Engineering a platform for photosynthetic isoprene production in cyanobacteria, using Synechocystis as the model organism

Lindberg, Pia, Park, Sungsoon, Melis, Anastasios·2010·Metabolic Engineering

Abstract

The concept of "photosynthetic biofuels" envisions application of a single organism, acting both as photo-catalyst and producer of ready-made fuel. This concept was applied upon genetic engineering of the cyanobacterium Synechocystis, conferring the ability to generate volatile isoprene hydrocarbons from CO(2) and H(2)O. Heterologous expression of the Pueraria montana (kudzu) isoprene synthase (IspS) gene in Synechocystis enabled photosynthetic isoprene generation in these cyanobacteria. Codon-use optimization of the kudzu IspS gene improved expression of the isoprene synthase in Synechocystis. Use of the photosynthesis psbA2 promoter, to drive the expression of the IspS gene, resulted in a light-intensity-dependent isoprene synthase expression. Results showed that oxygenic photosynthesis can be re-directed to generate useful small volatile hydrocarbons, while consuming CO(2), without a prior requirement for the harvesting, dewatering and processing of the respective biomass.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
