Molecular and bioengineering strategies to improve alginate and polydydroxyalkanoate production by Azotobacter vinelandii
Several aspects of alginate and PHB synthesis in Azotobacter vinelandii at a molecular level have been elucidated in articles published during the last ten years. It is now clear that alginate and PHB synthesis are under a very complex genetic control. Genetic modification of A. vinelandii has produced a number of very interesting mutants which have particular traits for alginate production. On...
متن کاملApplication of Experimental Design and Canonical Analysis of Response Surfaces to the Optimization of Poly(3-hydroxyalkanoates) Production by Pseudomonas aeruginosa 42A2
Many attempts to create bio-plastics from renewable resources have been made in recent years. The main aim of these studies has been to develop products competitive with synthetic polymers. Two main strategies have been studied to produce reasonable yields of these polymers: transgenic plant cells1 and the well known bacterial fermentation process.2 Among the various candidates for biodegradabl...
متن کاملAlginate Production by a Mutant Strain of Azotobacter Vinelandii Using Shake Flask Fermentation
The present study describes the improvement of parent strain of Azotobacter vinelandii NRRL-14641 for enhanced alginate production using shake flask fermentation. Results indicated that a mutant A. vinelandii EMS-45 obtained after EMS treatment gave 1.55 fold better alginate productions than that of the parent strain. Different cultural conditions were employed to optimize the polymer productio...
متن کاملThe GacS sensor kinase regulates alginate and poly-beta-hydroxybutyrate production in Azotobacter vinelandii.
Azotobacter vinelandii produces two polymers: the extracellular polysaccharide alginate and the intracellular polyester poly-beta-hydroxybutyrate (PHB). A cosmid clone (pSMU588) from an A. vinelandii gene library diminished alginate production by A. vinelandii mucoid strain ATCC 9046. The nucleotide sequence and predicted amino acid sequence of the locus responsible for the mucoidy suppression ...
متن کاملProduction of polyhydroxybutyrate and alginate from glycerol by Azotobacter vinelandii under nitrogen-free conditions.
Glycerol is an interesting feedstock for biomaterials such as biofuels and bioplastics because of its abundance as a by-product during biodiesel production. Here we demonstrate glycerol metabolism in the nitrogen-fixing species Azotobacter vinelandii through metabolomics and nitrogen-free bacterial production of biopolymers, such as poly-d-3-hydroxybutyrate (PHB) and alginate, from glycerol. Gl...
