Summary A fluorescence fingerprint (FF) was used to develop a quick and non-contact practical method for predicting the sensory evaluation index of cheese texture (cheese body measurements). A partial least squares model was constructed from FF data and cheese body measurements of Cheddar cheeses. The cheese body measurement was successfully predicted by the PLS model with a coefficient of determination for calibration of 0.800.

Summary Sharing of Bifidobacterium longum strains had recently been shown to occur among Japanese family members, a phenomenon that is not confined to mother-infant pairs. In the current study, we investigated if bathtub water is a possible vehicle for the exchange of strains as a consequence of a Japanese custom to share bathtub water by family members during bathing practices. Viable bifidobacterial strains were isolated from all bathtub water samples. We showed that the fecal microbiota composition among family members that share bathtub water is significantly closer than that between family members that do not engage in this practice. Our results indicate that bathtub water represents a vehicle for the transmission of gut bacteria, and that the Japanese custom of sharing bathtub water contributes to the exchange of gut microbes, in particular bifidobacteria, among family members.

Summary The effects of heat-killed Lactobacillus paracasei MCC1849 (LAC-Shield™) on the common cold and mood states during winter in healthy adults were evaluated in a randomised, double-blind, placebo-controlled trial. In a subgroup of subjects susceptible to the common cold, the incidence and symptom scores of the common cold significantly improved in the 10 billion cell MCC1849-intake group. The results of this study indicate that paraprobiotic L. paracasei MCC1849 has the potential to improve resistance to common cold infections and maintain a desirable mood state, even under mental stress conditions.

Summary We performed a comparative genome analysis of Bifidobacterium longum subsp. longum to unravel the reason why this subspecies are widely distributed across all generation. As results, a broad distribution of them across the human lifespan is due to a high transfer level between family members. We furthermore identified a variety of genes which could enhance their adaptation and increase competitiveness in the gut environment, enriched in genomes corresponding to specific ages.

Summary Use of slightly acidic hypochlorous acid water (PURESTER-generated water) to irrigate strawberry seedlings revealed that it had an effect for reducing infection with anthracnose, a major disease with a strong bearing on cultivation. In addition, because there was no detectable adverse influence on growth, it is thought that slightly acidic hypochlorous acid water could be effectively used for irrigation of strawberry seedlings.
