Profiling protein hydrolysis and amino acid metabolism in camel and bovine milk fermented by Lactobacillus helveticus, L. bulgaricus, and Streptococcus thermophilus.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fermented milk has received significant attention due to its multiple health benefits. The fermentation of milk is a complex and dynamic process that is greatly affected by the selection of the starter cultures. This study examined the impacts of mono- and co-fermentation involving Lactobacillus helveticus, L. delbrueckii subsp. bulgaricus, and Streptococcus salivarius subsp. thermophilus on proteolysis and amino acid metabolism in camel milk (CM) and bovine milk (BM). Fermentation of CM was accompanied by more degradation of caseins and formation of free amino groups compared with BM. Two-way ANOVA analysis showed that residual caseins and free amino group content are affected by bacteria, milk type, and their interactions (p < 0.001). Metabolomic analysis revealed variations in the amino acid metabolites between CM and BM including 12 free amino acids, 13 dipeptides, 12 tri- and higher peptides, and 7 lactoyl amino acids. Importantly, proline-rich peptides, known for their angiotensin-converting enzyme (ACE) inhibitory activity, were more abundant in CM and BM fermented with L. helveticus. These insights into milk differences and proteolytic system variations across bacterial cultures support the selection of strains with enhanced metabolic potential for fermented functional foods.
