    摘要: A method of determining in a discrete analyzer the total sugars content of a tobacco sample containing sucrose, glucose and fructose, comprises the steps of, converting the sucrose to glucose and fructose, enzymatically converting the glucose and fructose to glucose-6-phosphate in the presence of hexokinase, reacting the glucose-6-phosphate with nicotinamide-adenine dinucleotide in the presence of glucose-6-phosphate dehydrogenase to give reduced nicotinamide-adenine dinucleotide, the amount of reduced nicotinamide-adenine dinucleotide produced being directly proportional to the total sugars content of the sample, measuring the concentration of reduced nicotinamide-adenine dinucleotide in the sample, and generating a signal indicative of the concentration of reduced nicotinamide-adenine dinucleotide and hence of the total sugars content of the sample. Deactivation of enzymes by any cyanogen bromide that may be present is prevented by the addition of dithioerythritol to the reaction mixture.

    摘要: A novel antibiotic complex of "vancomycin-like" antibiotics, AAD 216 complex, is produced by the cultivation of a fermentation broth containing Kibdelosporangium aridum Shearer gen. nov., sp. nov. ATCC 39323 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The AAD 216 complex and its major bioactive components; AAD 216A, AAD 216B, and AAD 216C exhibit antibiotic activity and growth promotant activity.
