Tanaka A, Hoshino E.
PMID: 16233236
J Biosci Bioeng. 2002;93(5):485-90. doi: 10.1016/s1389-1723(02)80096-2.

The effects of an anionic surfactant, sodium dodecyl sulfate (SDS), on the kinetic behavior in the hydrolysis of amylose with two bacterial alpha-amylases from Bacillus amyloliquefaciens and B. licheniformis were studied. The catalytic rates of both amylases in the...

Baked-bean waste: a potential substrate for producing fungal amylases.

Applied and environmental microbiology

Hang YD, Woodams EE.
PMID: 16345247
Appl Environ Microbiol. 1977 Jun;33(6):1293-4. doi: 10.1128/aem.33.6.1293-1294.1977.

Baked-bean waste was found to be a favorable substrate for amylase production by Aspergillus foetidus NRRL 337. Under optimum conditions, the yields of alpha-amylase (EC 3.2.1.1) and glucoamylase (EC 3.2.1.3) were 47 and 226 U, respectively, per ml of...

BMC Res Notes. 2011 Jul 20;4:242. doi: 10.1186/1756-0500-4-242.

BACKGROUND: Wheat grains accumulate a variety of low molecular weight proteins that are inhibitors of alpha-amylases and proteases and play an important protective role in the grain. These proteins have more balanced amino acid compositions than the major wheat...

beta-Amylase of maize (Zea mays L.) caryopses was studied during development and germination by means of enzymic, electrophoretic, and immunochemical techniques. beta-Amylase activity increased during caryopsis development to a maximum value at the beginning of the water content plateau...

Amylases in developing barley seeds.

Immunochemical protein studies show that nongliadins of the ethanol-soluble fraction (EF) provide the best biochemical information on genome interrelations in cereals. After electrophoresis (pH 3.2) these genome specific proteins are shown to fall within the category of α-prolamines and...

Genes encoding α-amylase inhibitors are located in the short arms of chromosomes 3B, 3D and 6D of wheat (Triticum aestivum L.).
