Technological Potential of Indigenous Lactic Acid Bacteria for Controlled Fermentation of Claclo (An Ivorian Ripe Plantain Fritter)
Bibliographic record
Abstract
Claclo is a traditional Ivorian fritter made from fermented ripe plantain, whose quality often varies due to uncontrolled fermentation practices. This study aimed to select lactic acid bacteria (LAB) with potential as starter cultures for standardizing claclo production. A total of 22 LAB strains were isolated from raw cow’s milk, fermented cassava mash, and cashew apple juice using standard microbiological methods. Macroscopically, colonies were smooth, beige or white, and varied in size. Microscopically, all isolates were Gram-positive, catalase-negative, and mainly coccobacilli or cocci arranged in chains or clusters, consistent with typical morphological traits of Lactobacillus, Leuconostoc, and Pediococcus, though genus confirmation would require molecular identification. The strains were mesophilic, growing optimally at 30–45 °C, tolerating up to 6.5% NaCl, and showing better growth at pH 9 than pH 4. Nine robust strains were selected for proteolytic activity, and three (LBL5, LBM2, LBC2) were tested in plantain mash fermentation. Strain LBL5 (from raw milk) showed rapid acidification (pH 4.0 in 8 h), high titratable acidity (145 meq/100 g), and growth up to 5×10⁸ CFU/g, with total soluble solids reduced from 19.8 to 6.5 °Brix. LBM2 and LBC2 exhibited slower acidification (final pH ≈ 4.4, titratable acidity 92–95 meq/100 g). These results highlight LBL5 as a promising starter culture for claclo, with potential to improve safety and shelf life while valorizing local microbial biodiversity.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
