Strain S12-2-1T was isolated from a soil sample collected in the Gyeongsangnam-do province of the Republic of Korea. The isolate is a Gram-stain-negative, aerobic, short, rod-shaped bacterium, and its colonies are red to pink in colour. Analysis of the 16S rRNA gene identified strain S12-2-1T as a member of the genus Hymenobacter in the family Cytophagaceae, with high levels of 16S rRNA gene sequence similarity to Hymenobacter arizonensis OR362-8T (97.7 %), Hymenobacter sedentarius DG5BT (97.4 %) and Hymenobacter humi DG31AT (97...

The effect of milking menaquinone-7 (MK 7) with biocompatible organic solvents on MK 7 production in B. subtilis fermentation was studied. Periodic milking of MK-7 from the fermentation medium by n-hexane significantly enhanced the total MK 7 production ~ 1.7 fold at the end of 72 hours of fermentation (p < 0.05) as compared to the control medium. Milking of MK 7 with a mixture of n-hexane phase modified with n-butanol was also explored. Although milking of MK-7 by a mixture of n-hexane and n-butanol (1:2, v/v), was found to be appropriate in terms of high extraction capacity, no significant increase in total MK-7 concentration was observed...

Rapid, global technological development has caused the food industry to use concentrated food component sources like dietary supplements ever more commonly as part of the human diet. This study analysed the menaquinone-7 (MK-7) content of dietary supplements in oil capsule and hard tablet forms. A novel method for separating and measuring geometric isomers of MK-7 in dietary supplements was developed and validated. Eleven different isomers of cis / trans- menaquinone-7 were identified. Identification of cis / trans isomers was performed by combination of HPLC, UPLC and HRMS-QTOF detection, whereas their quantities were determined by DAD detection...

Urolithins are gut microbial metabolites that exert health benefits in vivo and are generated from ellagic acid (EA) and ellagitannin-containing foods such as strawberries, pomegranates and walnuts. Gordonibacter species produce some intermediary urolithins but the micro-organisms responsible for the transformation of EA into the final and more bioactive urolithins, such as urolithin A and isourolithin A, are unknown. We report here a new bacterium, capable of metabolizing EA into isourolithin A, isolated from healthy human faeces and characterized by determining phenotypic, biochemical and molecular methods...

BASIK2 is a prospective, double-blind, randomized placebo-controlled trial investigating the effect of vitamin K2 (menaquinone-7;MK7) on imaging measurements of calcification in the bicuspid aortic valve (BAV) and calcific aortic valve stenosis (CAVS). BAV is associated with early development of CAVS. Pathophysiologic mechanisms are incompletely defined, and the only treatment available is valve replacement upon progression to severe symptomatic stenosis. Matrix Gla protein (MGP) inactivity is suggested to be involved in progression...
