The amount of iron in the diet directly influences the composition of the microbiota. Inversely, the effects of the microbiota on iron homeostasis have been little studied. So, we investigate whether the microbiota itself may alter host iron sensing. Duodenal cytochrome b and divalent metal transpor

Occurrence of bacteriophages infecting Bacteroides host strains (ARABA 84 and GB-124) in fecal samples of human and animal origin.

Diston D1, Wicki M2.
Journal of water and health.J Water Health.2015 Sep;13(3):654-61. doi: 10.2166/wh.2014.199.
Bacteriophage-based microbial source-tracking studies are an economical and simple way of identifying fecal sources in polluted water systems. Recently isolated Bacteroides spp. strains ARABA 84, and GB-124 have been shown to detect bacteriophages exclusively in aquatic systems impacted by human fec

Journal of pharmaceutical sciences.J Pharm Sci.2015 Aug 25. doi: 10.1002/jps.24617. [Epub ahead of print]
Chitosan and alginate nano-composite (NP) carriers intended for colonic delivery containing prednisolone and inulin were obtained by two processes. Spray freeze-drying using chitosan (SFDC) or alginate (SFDA) was proposed as an alternative to the traditional chitosan-tripolyphosphate platform (CTPP)

Differences in the Substrate Specificities and Active-Site Structures of Two α-L-Fucosidases (Glycoside Hydrolase Family 29) from Bacteroides thetaiotaomicron

SAKURAMA Haruko,TSUTSUMI Erika,ASHIDA Hisashi,KATAYAMA Takane,YAMAMOTO Kenji,KUMAGAI Hidehiko
Bioscience, biotechnology, and biochemistry 76(5), 1022-1024, 2012-05-23
Recent studies suggest that α-L-fucosidases of glycoside hydrolase family 29 can be divided into two subfamilies based on substrate specificity and phylogenetic clustering. To explore the validity of …

漢方処方を構成する生薬には様々な配糖体が有効成分として含まれる。配糖体は加水分解されてから吸収され,薬効を発揮する。この加水分解には,腸内細菌が深く関与している。腸内細菌叢の構成は個体差が大きく,配糖体を加水分解する能力を有する腸内細菌の有無が,薬効差を引き起こす一因になることが懸念される。そこで著者らは,人参(Panax ginseng C. A. MEYER)を例にとり,人参配糖体(サポニン) …
