Inactivation of Vegetative Bacteria in a Liquid Medium by Gas Plasma under Atmospheric Pressure
Bibliographic record
Abstract
The bactericidal effect of gas plasma on vegetative bacteria, including Escherichia coli K12, Escherichia coli 0157:H7, Salmon;ella typhimurium or Pseudomonas aerugi?7;osa, in 0.90/0 (w/v) NaCl was investigated under atmospheric pressure. Circumambient air, which had 400/0 relative humidity (r.h.), was introduced into the plasma-generating unit at 7 l/min, and was excited by applying radio frequency discharge (20kHz) to a conductive electrode in the unit. This caused the circumambient air to form atmospheric gas plasma (AGP). By exposing each cell suspension surface to the AGP, 107CFU/tnl of viable reduction was achieved within 15 min in all strains tested. Those survival curves showed a two-step process, a slow process followed by a much faster one. The bactericidal effect was not attributed to ozone. The AGP wlth circumambient air apparently increased the electrical conductivity in deionized water. It is concluded that ions from the AGP was responsible for the bactericidal effect.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
