Engineered strain of Escherichia coli for production of poly-R-3-hydroxyalkanoate polymers with defined monomer unit composition and methods based thereon
Methods and systems for producing prescribed unit size poly(3-hydroxyalkanoate) (PHA) polymers and copolymers are provided. The methods and systems can employ recombinant bacteria that are not native producers of PHA or lack enzymes to degrade PHA once synthesized, metabolize short to long chain fatty acids without induction, and express an (R)-specific enoyl-CoA hydratase and a PHA synthase, the (R)-specific enoyl-CoA hydratase and PHA synthase having wide substrate specificities. The recombinant bacteria are fed at least one fatty acid substrate that is equal in carbon length to the prescribed or desired unit size of the PHA polymer to be produced. The prescribed unit size PHA that is produced is then isolated and/or purified. |

Microalga having aggregation ability
In ethyl alcohol production using the self-fermentation of a microalga, a step of concentrating or collecting an algal body by centrifugal treatment, filtering treatment or the like is made unnecessary or simple to save labor for effort and equipment therefor is saved. The microalga belongs to Chlamydomonas sp., and is a variant strain which has an ability to produce ethyl alcohol under dark and anaerobic conditions and has acquired an ability to proliferate while aggregating. The microalga is proliferated and maintained under dark and anaerobic conditions to generate ethyl alcohol in this method for producing ethyl alcohol. |

Compositions and methods for deploying a transgenic refuge as a seed blend
Methods and compositions for deploying refuge seeds together with transgenic crop seeds are provided. The refuge seeds can be non-transgenic seeds of a similar variety to that of the transgenic crop seeds, or the refuge seeds can be a transgenic variety, but in either case lacking a transgenic trait conferring pest protection found in the transgenic crop seeds. |
