Pathways for accelerated bacterial spore killing with ohmic heating.
Article in NPJ science of food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The mechanism by which ohmic heating (OH) accelerates bacterial spore killing compared to conventional heating (CH) is unclear. This study used genetically modified Bacillus subtilis spores to investigate OH's impact on specific components. Flow cytometry assessed membrane integrity, and molecular dynamics (MD) simulations examined the DNA-SASP complex under an electric field. Among the inner membrane (IM) proteins (YetF, YdfS, and YkjA) tested for its resistance against OH and CH, YeTF was found to be the most significant contributor to spore resistance for both treatments. SASP, SpoVA proteins, and Ca-DPA interacted with the field, showing specific effects at certain temperature and field intensity combinations. Flow cytometry showed spore staining with propidium iodide (PI), which increased with higher field intensities, indicating significant IM damage. MD simulations showed that the electric field caused the SASP-DNA complex to dissociate, with greater separation at higher field intensities. Thus, OH accelerates spore killing by affecting key IM and core molecules.
