Overproduction of clavulanic acid by extractive fermentation

Electronic Journal of Biotechnology, 2015
Background: Clavulanic acid is an important beta-lactamase inhibitor produced as a secondary metabolite by the actinomycete Streptomyces clavuligerus. Clavulanic acid is chemically unstable; therefore, it is degraded during bacterial cultivation. In this
