Bacterial biosynthesis of abietane-type diterpene ferruginol from glucose.
Article in Microbial cell factories, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundMicrobial supply of plant extracts is a promising biomanufacturing strategy that requires engineering of metabolic pathways and enzymes. This study presents the engineering of Corynebacterium glutamicum for heterologous production of diterpenes miltiradiene and ferruginol.
resultsThrough targeted metabolic pathway modifications, including inactivation of pyruvate carboxylase and phytoene synthase, the HL01 strain was optimized to enhance pyruvate and geranylgeranyl pyrophosphate (GGPP) pools. Overexpression of key MEP pathway enzymes (Dxs and Idi) and implementation of three GGPP synthase modules further boosted diterpene synthesis. Then, combining those modules with diterpene synthase (DiTPS) and intact P450 reductase modules (CYP76AH1 and CPR1) enabled production of miltiradiene (ferruginol equivalent) at 237.46 ± 34.8 mg/L and ferruginol at 107.34 ± 1.2 mg/L under constant glucose feeding, respectively.
conclusionsModular gene expression for heterologous metabolic pathway can be optimized for bacterial biosynthesis. This is the first demonstration of ferruginol production in bacteria. These findings pave the way for further optimization of diterpene biosynthesis through pathway engineering and module integration in bacterial systems.
