A 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 کاملFour-iron (sulfide) ferredoxin from Bacillus polymyxa.
Ferredoxin from Bacillus polymyxa contains (per mole) four non-heme iron residues, four acid-labile sulfide residues, and four cysteine residues. Its molecular weight is approximately 8,800, and it has an oxidation-reduction potential (E(m)) of -390 mv. It is active as an electron carrier in several ferredoxin-linked enzyme systems.
متن کاملCloning and Characterization of the Beta-Amylase Gene from Bacillus polymyxa
The gene for beta-amylase was isolated from BacUlus polymyxa by molecular cloning in B. subtils. B. subtlis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotriose ...
متن کاملAmmonia Assimilation in Bacillus polymyxa
Pathways of ammonia assimilation into glutamic acid and alanine in Bacillus polymyxa were investigated by "N NMR spectroscopy in combination with measurements of the specific activities of glutamate dehydrogenase, glutamine synthetase, glutamate synthase, alanine dehydrogenase, and glutamic-alanine transaminase. Ammonia was found to be assimilated into glutamic acid predominantly by NADPH-depen...
متن کاملThe endospore of Bacillus polymyxa.
The endospore of Bacillus polymyxa was originally described by Meyer (1897) in a study of a bacillus which he designated Astasia asterospora. Meyer's drawings of the spore, showing ridges and the star shaped aspect, were reproduced by Knaysi (1951) over the name Bacillus asterosporus. It has not been generally recognized that this name is synonymous with B. polymyxa (Smith, et al., 1952). So th...
