متن کاملForty-first Conference Preliminary Studies on the Enzymic "removal" of Dextran from Deteriorated Cane Juice
Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...

From as early as 2700 BC until fairly recently leather was also in the forefront of information technology with its use (as skins, vellum and parchme...
متن کاملRemoval of "tightly bound" nucleotides from phosphorylating submitochondrial particles.
Phosphorylating submitochondrial particles from beef heart (ETPH) prepared here contained about 2.4 nmol of ATP and 1.9 nmol of ADP/mg of protein after repeated washing of the particles. Essentially all of the "tightly bound " ATP and ADP was removed by trypsin treatment. The trypsin-treated ETPH had increased ATPase activity, undiminished NADH oxidase and succinate oxidase activity, but energy...
