Phytochemical and functional characterization of fermented Yerba mate using Rhizopus oligosporus.

Solid-state fermentation (SSF) was used to enhance the bioactive compounds and biological properties of food materials, such as buckwheat, turmeric, and ginseng. This study was investigated the effects of SSF for up to 10 days using Rhizopus oligosporus on Yerba mate (Ilex paraguariensis St. Hilaire).

Characterization of Natural Compounds as Inhibitors of NS1 Endonuclease from Canine Parvovirus Type 2.

Canine parvovirus type 2 (CPV-2) has high morbidity and mortality rates in canines. Nonstructural protein 1 (NS1) of CPV-2 has endonuclease activity, initiates viral DNA replication, and is highly conserved. Thus, it is a promising target for antiviral inhibitor development.

Synthesis and biological characterization of low-calorie syrup.

Unlabelled: (Omija) is a well-known medicinal plant in East Asia. In this study, Omija oligosaccharide syrup was prepared from sucrose with Omija fruit extract using two glucansucrases of B-512F/KM and B-1355CF10/KM. The degree of polymerization of Omija oligosaccharide syrup was ranged from 2 - 13 by MALDI-TOF-MS analysis.

Enhancement of the water solubility and antioxidant capacities of mangiferin by transglucosylation using a cyclodextrin glycosyltransferase.

This study aimed to enhance the water solubility and antioxidant properties of mangiferin by transglucosylation using cyclodextrin glycosyltransferase (CGTase) from Thermoanaerobacter sp. The highest mangiferin to mangiferin glucoside conversion yield achieved was 88.9% using 60 mU/mL CGTase, 25 mM mangiferin, and 10% starch (w/v), with incubation at 60 °C for 10 h.

Enzymatic synthesis and biological characterization of a novel mangiferin glucoside.

Mangiferin, a major constituent of Mangifera indica L., has attracted substantial attention due to its anti-oxidant, anti-diabetic, anti-inflammatory, and anti-microbial activities. However, its poor solubility in water limits its use in food and pharmaceutical industries.

Synthesis and characterization of stevioside having low degree polymerized glucosides using dextransucrase and dextranase.

Transglycosylation is one of enzymatic methods to improve the physical and biochemical properties of various functional compounds. In this study, stevioside glucosides were synthesized using sucrose as a substrate, stevioside (Ste) as an acceptor, and dextransucrase from Leuconostoc mesenteroides B-512 F/KM. The highest Ste conversion yield of 98% was obtained with 50 mg/mL Ste, 800 mM sucrose, and dextransucrase 4 U/mL at 28 °C for 6 h.

The use of fermented buckwheat to produce L-carnitine enriched oyster mushroom.

L-Carnitine is an essential compound that shuttles long chain fatty acids into mitochondria. The objective of this study was to produce L-carnitine enriched oyster mushroom (Pleurotus ostreatus) using common buckwheat fermented by Rhizopus oligosporus. Mushroom grown on common buckwheat medium contained 9.

Decrease of insoluble glucan formation in Streptococcus mutans by co-cultivation with Enterococcus faecium T7 and glucanase addition.

Objectives: To develop preventive canine oral health bio-materials consisting of probiotics and glucanase to reduce insoluble glucan and volatile sulfur compound formation.

Results: Co-cultivation of Enterococcus faecium T7 with Streptococcus mutans at inoculation ratio of 3:1 (v/v) resulted in 25% reduction in the growth of Streptococcus mutans. Amounts of soluble and insoluble glucans produced by S.
