Title: Production of alkyl or alkenyl aryl sulfoxide
Inventor: OOTA HIROMICHI
IPC: C12P11/00
Filed: 1984-04-02
Abstract: PURPOSE:To improve the reaction yield of sulfoxide, suppressing the production of sulfone produced as a by-product of the oxidation reaction of sulfoxide, by adding a long-chain unsaturated carboxylic acid as a carbon source to an inorganic salt medium in the proliferation of bacteria. CONSTITUTION:A sulfide is oxidized by using a rapidly proliferable bacterial strain, and using an inorganic salt medium containing a long-chain unsaturated carboxylic acid as a carbon source. The substrate concentration can be made to be relatively high, and the reaction yield can be improved remarkably. The medium is an inorganic salt medium containing 1-5vol% long-chain unsaturated carboxylic acid such as oleic acid, linoleic acid, etc. as a carbon source. The medium has excellent property to suppress the by-production of sulfone in contrast with an inorganic salt medium containing a 14-20C alpha-olefin or saturated hydrocarbon as a carbon source. The cultivation is carried out preferably under aerobic condition, e.g. by shaking cultivation, at 20-40 deg.C, and the pH of the medium is especially preferably 7-8.

Filed: 1983-04-15
Abstract: PURPOSE:To obtain the ratio of two analog signals only by use of one A/D converter and also to obtain the digital value of the ratio by using a dividing circuit which consists of the A/D converter and a counting circuit. CONSTITUTION:The oscillation output of a variable frequency oscillator 12 is applied to an up/down counter 13 together with the output of a polarity deciding circuit 16 to count the oscillation output according to the output of the circuit 16, and the counted value is led to a D/A converter 11 and an ROM17. The counter 13 holds the current counted value VD when an analog output VX converted on the basis of a voltage VB applied to a reference voltage terminal ref becomes equal to the output VA of a linearization correcting circuit 30. In this case, VD=VX/VB, so VD=VA/VB because VX=VA, thereby obtaining the ratio VA/VB. On the other hand, a correspondence table containing digital signals showing ratios and color temperatures is stored in the ROM17, so a signal is used for address assignment to output the corresponding color temperature, which is indicated on an indicator 20.
