The invention discloses a novel
Bifidobacterium strain, namely IMAU50987, and belongs to the technical field of bifidobacteria. The invention further discloses a preparation method of the novel Bifidobacteria strain, namely IMAU50987. The invention provides a novel
bifidobacterium strain IMAU50987, the 16S rRNA sequence of the strain is as shown in SEQ ID NO.1, and the strain is separated from
cliff black
honeycomb honey in Dai nationality, Jingyan nationality, Autonomous Dai nationality, Liangghe County, Dehong, Yunnan Province. The strain is preserved in Guangdong Microbial Culture Collection Center on August 8th, 2024, the address is the 5th floor of the Experimental Building, No.100 Court, Middle Xianlie Road, Guangzhou City, Guangdong Province, and the preservation number is GDMCC No: 64993, and the strain is preserved in Japan Microbial Culture Collection Center on October 3th, 2023, the address is Institute of Physical and
Chemical Research, Tsubao City, Japan Shuzhou County, and the preservation number is JCM 36315. The novel
bifidobacterium strain IMAU50987 grows well on an mMRS
agar culture medium, the
optimum growth temperature is 35 DEG C, the optimum pH is 6, the
bacterial colony is round, semitransparent and convex after being cultured for 72 hours, and the
diameter is about 1 mm; two
drug-
resistant genes and two
virulence genes are retrieved in the
genome,
hemolysis is avoided, and the
gene is sensitive to various
antibiotics.
