  • Aureobasidium pullulans strains with high-yield heavy oil and construction method and application thereof
    Patent number: 11352633
    Abstract: An Aureobasidium pullulans recombinant strain with high-yield heavy oil and a construction method and application thereof are provided. The Aureobasidium pullulans recombinant strain is obtained by knocking out a pullulan synthetase PUL gene while overexpressing an ACL gene. The obtained Aureobasidium pullulans recombinant strain can significantly increase the yield of heavy oil. After 7-day fermentation with xylose as carbon source, the yield of the heavy oil of the recombinant strain reaches 19.4372 g/L, while the yield of the heavy oil of the original strain is 10.0325 g/L, i.e. the recombinant strain improves the yield by 93.74% compared with the original strain.
