In this study, a novel method to synthesis of 1,3,5,7-tetraacetyl octahydro-1,3,5,7-tetraazocine or 1,3,5,7-tetraacetyl-1,3,5,7-tetraazacyclooctane (TAT) was used through acetolysis of 3,7-diacetyl-1,3,5,7-tetraazabicyclo-[3.3.1]nonane (DAPT) with acetic anhydride in the presence of sodium acetate as catalyst. Optimized reaction conditions were obtained by changing temperature, time and startin...
At. Most bacteriologists held that the old Voges?SKauer's test (1898) was not a satisfactory test for the differentiation of the coli-serogenes group of organisms. During carbohydrate fermentation by the aerogenes group of bacilli, acetoin (acetylmethyl carbinol) is formed, and this is detected by caustic potash and peptone. Acetoin is oxidized to diacetyl, and this reacts with caustic potash a...
We report the draft genome sequences of four Enterococcus faecium strains isolated from Argentine regional cheeses. These strains were selected based on their technological properties, i.e., their ability to produce aroma compounds (diacetyl, acetoin, and 2,3-butanediol) from citrate. The goal of our study is to provide further genetic evidence for the rational selection of enterococci strains ...
