Biobutanol Production Using High Cell Density Fermentation in a Large Extractant Volume

International Journal of Renewable Energy Development, 2020
Biobutanol is well known as a suitable substitute for gasoline, which can be applied without engine modification. Butanol toxicity to the producer strain causes difficulties to grow strain of higher than 4 g/L dry cell weight and to produce butanol ...

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
