Abstract

fetched live from OpenAlex

Growth patterns of four different serovar of Bacillus thuringiensis (Bt) (Bt kurstaki, Bt israelensis, Bt tenebrionis, and Bt aizawai) were studied using wastewater sludge as a raw material. A comparative study using synthetic medium (soy) was also performed. It was observed that the four Bt strains gave cell counts of the order of 108CFU∕mL in wastewater sludge and 109CFU∕mL in synthetic medium. The sporulation (% spores) in two media was 90%. The entomotoxicity per unit spore (specific entomotoxicity) was much higher in sludge medium compared to synthetic medium. Therefore, sludge was a good source of nutrients for growth and toxin production by all types of serovar used in this study.

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.
