DOCUMENT TYPE: Patent CA Section: 3 (Biochemical Genetics) Vectors are constructed for cloning and expression of genes in yeast. The vectors contain resistance to one or more of the following cytotoxins: a-ketoaldehydes, heavy metals, 8-hydroxyquinolines, tetramethylthiuramdisulfides, iodoactamides, and N-ethylmaleimides. Thus, Sau3AI fragments of chromosomal DNA isolated from Saccharomyces cerevisiae DKD-5D-H conferring resistance to glyoxal (G), methylglyoxal (MG), ethylglyoxal (EG), and phenylglyoxal (PhG) were ligated to BamHI treated plasmid YEp-13 to give recombinant plasmids pYG10, pYMG14, pYEG2, and pYPhG20 conferring Mg, EG, and PhG resistance, resp. .

Studies on microorganisms in fermented soybean foods: Studies on microorganisms in fermented soybean foods. IV. Flavorous substances in miso. 1. Volatile polycarbonyl compounds in miso. Honma, N.; Ishihara, K. (Niigata Women's Coll., Ebigase, Japan). Hakko Kogaku Kaishi, 55(1), 36-43 (Japanese) 1977. CODEN: HKOKDE. DOCUMENT TYPE: Journal CA Section: 17 (Foods) Volatile polycarbonyl compds. present in miso (fermented soybean paste) were converted to 2,4-dinitrophenylhydrazones and were identified by comparison with authentic compds. of their Rf values and colors on thin-layer chromatog., detectability on gas-chromatog., and UV, visible, and IR spectra. Glyoxal [107-22-2], 2-oxopropanal [78-98-8], 2-oxobutanal [4417-81-6], diacetyl [431-03-8], and 2,3-pentanedione [600-14-6] were identified, and 2,3-hexanedione and 2,3-heptanedione were tentatively identified. At least 2 dicarbonyl compds. were detected but not fully identified. Diacetyl was the main polycarbonyl compd., followed by 2-oxopropanal and 2,3-pentanedione. 600-14-6 and 4417-81-6 which are cas registry numbers of substances are two of reagents here. Of all carbonyl compds. in miso >90% were aliph. monocarbonyl compds. and 4-8% were polycarbonyl compds. .
