　　据了解，这种��-甘露聚糖酶由Paenibacillus lentus DSM 33618产生。经过评估，专家小组认为在建议的使用条件下该添加剂对目标物种、消费者和环境是安全的。该添加剂在32�?00 U/kg饲料水平下对育肥鸡、饲养用于产蛋的鸡、饲养用于产蛋的小型家禽物种、育肥猪和小型猪种是有效的，�?8�?00 U/kg饲料水平下对育肥火鸡、饲养用于繁殖的火鸡和断奶仔猪有效。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 endo-1,4-��-d-mannanase (Hemicell ?HT/HT-L) produced by a genetically-modified strain of Paenibacillus lentus (DSM 33618) as a zootechnical feed additive for chickens and turkeys for fattening, chickens reared for laying, turkeys reared for breeding, minor poultry species to point of lay, pigs for fattening, piglets (weaned) and minor porcine species. The production strain was obtained from a Paenibacillus lentus recipient strain that has been e valuated previously by EFSA and co nsidered to be safe. The genetic modification does not raise safety co ncerns and there were no antibiotic resistance genes from the genetic modification in the production strain. Viable cells and the DNA of the production strain were not found in the intermediate product used to formulate the additive. Hemicell ?HT/HT-L produced by Paenibacillus lentus DSM 33618 is co nsidered safe for the above-mentio ned target species at the intended co nditions of use. The use of Hemicell ?HT/HT-L as a feed additive raises no co ncerns for the co nsumer or for the environment. Hemicell ?HT/HT-L is not irritant to the skin and eyes but is regarded as a dermal sensitiser and a potential respiratory sensitiser. The additive has a potential to be efficacious at 32,000 U/kg in chickens for fattening, chickens reared for laying, minor poultry species for fattening or reared for laying/breeding, pigs for fattening and minor porcine species, and at 48,000 U/kg in turkeys for fattening, turkeys reared for breeding and weaned piglets.
