Characterization of microorganisms following dairy keeping quality tests in Québec
Bibliographic record
Abstract
: Despite best efforts of the dairy industry, premature spoiling and non-compliance of products remain problematic and cause economic loss. In this study, 190 dairy products/samples of the Québec province were analyzed using governmental quality tests and keeping quality tests, such as the Virginia Tech. procedure, the Moseley test and a Paenibacillus test, to allow identification, by 16S sequencing, and characterization of the microorganisms causing non-compliance. We found that the Paenibacillus test isolated mostly Bacillus and Paenibacillus whereas the other tests isolated primarily Pseudomonas . Tests in 96-well assay plates showed that Pseudomonas had the most moderate to strong biofilm forming ability producers. Except for four isolates of Pseudomonas and one isolate of Stenotrophomonas chelatiphaga , biofilm producers were sensitive to both sodium hypochlorite and peracetic acid at concentrations typically used to disinfect dairy equipment. This study will help in the development of control strategies targeting problematic bacterial contaminants in the dairy sector.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
