Immobilization of Paenibacillus polymyxa with biopolymers to enhance the production of 2,3-butanediol.

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
backgroundPaenibacillus polymyxa, is a Gram-positive, plant growth promoting bacterium, known for producing 98% optically pure 2,3-butanediol, an industrially valuable chemical for solvents, plasticizers and resins. Immobilization of Paenibacillus polymyxa has been proposed to improve the cell stability and efficiency of the fermentation process, reduce contamination and provide easy separation of butanediol in the culture broth as compared to conventional bioprocesses. This research aimed to explore the potential of Paenibacillus polymyxa with immobilization technique to produce 2,3-butanediol.
resultsWe investigated different immobilization methods with natural biopolymers like alginate, chitosan and carrageenan-chitosan-based immobilization. These methods were further investigated for their immobilization efficiency and yield in 2,3-butanediol production. Carrageenan-chitosan beads enabled a higher cell concentration and demonstrated superior cell retention to calcium-alginate-chitosan beads. Carrageenan-chitosan immobilization preserved 2,3-butanediol production in bacteria and increased the product formation rate.
conclusionCarrageenan-chitosan immobilization enables non-pathogenic Paenibacillus polymyxa to be a capable 2,3-butanediol producer with increased product formation rate, which has not been previously reported. This novel strategy offers promising alternative to traditional fermentation processes using pathogenic strains and can be further applied in co-cultivations for metabolite production, wastewater management and bioremediation.
