. This cooled water is used as a cooling source. On the other hand, when a road 5 is heated by the solar heat, the colletor 1 is heated by the heat, the zeolite 2 absorbs the heat at that time and  is thus heated to exhaust steam. Said steam is condensed by a condenser 3, and  the water in the condenser 3 is heated at this time. The heated water is used as  a heat source.
