Functional fermented fruit juices produced using a combination of non- yeast and lactic acid bacteria (LAB) are relatively unexplored. The effects of three inoculation protocols, single inoculation with (), single inoculation with (), and co-culture of both + , on the physicochemical, microbiological, sensory properties, and metabolic profile of fermented JA juices after 24 h at 30 °C were investigated. Uninoculated (UI) Japanese apricot (JA) juice was used as a control.

The in vitro antioxidant and enzyme inhibitory effects of SPW hydrolysates obtained from the fermentation process were investigated. SPW broths were prepared from the head (SPW-SH) and body carapace (SPW-SS) of Pacific white shrimp () and fermented using a 5-day successive co-culture fermentation approach with TISTR-1880 and TBRC-388.

However, only six isolates were selected for further extensive studies based on the strength of their antimicrobial activities and their tolerance against simulated gastrointestinal conditions.

We previously developed the synbiotic mulberry (SM) containing probiotic Lactobacilli, prebiotic inulin, and mulberry powder. In food supplement development, toxicity is the most important criterion in food and drug regulations before commercialization.

However, the main drawback of this approach is that yeast can only partially remove sucrose from crude FOSs. The main objective of this research was to screen yeast strains for the capability of selectively consuming unwanted sugars, namely fructose, glucose, and sucrose, in crude FOSs extracted from red onion (Allium cepa var.

MR10 for further application in the fermentative production of manno-oligosaccharides (MOS) from agricultural by-product, defatted copra meal (DCM). The mutants obtained were screened based on their defective lipase activity together with their β-mannanase production performance.

The rate constants or partitioning ratios (kNu/kwater) determined for these different acceptors (termed nucleophiles, Nu) were used as a measure for the ability of a certain substance to act as a galactosyl acceptor of these β-galactosidases.
