Overproduction of clavulanic acid by extractive fermentation [PDF]

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

Development of In Situ Product Recovery (ISPR) System Using Amberlite IRA67 for Enhanced Biosynthesis of Hyaluronic Acid by Streptococcus zooepidemicus

Life, 2023
High broth viscosity due to the accumulation of hyaluronic acid (HA) causes a limited yield of HA. It is a major problem of HA production using Streptococcus zooepidemicus.

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 ...

Design Process of Ethanol Production by Extractive -Fermentation to Increase The Yield and Productivity of Ethanol [PDF]

, 2012
Ethanol is generally produced by batch fermentation process. However, this process will bring about accumulation of ethanol product which can poison the microorganism and lead to low productivity which finally results in an economical disadvantage.
