Abstract

The invention discloses an endophytic fungus strain capable of generating various fatty acids and application of thereof. A strain of aspergillus is provided first, belongs to Aspergillus sp. C1T2-4 and has the preservation number of CCTCC NO:M2019393 in China Center For Type Culture Collection. The invention further provides a fungicide containing the aspergillus and application thereof. The Aspergillus sp. C1T2-4 can generate 15 kinds of fatty acids and has the efficient alpha-linolenic acid synthesis capacity, and 7.15% of alpha-linolenic acid can be separated from the fat produced by the Aspergillus sp. C1T2-4; the Aspergillus sp. C1T2-4 provides an excellent strain material for the development of healthcare products, cosmetics and industrial application in future and has important value.
