Biochemical Studies of Amylases in the Silkworm,
-Different amylase enzymes were identified by analysis of digestive fluid and haemolymph in diapausing and nondiapausing strains of silkworm, Bombyx mori. The diapausing strain showed negligible digestive amylase activity at a pH range of 3-11, while the nondiapausing strain registered strikingly higher amylase activity at pH 9.2. Higher levels of undigested starch was found in the faecal matte...
متن کاملStudies on Plant Hypertensinase
Many plants contain an enzyme similar in most biological properties to the hypertensinase obtained from blood and some animal tissues, notably kidney and intestinal mucosa. Wheat bran is a rich source of the plant hypertensinase, and from it a potent, non-toxic preparation was made by the use of isoelectric and ammonium sulfate precipitation as the means of purification. Hypertensinase derived ...
متن کاملStudies on Isolated Plant Protoplasts
Isolated tomato fruit protoplasts have been observed to take up both tobacco mosaic virus and ferritin by the process of pinocytosis. These studies have involved electron microscopic observations on thin sections of suitably fixed and embedded material. These electron microscopic studies have also shown that very close association exists between the nucleus and chloroplasts in these proto plas...
متن کاملA monograph on amylases from Bacillus spp
Owing to the production of alpha, beta and gamma amylase subtypes; starch degrading microbes, especially bacteria have an invincible role in the food, fermentation, textile and paper industries. Of them, α-amylases from Bacillus spp. have contributed tremendous advancements in bio-industry, especially in starch, detergent and pharmaceutical arena. Though general reviews are seen in literature o...
متن کاملClxvii. Studies on Plant Amylases. I. the Effect of Starch Concentration upon the Velocity of Hydrolysis by the Amylase of Germinated Barley
IT is clear that, for the determination of enzymic reaction-velocity under readily definable conditions, the states near the initiation of the reaction are decidedly the best. Usually however this part of the progress has been left unexplored and delineation of it has been based merely upon empirical expressions of doubtful value. In the present paper data have been directly collected within a ...
