Abstract: 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.

Abstract: The present invention relates to a method for microbial fermentation and biotransformation of aromatic acids to aromatic acids with reduced carbon atoms of wide commercial importance using a culture of actinomycete species. Amycolatopsis sp or the mutant thereof is employed in the present invention to convert natural as well as synthetic aromatic acids to reduced carbon aromatic acids with wide applications. The said culture in the disclosed invention is adapted to grow at 37-46° C. to achieve the biotransformation of aromatic acid to reduced carbon aromatic acid is accomplished at 37-46° C. to obtain a higher yield of the product.
