PRODUCTION AND PURIFICATION OF ALGINIC ACID OLIGOSACCHARIDE

摘要

PURPOSE:To obtain the subject compound from sodium alginate in high efficiency owing to the use of an easily handleable enzyme having high optimum temperature and heat-stability range by using a new alginic acid lyase produced by a microorganism belonging to genus Alteromonas. CONSTITUTION:The objective compound is produced by treating sodium alginate with a new alginic acid lyase produced by a microorganism belonging to genus Alteromonas and having the optimum temperature of the enzymatic activity of 45-55 deg.C. The above microorganism is preferably Alteromonas sp. No.1786 (FERM P-11685).
