2. Production of 5-ketogluconic acid using recombinant strains of Gluconobacter oxydans
University essay from Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)Abstract : 5-Keto-D-gluconic acid (5-KGA) is a valuable compound that has a wide range of applications in the chemical and food industries and is commonly used as a precursor for manufacturing tartaric acid (TA). Industrial production of 5-KGA through chemical approaches was practiced in the early 1920’s and was dropped immediately due to several drawbacks because of its complicated process that resulted in lower 5-KGA yield and higher accumulation of impure gluconic acid.

5. Construction and Characterization of 3rd Generation Saccharomyces cerevisiae Strains for PHB production form Xylose
University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/BioteknikAbstract : Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. READ MORE
