Title: Production of l-tagatose
Inventor: IKUMORI TAKESHI
IPC: C12R1/22
Filed: 1992-05-08
Abstract: PURPOSE:To industrially and advantageously obtain a compound industrially unutilized as a rare glucide by bringing a bacterium, belonging to the genus Klebsiella and having the ability to produce L-tagatose from galactitol into contact with an aqueous solution of the galactitol and then collecting the resul tant product. CONSTITUTION:A bacterium, belonging to the genus Klebsiella and having the ability to produce L-tagatose from galactitol (e.g. Klebsiella pneumoniae IFO3317) is inoculated into a culture medium and cultured at 30 deg.C for 2 days by shaking culture and the resultant culture solution is then centrifuged to collect the bacterial cell. The obtained live bacterial cell is subsequently added to a 0.05 M phosphate buffer solution containing galactitol (at pH 7.0), separately poured into shaking flasks and made to react at 30 deg.C for 2 days by shaking. After completing the reaction, the reactional solution is centrifuged to remove the bacterium and zinc sulfide is added to the resultant supernatant. The pH is regulated to 7.6 and the regulated solution is centrifuged to collect the supernatant, which is then passed through an ion exchange resin and desalted to afford the objective L-tagatose which is a rare glucide from the inexpensive sugaralcohol as a raw material.

Abstract: PURPOSE:To realize high-speed operation without increasing power consumption by using an inverter of constant-current characteristics as a sense circuit for an OR array and by letting a driver circuit operate as a feedback loop. CONSTITUTION:As a sense circuit for an OR array composed of transistor TrQ15, an inverter with a load of constant-current characteristics is used to provide the omission of the input resistance of TrQ15, so that the operation of TrQ15 is increased in speed without increasing power consumption. Further, a driver circuit for the OR array, composed mainly of TrQ13, detects the emitter potential of TrQ12 to determine the base potential of TrQ11, and consequently the emitter output potential of TrQ12 can be suppressed to a certain degree even if a power voltage would increase. Additionally, even if TrQ15 should be saturated, its collector potential can be suppressed below a certain value low enough not to cause malfunction.
