Blautia spp. as Next Generation Probiotics

Background Blautia spp. and Diseases Products FAQs Resources

Introduction of Blautia spp.

Creative Biolabs dedicates itself from the first day to developing live biotherapeutic products (LBP), backed by decades of experience. Our custom LBP service covers the entire process. With our experience and technology, we can find solutions for your projects.

Introduction of Blautia spp.

Blautia species are strictly anaerobic, nonmotile, usually spherical or oval, appear in pairs or chains, 1.0-1.5×1.0-3.0 μm in size, and most strains are sporeless. The optimum temperature and pH for most Blautia strains are 37℃ and 7.0, respectively. The GC content of Blautia DNA is 37-47 mol%. The ability of Blautia to produce bacteriocins has the potential to inhibit the colonization of pathogenic bacteria in the intestinal tract and can affect the composition of intestinal flora, making it a potential probiotic and possible to play the function of probiotics. The following three species have been studied extensively:

Blautia producta is a novel probiotic to exert a prominent antihyperlipidemic effect. Also, it may be a new therapeutic developed for inflammatory bowel disease and other inflammatory disorders.

Blautia wexlerae is a major acetate producer. The animal experiment has shown that butyrate can improve insulin resistance and reduce fat accumulation. Therefore, this may be one of the mechanisms of Blautia wexlerae anti-obesity. It has potential for development in the treatment of metabolic diseases.

Blautia faecis could be developed as a therapeutic drug, either through its supernatant, isolated bioactive compounds, or as an LBP.

Relationships Between Blautia spp. and Host Health

Blautia, is a dominant genus in the intestinal flora and is significantly associated with host physiological disorders, such as obesity, diabetes, cancer, and various inflammatory diseases.

Diseases Functions of Blautia spp.
The Obesity-related Diseases One study observed a change in the composition of intestinal microbiota and an increase in the abundance of Blautia in overweight/obese patients with nonalcoholic fatty liver who consumed a low-calorie and high-protein diet for 3 weeks. Blautia was a dominant genus in the intestinal flora of women in the effective weight loss group, but not in the ineffective weight loss group. In another study, the abundance of Blautia decreased significantly in children with diabetes compared with healthy children. A cross-sectional study suggested that Blautia, specifically B. luti and B. wexlerae, may help reduce inflammation associated with obesity-related complications.
Inflammatory Diseases Blautia, as a genus of commensal obligate anaerobic bacteria, plays an important role in maintaining the ecological balance in the intestine and preventing inflammation by upregulating intestinal regulatory T cells and producing SCFAs. Analysis of fecal and mucosal microflora in IBD patients and healthy people showed that the abundance of Blautia was significantly reduced in cecal mucosal microflora in CD patients. Similarly reduced abundance of Blautia has been reported in mucosal adhesion flora of colorectal cancer patients. Despite the lack of clarity on the potential mechanism of Blautia in various diseases, Blautia abundance can still be used as a potential tool for the early diagnosis or treatment of related diseases.

What therapeutic potentials do Blautia spp. offer?

Blautia species are known for their beneficial impacts on human health, particularly through the production of bacteriocins which can inhibit pathogenic bacteria. Specific strains like Blautia producta and Blautia wexlerae have been studied for their roles in managing metabolic disorders such as hyperlipidemia, obesity, and type 2 diabetes mellitus. Blautia faecis has also shown promise in respiratory infection models.

How are Blautia spp. strains developed and characterized for therapeutic use?

Companies like Creative Biolabs utilize advanced microbial screening and isolation techniques to develop and characterize Blautia strains. This includes evaluating their bioactive compounds and potential as live biotherapeutic products, ensuring safety and efficacy for therapeutic uses.

What future research directions are being explored with Blautia spp. in the context of NGPs?

Current research is focused on expanding the understanding of Blautia spp.'s mechanisms of action, particularly how they modulate the gut microbiota and immune responses. Future studies are likely to delve deeper into personalized probiotic therapies, targeted delivery mechanisms, and their roles in broader health outcomes.

How does Creative Biolabs ensure the quality and efficacy of Blautia spp. strains?

Creative Biolabs implements rigorous microbial identification and biological safety tests to ensure the quality and efficacy of Blautia spp. strains. Their comprehensive platform supports everything from strain isolation to small-scale production, ensuring that each probiotic product meets the highest standards of research and therapeutic potential.
