(ORDO NEWS) — Scientists from the Guangzhou Institute of Microbiology found that bacteria that secrete antioxidant substances are common in the intestines of Chinese centenarians.
The scientists analyzed the composition of the gut microbiomes of 247 healthy people from the city of Jiaoling, sometimes called the “city of centenarians.”
Among the project participants, 18 were over 100 and 19 were between 81 and 99 years of age.
Biologists identified bacteria from 107 families in participants’ stool samples. In people older than 80 years, the number of bacteria from the genera Lactobacillus, Akkermansia, Methanobrevibacter, Roseburia was increased.
The scientists also characterized the most active genes of intestinal bacteria, primarily those associated with the production of antioxidant substances.
They found that intragastric administration of the most “antioxidant” strain of Lactobacillus plantarum 124 in animals reduced signs of oxidative stress in the liver and kidneys.
The scientists’ results indicate that the gut microbiota may play an important role in life extension, but this hypothesis requires further research.
