Metabolic Engineering of Microorganisms to Increase Production of Violacein

Metabolic Engineering of Microorganisms for the Production of Higher Alcohols

Due to the increasing concerns about limited fossil resources and environmental problems, there has been much interest in developing biofuels from renewable biomass. Ethanol is currently used as a major biofuel, as it can be easily produced by existing fermentation technology, but it is not the best biofuel due to its low energy density, high vapor pressure, hygroscopy, and incompatibility with...

Metabolic engineering of microorganisms: general strategies and drug production.

Many drugs and drug precursors found in natural organisms are rather difficult to synthesize chemically and to extract in large amounts. Metabolic engineering is playing an increasingly important role in the production of these drugs and drug precursors. This is typically achieved by establishing new metabolic pathways leading to the product formation, and enforcing or removing the existing met...

Engineering Corynebacterium glutamicum for violacein hyper production

BACKGROUND Corynebacterium glutamicum was used as a metabolic engineering chassis for production of crude violacein (mixture of violacein and deoxyviolacein) due to Corynebacterium's GRAS status and advantages in tryptophan fermentation. The violacein is a commercially potential compound with various applications derived from L-tryptophan. RESULTS Corynebacterium glutamicum ATCC 21850 that co...

Metabolic engineering strategies to increase n-butanol production from cyanobacteria

The development of sustainable replacements for fossil fuels has been spurred by concerns over global warming effects. Biofuels are typically produced through fermentation of edible crops, or forest or agricultural residues requiring cost-intensive pretreatment. An alternative is to use photosynthetic cyanobacteria to directly convert CO2 and sunlight into fuel. In this thesis, the cyanobacteri...
