摘要： Provided are a Candida tropicalis strain Am2525, with the preservation number thereof being CCTCC NO: M 2019419, and a method for producing long-chain dicarboxylic acids by means of fermenting the strain. The method for producing the long-chain dicarboxylic acids comprises preparing a seed solution by means of the Candida tropicalis strain Am2525 and producing the long-chain dicarboxylic acids via fermentation of the seed solution. Compared with the parent, the Candida tropicalis strain Am2525 has an enhanced resistance to the toxicity of a substrate decane, improves the productivity of long-chain dicarboxylic acids, reduces the cost of production, subsequent separation and purification are simple, and the fermentation production process is easy to implement on a large scale.
