  • Base-catalyzed dehydration of substituted cis-1,2-dihydroxycyclohexa-3,5-dienes
    Patent number: 5093514
    Abstract: A process for dehydrating compounds of the formula ##STR1## where --R is --CH.dbd.CH.sub.2, --C.tbd.CH --C.tbd.N or ##STR2## in an aqueous solution thereof is disclosed. In the case where R is --CH.dbd.CH.sub.2 or --C.dbd.CH, the temperature is preferably at least 50.degree. C. and preferably 75.degree. to 100.degree. C. The base is at least 0.1N and preferably 1.0 to 8N. Preferred bases are NaOH, KOH and C.sub.5 OH. In the case where --R is C.tbd.N, the temperature preferably is 20.degree. to 50.degree. C.

  • L-ascorbic acid production in microorganisms
    Patent number: 5001059
    Abstract: Improved production of ascorbic acid is obtained empolying Chlorella as a microorganism source and growing the culture under a controlled pattern of carbon source supply. Greatly improved ratios of ascorbic acid to total carbon supplied as well as enhanced ascorbic acid concentrations in the fermentor are obtained.C. pyrenoidosa UV101-158 was deposited at the A.T.C.C. on June 27, 1985 and given Accession No. 53170.
