例如,已知Ruminococcus bromii对健康具有有益效果。 当长期食用水果和蔬菜时,瘤胃球菌属能够发酵复合糖类,产生乙酸酯、丙酸盐以及具有抗炎效益的丁酸盐。 肉食增加有害菌 Ruminococcus gnavus 部分瘤胃球菌属已被证明具有促炎性。以动物为基础的饮食会增加有害菌Ruminococcus gnavus,减少参与食物中植物多糖代谢的有益菌...
肥胖(超重):一项研究包括肥胖组(BMI≥40kg/m2)和对照组(BMI在18.5 ~ 24.9kg/m2之间)的粪便菌群,其中Ruminococcus bromii, Ruminococcus obeum 在肥胖患者中丰度较高。 非酒精性脂肪肝:与单纯性脂肪肝患者相比,非酒精性脂肪性肝炎患者瘤胃球菌属丰度升高。 肝细胞癌:肝细胞癌患者粪便中瘤胃球菌(Ruminococcus)、肠球菌...
自闭症:在患有便秘和腹泻的自闭症谱系障碍儿童的粪便中Ruminococcus torques和Ruminococcus gnavus的丰度增加。 肥胖(超重):一项研究包括肥胖组(BMI≥40kg/m2)和对照组(BMI在18.5 ~ 24.9kg/m2之间)的粪便菌群,其中Ruminococcus bromii, Ruminococcus obeum 在肥胖患者中丰度较高。 非酒精性脂肪肝:与单纯性脂肪肝患者相...
3.2 Ruminococcus bromii R. bromii is a core gut microbiota species found in humans and animals (Umu et al., 2015). It encodes a narrow spectrum of carbohydrate-active enzymes (CAZymes), which play a crucial role in the degradation of dietary resistant starch (Ze et al., 2013) to produce...
fibers. For example, Ruminococcus flavefaciens, which is commonly found in cattle, goats and sheep, is particularly good at degrading cellulose (the main component of plant cell walls). In the human gut, Ruminococcus bromii is the species of bacterium that acts as this specialist starch de...
The human gut symbiont Ruminococcus bromii expresses Sas6 (Starch Adherence System member 6), which consists of two starch-specific carbohydrate-binding modules from family 26 (RbCBM26) and family 74 (RbCBM74). Here, we present the crystal structures of Sas6 and of RbCBM74 bound with a ...
For example, Ruminococcus champanellensis is the most active cellulolytic bacterium isolated from the human colon [10], whilst Ruminococcus bromii has a key role in the fermentation of resistant starch [11]. Fermentation of these complex polysaccharides results in the production of short chain fatty...
2012. Ruminococcus bromii is a keystone species for the degradation of resistant starch in the human colon. ISME J 6:1535-1543. https://doi.org/10.1038/ismej.2012.4.Ze X, Duncan SH, Louis P, Flint HJ. Ruminococcus bromii is a key- stone species for the degradation of resistant starch ...
