The present disclosure discloses a method for removing TBBPA in water, a microbial strain and a microbial agent, wherein the microbial strain is a domesticated Burkholderia cepacia strain, which is named Y17 with a conservation number GDMCC No. 62153. The microbial agent and the method for removing TBBPA in water with the microbial agent are that Y17 strains are colonized on the surface and pore channels of biochar, TBBPA in water is used as a carbon source, air and dissolved oxygen are used as oxygen sources, biochar provides the strains a growth microenvironment for degrading TBBPA in water, the strains are subjected to aerobic growth in water, and bio-enhanced degradation of TBBPA in water is performed by continuously degradation reaction. The removal method and the microbial strain as well as the microbial agent are high in degradation efficiency, environmental-friendly and low in cost, and can meet requirements on large-range promotion and application.

Provided are an Anaerostipes sp. B2131 strain and an application thereof in inflammatory bowel diseases. The Anaerostipes sp. B2131 strain has a deposit number of CGMCC NO. 1.5.5295. The Anaerostipes sp. B2131 strain is used for regulating the homeostasis of intestinal flora, and preventing and treating the occurrence of an intestinal disease such as an inflammatory bowel disease.
