Abstract

fetched live from OpenAlex

Abstract Pullulan is a water‐soluble polysaccharide produced through fermentation withAureobasidium pullulans. Pullulan has been used as specialty food for decades in Japan. Owing to its relatively high price, recent developments on pullulan are mainly focused on its application in biomedical engineering and pharmaceutical industry. Both laboratory and commercial pullulan production methods are reviewed. Among several problems associated with pullulan fermentation, the highly viscous fermentation broth remains the biggest challenge. The viscous non‐Newtonian broth creates major difficulties in mixing, oxygenation, process monitoring, sampling, and downstream product recovery. Many approaches to improve the fermentation efficiency have been attempted. One promising method is to use close clearance impellers, such as reciprocating plate mixer, instead of standard Rushton turbines in order to achieve more uniform mixing. Other unconventional techniques, such as cell immobilization, hyperbaric fermentation, and nonsterile fermentation, have also been discussed. However, these technologies need more research and investigation before they can be implemented at an industrial scale.

Not 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.
