Objective: The purpose of the study was to generate information on the safety of probiotics, thus the study objectives were to evaluate the effects of Yoba® on basic physiochemical properties. The study assessed male w1118 Drosophila melanogaster which were provided food supplemented with Yoba® at 1%, 3%, 6%, and 12% on motor function, total protein, catalase activity, and hydrogen peroxide scavenging activity and lifespan.

Results : Yoba® at high concentration (??6%) increased locomotor activity in Drosophila melanogaster, however, total protein, catalase, and hydrogen peroxide scavenging activity were significantly higher at 1% Yoba® compared to 3%, 6%, and 12% Yoba®. Yoba consumed at 1% was associated with greater physiological benefits in Drosophila melanogaster. Findings in the study offer a rationale for the consumption of Yoba® at 1% in humans as is currently being promoted by the Yoba for Life consortium, however, high concentrations of Yoba® would disrupt physiological function as shown by this study.
