Abstract

fetched live from OpenAlex

Five marine bacteria ("Pseudoalteromonas spiralis", Te-2-2; "Pseudoalteromonas telluritireducens", Se-1-2-red; "Erythrobacter litoralis", T4; "Citromicrobium bathyomarinum", JF1; and a "Shewanella frigidimarina relative", strain ER-Te-48), possessing both very high level aerobic resistance and the ability to reduce TeO_3^(2-) to elemental Te were investigated to better understand their interaction with this metalloid oxide. It was found that reduction can be greatly influenced by several factors including carbon source, pH and aeration. The physiological and metabolic response of cells to tellurite differs between strains. In its presence, versus absence, cellular biomass varied, yielding relatively similar or decreased amounts of protein. ATP production was affected in the same manner, with similar and decreased levels in cells harvested from media containing TeO_3^(2-). Three different strategies for tellurite reduction, which required de novo synthesis of a reductase, were observed. Strain ER-Te-48 employed a periplasmic reductase, while Te-2-2, T4 and JF1 required an intact cytoplasmic membrane for reduction. Lastly, Se-1-2-red was only able to reduce as an undisturbed whole cell culture.

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.
