Metabolic engineering of Deinococcus radiodurans for pinene production from glycerol.
Article in Microbial cell factories, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe objective of this work was to engineer Deinococcus radiodurans R1 as a microbial cell factory for the production of pinene, a monoterpene molecule prominently used for the production of fragrances, pharmaceutical products, and jet engine biofuels. Our objective was to produce pinene from glycerol, an abundant by-product of various industries.
resultsTo enable pinene production in D. radiodurans, we expressed the pinene synthase from Abies grandis, the geranyl pyrophosphate (GPP) synthase from Escherichia coli, and overexpressed the native 1-deoxy-D-xylulose 5-phosphate synthase. Further, we disrupted the deinoxanthin pathway competing for the substrate GPP by either inactivating the gene dr0862, encoding phytoene synthase, or substituting the native GPP synthase with that of E. coli. These manipulations resulted in a D. radiodurans strain capable of producing 3.2 ± 0.2 mg/L pinene in a minimal medium supplemented with glycerol, with a yield of 0.13 ± 0.04 mg/g glycerol in shake flask cultures. Additionally, our results indicated a higher tolerance of D. radiodurans towards pinene as compared to E. coli.
conclusionsIn this study, we successfully engineered the extremophile bacterium D. radiodurans to produce pinene. This is the first study demonstrating the use of D. radiodurans as a cell factory for the production of terpenoid molecules. Besides, its high resistance to pinene makes D. radiodurans a suitable host for further engineering efforts to increase pinene titer as well as a candidate for the production of the other terpenoid molecules.
