Global climate change has stimulated efforts to reduce CO2 emissions. One approach to addressing this problem is to recycle CO2 directly into fuels or chemicals using photosynthesis. Here we genetically engineered Synechococcus elongatus PCC7942 to produce isobutyraldehyde and isobutanol directly from CO2 and increased productivity by overexpression of ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco). Isobutyraldehyde is a precursor for the synthesis of other chemicals, and isobutanol… 

Cyanobacterial conversion of carbon dioxide to 2,3-butanediol

This work systematically developed the 2,3-butanediol (23BD) biosynthetic pathway in Synechococcus elongatus PCC7942 as a model system to establish design methods for efficient exogenous chemical production in cyanobacteria, and identified 23BD as a target chemical with low host toxicity.

Biological conversion of carbon dioxide to photosynthetic fuels and electrofuels

Recent advances in developing biofuel production processes from CO2 are discussed, which include photosynthetic processes using algae and cyanobacteria and the non-photosynthetic “electrofuel” processes using Ralstonia eutropha and other lithoautotrophic microorganisms.

Engineering a cyanobacterium as the catalyst for the photosynthetic conversion of CO 2 to

It is demonstrated that cyanobacteria can be engineered as a catalyst for the photosynthetic conversion of CO2 to 1,2-PDO and suggested that they may be useful tools for renewable production of reduced chemicals in Photosynthetic organisms.

Photoautotrophic synthesis of butyrate by metabolically engineered cyanobacteria

The feasibility of photosynthetic butyrate production is demonstrated and the chemical repertoire accessible for production by photoautotrophs is expanded.

Engineering a cyanobacterium as the catalyst for the photosynthetic conversion of CO2 to 1,2-propanediol

This work demonstrated that cyanobacteria can be engineered as a catalyst for the photosynthetic conversion of CO2 to 1,2-PDO, and characterized two NADPH-dependent sADHs for their catalytic capacity in 1,1- PDO formation, and suggested that they may be useful tools for renewable production of reduced chemicals in photosynthetics organisms.



Engineering the isobutanol biosynthetic pathway in Escherichia coli by comparison of three aldehyde reductase/alcohol dehydrogenase genes

Compared the effect of various alcohol dehydrogenases (ADH) for the last step of the isobutanol production, E. coli has the yqhD gene which encodes a broad-range ADH and shows better production than ADH2, a result confirmed by activity measurements with isobutyraldehyde.

Ethanol Synthesis by Genetic Engineering in Cyanobacteria

New genes are introduced into a cyanobacterium in order to create a novel pathway for fixed carbon utilization which results in the synthesis of ethanol, a potential system for bioconversion of solar energy and CO2 into a valuable resource.

Non-fermentative pathways for synthesis of branched-chain higher alcohols as biofuels

This strategy uses the host’s highly active amino acid biosynthetic pathway and diverts its 2-keto acid intermediates for alcohol synthesis to achieve high-yield, high-specificity production of isobutanol from glucose.

CO2 Mitigation and Renewable Oil from Photosynthetic Microbes: A New Appraisal

The only major strategy now being seriously considered for biological mitigation of atmospheric CO2 relies entirely on terrestrial plants. Photosynthetic microbes were the focus of similar

Role of Light Intensity and Temperature in the Regulation of Hydrogen Photoproduction by the Marine Cyanobacterium Oscillatoria sp. Strain Miami BG7

The capacity of cells to evolve oxygen deteriorated with increasing culture age and nitrogen depletion, and the ability of these cells to produce oxygen in closed anaerobic hydrogen production systems was temporally limited.

Hydrogen production by Cyanobacteria

This review highlights the basic biology of cynobacterial hydrogen production, strains involved, large-scale hydrogen production and its future prospects as well as integrating the existing knowledge and technology before hydrogen is accepted as a commercial primary energy source.

Plastid transformation is used to replace RubisCO in tobacco with the simple homodimeric form of the enzyme from the α-proteobacterium, Rhodospirillum rubrum, which has no small subunits and no special assembly requirements, establishing that the activity of a Rubis CO from a very different phylogeny can be integrated into chloroplast photosynthetic metabolism without prohibitive problems.
