Abstract

The present invention relates to Burkholderia agladiolus A1‑07 and its application in preparing ferulic acid. The preparation method of ferulic acid comprises the steps of preparing crude enzyme powder, hydrolyzing oryzanol and separating. The oryzanol conversion rate of the ferulic acid preparation method of the present invention reaches 67%, the yield of the preparation method can reach more than 56%, and the purity of the obtained ferulic acid product is 22-31% by weight. Therefore, the ferulic acid preparation method of the present invention is easy to operate, high in production efficiency, friendly to the environment, and has good industrial application prospects.

Description

【Technical field】 [0001] The invention belongs to the technical field of microorganisms. More specifically, the present invention relates to Burkholderia gladioli A1-07 and its use in the preparation of ferulic acid. 【Background technique】 [0002] Ferulic acid, whose chemical name is 4-hydroxy-3-methoxycinnamic acid, is a derivative of cinnamic acid, which widely exists in the plant cell wall skeleton, and mostly exists as an ester structure in nature. Ferulic acid has good pharmacological and biological activities, so it is of high value in medicine, health care products, and cosmetic raw materials. [0003] Oryzanol is a mixture of cycloartenyl ferulic acid esters and sterol ferulic acid esters. It is very rich in the by-products of rice bran oil refining. It has been produced by mature technology and has been industrialized in China. [0004] There are currently several methods of preparing ferulic acid. The hydrolysis method is to hydrolyze the angelica, wheat bran, ...
