Acid-resistant Jubrubergi Lindnella yeast and application thereof

The invention discloses an acid-resistant Jubrueckia jadinii C-12-2 strain and an application thereof, and belongs to the technical field of microorganisms, the acid-resistant Jubrueckia jadinii is Cyberlindnera jadinii C-12-2 and is preserved in Guangdong Microbial Culture Collection Center on March 5, 2024, and the preservation number is GDMCC NO: 64388. The acid-resistant Jubrueckia jadinii has the advantages that the acid-resistant Jubrueckia jadinii can be used for preparing acid-resistant Jubrueckia jadinii; the lindnella gedinieri provided by the invention can grow in a culture medium with the pH value of 3.5, and the crude protein content can reach 70.02% after 24 hours of fermentation. The lindnella gedinieri provided by the invention is a strain obtained through heavy ion irradiation mutagenesis and acid-resistant domestication, the strain can grow in an acid culture medium with the pH value of 3.5 through determination, the obstacle that an original strain cannot grow at a low pH value is overcome,
