Ester-producing yeast DebaryomyceshanseniiH32 and application thereof

The invention relates to a strain of ester-producing yeast DebaryomyceshanseniiH32 and an application thereof. The strain is preserved in the Guangdong Microbial Culture Collection Center on June 10, 2021, the preservation address is the 5th floor, No.59 building, No.100 Courtyard, Xianlie Middle Road, Guangzhou City, Guangdong Province, and the preservation number is GDMCCNO:61716. A yeast strain is separated from Chinese chestnuts, the strain is a high-temperature-resistant yeast strain, the highest tolerable temperature is 50 DEG C, the strain can tolerate 20 g/L of lactic acid, meanwhile, the strain has good ethanol tolerance, and the highest tolerable volume fraction is 8%; under the optimal fermentation condition, the ester yield can reach 1.17 g/L, and high ester yield is achieved. 本发明涉及一株产酯酵母DebaryomyceshanseniiH32及其应用。该菌株于2021年6月10日保藏于广东省微生物菌种保藏中心，保藏地址为广东省广州市越秀区先烈中路100号大院59号楼5楼，保藏号为GDMCCNO:61716。本发明从板栗中分离得到一株酵母菌，该菌株是一株耐高温酵母，最高耐受温度为50℃，且能耐受20g/L乳酸，同时具有较好的乙醇耐受性，最高耐受体积分数为8％；其最优发酵条件下产酯量可达1.17g/L，具有高产酯的性能
