biostudies-literatureUnknown10Cheng H<h4>Background</h4>L-arabinose is an important intermediate for anti-virus drug synthesis and has also been used in food additives for diets-controlling in recent years. Commercial production of L-arabinose is a complex progress consisting of acid hydrolysis of gum arabic, followed by multiple procedures of purification, thus making high production cost. Therefore, there is a biotechnological and commercial interest in the development of new cost-effective and high-performance methods for obtaining high purity grade L-arabinose.<h4>Results</h4>An alternative, economical method for purifying L-arabinose from xylose mother liquor was developed in this study. After screening 306 yeast strains, a strain of Pichia anomala Y161 was selected as it could effectively metabolize other sugars but notMicrobial cell factories43https://www.ebi.ac.uk/biostudies/studies/S-EPMC3125199biostudies-literatureA novel method to prepare L-arabinose from xylose mother liquor by yeast-mediated biopurification.PMC3125199Lv JLin SDeng ZWang HJiang MCheng HfalseA novel method to prepare L-arabinose from xylose mother liquor by yeast-mediated biopurification.<h4>Background</h4>L-arabinose is an important intermediate for anti-virus drug synthesis and has also been used in food additives for diets-controlling in recent years.
