BSH-1 is an O‑acetyl-arabinoxylan obtained from bamboo shavings. This study investigated its fermentation behavior by human colonic bacteria in vitro. Results showed that BSH-1 remarkably modulated the composition of colonic microbiota, mainly by increasing the growth of potential beneficial genera (i.e. Bifidobacterium, Lactobacillus, Bacteroides, Prevotella_7, Parabacteroides) and by decreasing the growth of potential harmful genera (i.e. Fusobacterium, Lachnospiraceae_UCG-008, Bilophila and Desulfovibrio). BSH-1 significantly promoted the production of short-chain fatty acids, especially acetic, propionic and n-butyric acids. After 48 h fermentation, the concentration of n-butyric acid in BSH-1 fermentation culture was increased by 2.41 times compared to the blank. During fermentation, the activity of acetyl xylan esterase, arabinofuranosidase, xylanase and xylosidase was enhanced. Moreover, free arabinose, xylose, xylobiose, xylotriose, xylotetraose, xylopentaose and xylohexaose were detected. These results suggest that BSH-1 could potentially be a functional ingredient to improve gut health.

The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.

An enzyme that catalyzes the formation of acetoacetyl-CoA from two molecules of ACETYL COA. Some enzymes called thiolase or thiolase-I have referred to this activity or to the activity of ACETYL-COA C-ACYLTRANSFERASE.
A normal intermediate in the fermentation (oxidation, metabolism) of sugar. The concentrated form is used internally to prevent gastrointestinal fermentation. (From Stedman, 26th ed)
An acetyl ester of ADENOSINE DIPHOSPHATE RIBOSE formed during NAD-dependent deacetylation of proteins by SIRTUINS. The acetate group resides on the ribose ring where nicotinamide was cleaved from NAD during the reaction. Several isomers of O-acetyl-ADP-ribose have been isolated from the reaction.
