High-efficiency depolymerization/degradation of polyethylene terephthalate plastic by a whole-cell biocatalyst.
Article in 3 Biotech, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Polyethylene terephthalate (PET) is the most abundantly produced plastic due to its excellent performance, but is also the primary source of poorly degradable plastic pollution. The development of environment-friendly PET biodegradation is attracting increasing interest. The leaf-branch compost cutinase mutant ICCG (F243I/D238C/S283C/Y127G) exhibits the best hydrolytic activity and thermostability of all known PET hydrolases. However, its superior PET degradation is highly dependent on its preparation as a purified enzyme, which critically reduces its industrial utility. Herein, we report the use of rational design and combinatorial mutagenesis to develop a novel ICCG mutant RITK (D53R/R143I/D193T/E208K) that demonstrated excellent whole-cell biocatalytic activity. Whole cells expressing RITK showed an 8.33-fold increase in biocatalytic activity compared to those expressing ICCG. Thermostability was also improved. After reacting at 85 °C for 3 h, purified RITK exhibited a 12.75-fold increase in depolymerization compared to ICCG. These results will greatly enhance the industrial utility of PET hydrolytic enzymes and further the progress of PET recycling.
