Electrophoretic transfer as a technique for the detection and identification of plant amylolytic enzymes in polyacrylamide gels.

Plant physiology

Kakefuda G, Duke SH.
PMID: 16663595
Plant Physiol. 1984 May;75(1):278-80. doi: 10.1104/pp.75.1.278.

An electrophoretic transfer technique was developed for the specific identification of isozymes of starch debranching enzyme, alpha-amylase, and beta-amylase. Amylolytic enzymes are separated by native polyacrylamide slab gel electrophoresis and proteins in gels are electrophoretically transferred through starch-containing polyacrylamide...

Applied biochemistry and biotechnology

Krishnan MS, Nghiem NP, Davison BH.
PMID: 15304707
Appl Biochem Biotechnol. 1999;77:359-72. doi: 10.1385/abab:78:1-3:359.

The production of ethanol from industrial dry-milled corn starch was studied in a laboratory-scale fluidized-bed bioreactor using immobilized biocatalysts. Saccharification and fermentation were carried out either simultaneously or separately. Simultaneous saccharification and fermentation (SSF) experiments were performed using small,...
