The present invention discloses a novel method for biological reduction of the carboxylic acids to their corresponding aldehydes and/or alcohols with high productivity and high yield by using fungus in the category of basidiomycetes. This reduction is specific and selective for its functional group (—COOH), without affecting other functional group such as—R groups (—OH, —NH2, -alkyl, -alkyoxy) and their position, number on aromatic ring. The method of the invention relates to reduction of aryl acids to aldehyde and/or alcohols by employing a white rot fungus—
Pycnoporus cinnabarinus
, an organism of basidiomycete species, grown in vessel/column. The biotransformation was performed in vessel/column/fermentor with pH control, dissolved oxygen, membrane system, product extractor is attached.
本发明揭示了一种新的生物还原羧酸为相应的醛和/或醇的方法,该方法利用属于担子菌类真菌的真菌具有高产量和高收率。该还原对其官能团(-COOH)具有特异性和选择性,不会影响其他官能团,例如-R基团(-OH,-NH2,-烷基,-烷氧基)及其在芳香环上的位置和数量。本发明的方法涉及使用白腐菌-Pycnoporus cinnabarinus将芳基酸还原为醛和/或醇,该真菌属于担子菌物种,生长在容器/柱中。生物转化在具有pH控制,溶解氧,膜系统和附加产品提取器的容器/柱/发酵罐中进行。
