　　据了解，该添加剂是由里氏木霉CBS 140027生产的。部分原文报道如下：

　　Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of ECONASE? XT (endo�?,4�?beta;‐xylanase) produced by a genetically modified strain of Trichoderma reesei (CBS 140027) as a zootechnical feed additive for piglets (weaned), pigs for fattening, chickens for fattening, chickens reared for laying, laying hens, turkeys for fattening, turkeys reared for breeding and minor poultry species. The recipient strain and the production strain T. reesei CBS 140027 are co nsidered safe. The additive is safe for chickens for fattening and weaned piglets at the maximum recommended doses (16,000 and 24,000 BXU/kg feed, respectively) with a wide margin of safety (100‐fold and 50‐fold, respectively). These co nclusions are extended to chickens reared for laying and to pigs for fattening at 16,000 and 24,000 BXU/kg feed, respectively. The additive is safe for turkeys for fattening or reared for breeding at 16,000 BXU/kg feed. The FEEDAP Panel cannot co nclude on the safety of the additive for laying hens and for minor poultry species for laying at the proposed co nditions of use. The information provided does not allow to co nclude on the safety of the use of ECo nASE XT? P/L produced by T. reesei CBS 140027 in animal nutrition for the consumers. The use of the additive under assessment in animal nutrition does not raise safety co ncerns for the environment. ECONASE? XT L is non‐irritant to the skin or to the eyes. In absence of data, the FEEDAP Panel cannot co nclude on the potential of the solid product to be irritant to skin and eyes and on the potential of the additive in all forms to be a dermal sensitiser. All forms of the additive should be co nsidered as respiratory sensitisers. All forms of the additive are co nsidered efficacious at the minimum recommended levels for the target species.
