Abstract
Description of the subject. Variability observed in sensory characteristics of “attiéké” results from an uncontrolled fermentation process due to the use of artisanal starters. Objectives. This study aims to screen microbial strains for their use during fermentation of cassava dough into attieké. Method. Technological properties of three lactic acid bacteria (LAB) isolated from artisanal starters were highlighted in vitro, and these LAB were identified as either Weissella cibaria or Weissella confusa by Matrix Assisted Laser Desorption Ionisation-Mass Spectrometry (MALDI-TOF MS). Results. The three Weissella isolates Wc 69, Wc 21 and Wc 114 induced in less than 42 h a decrease below 4.2 (main food safety factor) of the initial pH of MRS (de Man, Rogosa and Sharpe) broth. These strains are osmotolerant, present alpha-amylase activity and ferment the indigestible sugar raffinose. Moreover isolates Wc 114 and Wc 69 are thermotolerant, while Wc 114 presents a pectinase activity necessary for cassava dough softening. Conclusions. Considering their technological properties, the three isolated Weissella strains could be suitable in optimizing and standardizing the quality of attieké.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
