摘要:
Various 1-alkenes, including 1-nonadecene and 1-octadecene, are synthesized by the engineered microorganisms and methods of the invention. In certain embodiments, the microorganisms comprise a recombinant alpha-olefin-associated enzyme. This enzyme may be expressed in combination with a recombinant alkene synthase pathway-related gene. The engineered microorganisms may be photosynthetic microorganisms such as cyanobacteria.
摘要:
The NonA alkene synthase in Synechococcus sp. displays selective synthesis of 1-nonadecene. Heterologous recombination of a domain, i.e. the acyl binding domain, with other acyl binding proteins, affects acyl substrate chain-length binding selectivity and therefore the chain-length of the synthesized 1-alkenes. Compositions and methods are provided to selectively synthesize 1-alkenes of various chain lengths.

The present invention provides photobioreactors, solar energy gathering systems, and methods for thermal control of a culture medium containing a phototrophic organism in a photobioreactor, that allow temperature control in a cost effective manner, reducing the energy required for temperature control of a culture medium containing phototrophic microorganisms in a photobioreactor.
摘要:
The present disclosure relates to methods and compositions for engineering photoautotrophic organisms to convert carbon dioxide and light into fatty acid esters and other molecules, including biofuels. The molecules are then secreted by the organism into a growth medium.
摘要:
The present invention provides fractional condensation apparatuses, systems and methods that can recover volatile products from highly diluted liquid and vapor feed mixtures with high purity and recovery yield, both in batch and continuous distillation, while being also designed to achieve low-cost and efficient recovery processes. Single apparatuses and columns can be connected to each other to expand or shrink the column length for desired separation. The apparatuses, systems and methods can be applied to separate mixtures with both narrow and wide boiling point ranges.
摘要:
The present disclosure identifies methods and compositions for modifying photoautotrophic organisms, such that the organisms efficiently convert carbon dioxide and light into compounds such as esters and fatty acids. In certain embodiments, the compounds produced are secreted into the medium used to culture the organisms.
