A yeast extract with high base and base derivative contents and a method for preparing same. The yeast extract with high base and base derivative contents provided herein comprises 20000-40000 mg/kg of bases and base derivatives. The yeast extract provided herein is rich in bases and base derivatives that can be more easily absorbed by microorganisms than nucleotides, thus having a high effect on promoting microbial growth.

A method is for stimulating the growth of bacteria of the Bacteroidetes phylum in the gut microbiota of a mammal. The method includes administering a yeast product as a prebiotic agent to the mammal. The yeast product comprises the walls of yeast cells, such as those of the genera Saccharomyces, Pichia, Candida, Kluyveromyces, Yarrowia and/or Wickehomomyces, or a fraction thereof.
