PROCESS FOR PRODUCING 1,4-DIHYDOXY-2-NAPHTHOIC ACID

摘要

A process for producing 1,4-dihydoxy-2-naphthoic acid, characterized by starting to culture 1,4-dihydoxy-2-naphthoic acid producing bacterium belonging to propionic acid bacteria under anaerobic conditions and when the concentration of carbon sources in the culture medium has become 3.5 mass% or below, conducting culturing while aerating the culture medium.
