Bacterial diversity and community structure of two maize varieties (white and yellow) during fermentation/steeping for ogi production, and the influence of spontaneous fermentation on mycotoxin reduction in the gruel were studied. A total of 142 bacterial isolates obtained at 24-96 h intervals were preliminarily identified by conventional microbiological methods while 60 selected isolates were ...

Breeding of yellow-seeded rapeseed (Brassica napus) is preferred over black-seeded rapeseed for the desirable properties of the former. This study evaluated the metabolites and nutritive values of black-seeded rapeseed meal and yellow-seeded meal from the progeny of a B. napus-Sinapis alba hybrid. Yellow-seed meal presented higher protein (35.46% vs. 30.29%), higher sucrose (7.85% vs. 7.29%), l...

The correlation between the yellow colour of the skin and serum bilirubin concentration, reserve albumin concentration, and pH was investigated in 76 icteric neonates. Significant linear correlation existed between yellow colour of the skin and serum bilirubin concentration, reciprocal of the reserve albumin concentration, and the squared hydrogen ion concentration. Furthermore, the basic yello...

Throughour screening programofbioactive secondary metabolites of microbial origin, we have isolated a new azaphilone-type metabolite, diazaphilonic acid (Fig. 1). In this paper, we report the taxonomy of the producing strain, production, isolation, physico-chemical properties and biological activities of diazaphilonic acid. The mycological characteristics of the producing fungal strain PF1195 (...

The efficiency of HZSM-5 Zeolite, tungestophosphoric acid (H3PW12O40) and tungestosililic acid (H4O40SiW12) were investigated in three-component, one-pot synthesis of coumarin dyes. These green and noncorrosive acids were highly efficient in synthesis of some coumarin dyes in excellent yield during concurrent formation of coumarin and benzimidazole or benzoxazole heterocycles (e.g. C. I. disper...

The interaction of small molecules with non-covalent assemblies is of wide interest. The use of a magnetically active reporter nucleus allows information to be obtained in the presence of spectral overlap or in cases of high dynamic range. In this paper, we explore the interaction of a larger probe molecule, 6-fluoro-2-naphthoic acid with assemblies of sunset yellow using (19)F chemical shifts ...

In the course of a study of antiphage substances a yellow, crystalline antibiotic substance, which has been named Chrysomycin, was isolated from an unidentified Streptomyces. A number of yellow antibiotic substances derived from Streptomyces have recently been described, among others aureolic acid (Philip and Schenck, 1953), chartreusin (Leach et al., 1953), limocrocin (Brockmann and Grothe, 19...
