Abstract

fetched live from OpenAlex

Bacteriophage (phage) isolation from various environmental sources is an important step in identifying phages suitable for therapeutic and/or research purposes. Most published protocols outlining phage isolation techniques focus on the identification and/or characterization of strictly lytic phages. Here, a simple, adapted protocol specific for the isolation of non-lytic, filamentous phages is described. This method can be used in laboratories with access to basic microbiological equipment. Briefly, the adapted protocol steps involve:•Phage enrichment with F-pilus expressing bacterial host and sewage filtrate•Dilution and agar overlay plating of enriched culture•Selection of hazy, turbid plaques followed by screening via PCR.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
