Purification and Characterization of an Exo-1,5-α-L-Arabinanase from Aspergillus sojae
amylopectin cluster rice starch branching enzyme starch debranching enzyme starch synthase
2008/4/20
An exo-1,5-α-L-arabinanase was purified as an electrophoretically homogenous protein from a liquid culture of Aspergillus sojae. The molecular mass of the purified enzyme was estimated to be 41 kDa by...
A Note on the Metabolic System for the Synthesis of the Tandem-Cluster Structure of Amylopectin in Rice Endosperm
amylopectin cluster rice starch branching enzyme starch debranching enzyme starch synthase
2008/4/20
The tandem-cluster structure of amylopectin must be a refined product that higher plants have evolved from the cluster-free random branched structure of glycogen. During the evolutionary process, plan...
Accumulation of Cello-oligosaccharides during Bacterial Cellulose Production by Acetobacter xylinum
Acetobacter xylinum cello-oligosaccharides cellulose acetan
2008/4/20
Acetobacter xylinum ATCC23769 produces not only cellulose but also various oligosaccharides during cell growth. These oligosaccharides accumulated and increased gradually up to about half the amount o...
Adsorption of Cationic Methylene Blue and Anionic Methyl Orange by Crude Drug Starches

2008/4/20
In order to use effectively the starch from the extracted residue of crude drugs, adsorption characteristics of cationic methylene blue (MB) and anionic methyl orange (MO) were investigated. Starches ...
Amylase Activities and Values in Hot and Cold Water Extracts of Pearl Millet
amylase pearl millet malting water extracts
2008/4/20
Amylase activities from various cultivars of pearl millet and a sorghum cultivar and their values in cold water and hot water extracts were studied. The α-amylase and β-amylase activities and values i...
An Improved Method for the Quantitative Analysis of Commercial Isomaltooligosaccharide Products Using the Calibration Curve of Standard Reagents
isomaltooligosaccharide isomaltooligosaccharide product quantitative analysis isomaltotriosylglucose
2008/4/20
An improved method for the quantitative analysis of isomaltooligosaccharide (IMO) products by HPLC with a polymer-based amino column was developed. The column was much higher in durability than a sili...
An Oxidation Stable and Chelator-resistant, Calcium-free α-Amylase from the Alkaliphilic Bacillus Isolate KSM-K38
calcium-free α-amylase Bacillus oxidative stability chelator resistance
2008/4/20
We found a novel α-amylase (AmyK38) in a culture of a novel, alkaliphilic Bacillus sp. strain KSM-K38. The enzyme was an alkaline, liquefying α-amylase, having a pH optimum of 8.0-9.5, and exhibiting ...
Analysis of Amylose Chain Lengths Forming Complexes with Lysophosphatidylcholines
