CO2 incubator ozone sterilization device
PROBLEM TO BE SOLVED: To provide an apparatus that ensures sterilization of a COincubator, has no leakage of fed ozone gas to the outside, uniformly circulates ozone in a storage and constantly and continuously controls an ozone concentration.SOLUTION: The apparatus for ozone sterilization of a COincubator includes: a sterilization tent 1 with an airtight hole 8a for airtightly protruding a leading end part of a tube connection part 14a provided in the COincubator 11 to the outside and a discharge part 9a for discharging ozone gas to the outside, for covering the COincubator 11 airtightly; an ozone gas generator 18 for applying circulating sterilization to the inside and the outside of the COincubator 11 covered by the sterilization tent 1 by pressure-feeding the ozone gas to the tube connection part 14a; and an ozone gas neutralization unit 26 for neutralizing and eliminating the ozone gas discharged from the discharge part 9a.

Enzymatic α/β Inversion of C-3 Hydroxyl of Bile Acids and Study of the Effects of Organic Solvents on Reaction Rates
Enzymatic α/β inversion of the C-3 hydroxyl of numerous bile acids containing different numbers of hydroxyl groups in the skeleton and side chains of different lengths has been carried out.Inversion was obtained in two steps through the sequential use of the commercial enzymes 3α- and 3β-hydroxysteroid dehydrogenase, employed in the free form or immobilized on Eupergit C.The transformations were practically quantitative and the products more than 98percent pure.NAD was regenerated in situ with the pyruvate/lactic dehydrogenase system and NADH with the formate/formate dehydrogenase system.The effects of product inhibition on reaction rates and the favorable effects produced by low concentrations (7-10percent, v/v) of ethyl acetate and ethanol were also examined.

Introducing Δ11 unsaturation into steroid compounds
A process for the introduction of Δ11 unsaturation into steroid compounds having a C-12 sulfonate ester group is described. Dehydrosulfonation is carried out by reacting the sulfonate with a hexaalkylphosphoric triamide. The process is particularly useful with steroid compounds that also contain a blocked C-7 hydroxy group. The process yields the 11-enate in preference to the 6,11-dienate. The yield of the process can be increased by carrying out the reaction in the presence of a weak base.
