Fermentation of Carrot Juice by Probiotics: Viability and Preservation of Adhesion
Bibliographic record
Abstract
Abstract: In the present work, carrot juice was investigated as an alternative carrier for probiotics. Pasteurized juice was fermented anaerobically over night at 37 o C with selected probiotics and their viability was assessed after 1, 2, 4, 8 and 12 week storage. Identification was performed by species specific PCR. Mucus adhesion was assessed of carrot juice and laboratory medium grown Lactobacillus strains. At inoculation, the probiotic strains were present at levels of 10 6 -10 7 CFU/ml and during fermentation the lactobacilli numbers increased to 10 9 -10 10 CFU/ml. After four weeks storage, Lactobacillus levels remained almost unchanged and after 12 weeks there were still 10 7 -10 9 CFU/ml lactobacilli. Bifidobacteria, however, did not grow and started to decline after two weeks and were undetectable after 8 weeks. Adhesion of carrot juice grown lactobacilli was 50-70% less then adhesion of the strains grown in laboratory medium. The results suggest that fermented carrot juice is a promising carrier for probiotic lactobacilli but not bifidobacteria, but may alter the phenotypic properties of lactobacilli.

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.
