Problems solved by technology

Moreover, the demand for long-chain dibasic acids is increasing year by year, which cannot meet the needs of the future market
[0005] At present, the domestic industrialization of producing long carbon chain dibasic acids by using alkanes as substrate fermentation method has been realized, but the production technology and equipment are backward, small scale, high energy consumption, high production cost, few varieties of products The grade is low, and only C11 to C14 dibasic acids can be produced, and the serial production of long-chain dibasic acids has not been formed, which limits the application fields of downstream products of long-chain dibasic acids and cannot satisfy the market need
