Abstract
聚羟基脂肪酸酯（PHAs）是微生物在不平衡生长状态下作为胞内碳源和能源被储存的一种高分子聚合物，可以用一系列的可再生原料和生物方法来生产，具有生物降解性和生物相容性等特点，可以代替某些传统的石化塑料，应用前景广阔。目前，工业上生产PHAs主要利用野生型和重组型微生物的发酵来进行，而混合培养和转基因植物生产PHAs也因其成本低廉等优点受到越来越广泛的关注。文中主要对近年来生物合成聚羟基脂肪酸酯（PHAs）的研究进展进行总结，以期为聚羟基脂肪酸酯的工业化生产及进一步的开发利用提供依据。

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.
