The Influence of Short Chain Fatty Acids on Biosynthesis of Emodin by Aspergillus ochraceus LP-316

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 269)

Abstract

Emodin or 1,3,8-trihydroxy-6-methyl-anthraquinone is a naturally occurring pigment found in many plants, molds and lichens. Our previous studies revealed that a strain of Aspergillus ochraceus LP-316 (from LP-118 isolated from Chinese potato) had produced emodin efficiently. In this article, the production of emodin in 5-L bioreactor and resting cells system was studied with adding short chain fatty acids as precursors in order to identified the biosynthesis pathway type of emodin. The result illustrated that acetic acid was propitious to enhance the content of emodin and provided valuable information for the further searching the biosynthesis mechanism of emodin.
