    2023年6月9日，據(jù)歐盟食品安全局（EFSA）消息，應(yīng)歐盟委員會(huì)要求，歐盟動(dòng)物飼料添加劑和產(chǎn)品（FEEDAP）研究小組就一種由內(nèi)切-1,4-β-木聚糖酶（endo-1,4-β-xylanase）、內(nèi)切-1,3（4）-β-葡聚糖酶（endo-1,3(4)-beta-glucanase）和內(nèi)切-1,4-β-葡聚糖酶（endo-1,4-beta-glucanase）組成的飼料添加劑對(duì)育肥家禽、產(chǎn)蛋家禽和斷奶仔豬的安全性和有效性發(fā)表科學(xué)意見。

據(jù)了解，添加劑中的三種酶是由里氏木霉ATCC 74444生產(chǎn)的。部分原文報(bào)道如下：

Ronozyme?Multigrain G/L is the trade name of the feed additive under assessment containing endo-1,4-beta-xylanase, endo-1,4-beta-glucanase and endo-1,3(4)-beta-glucanase produced by a non-genetically modified strain of Trichoderma reesei (ATCC 74444). It is authorised for use as a zootechnical additive (functional group: digestibility enhancer) in poultry for fattening, poultry for laying and weaned piglets. This scientific opinion concerns the request for the renewal of the authorisation of the additive for the species/categories for which there is an authorisation. The applicant provided evidence that the additive currently in the market complies with the conditions of the authorisation. There is no new evidence that would lead the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) to reconsider previous conclusions that the additive is safe for the animal species/categories, the consumer and the environment under the authorised conditions of use. Regarding the safety for the user, the additive should be considered a potential respiratory sensitiser. In absence of data, the Panel could not conclude on the potential of the additive to cause skin and eye irritation or dermal sensitisation. There was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation for poultry for fattening, poultry for laying and weaned piglets.
