Abstract: A microbial strain of Lachnospiraceae is a species of a genus of the family Lachnospiraceae (Lachnospiraceae sp.). The nucleotide sequence of 16S rRNA of the microbial strain of Lachnospiraceae is as shown in SEQ ID No. 1. The intestinal anaerobic microbial strain Lachnospiraceae sp. can inhibit the growth rate of tumors and can be used for preventing and/or treating tumors. The tumors include at least one of liver cancer, colon cancer, rectal cancer, colorectal cancer, lung cancer, breast cancer, cervical cancer, ovarian cancer, pancreatic cancer, cholangiocarcinoma, kidney cancer, and fibrosarcoma.
