據(jù)了解，這種食品酶是由非轉(zhuǎn)基因副地衣芽孢桿菌菌株LMG S-30155生產(chǎn)的，旨在用于油類生產(chǎn)、植物/微生物/動物蛋白的水解、酵母加工和調(diào)味制劑的生產(chǎn)。

經(jīng)過評估，專家小組認為，由非轉(zhuǎn)基因副地衣芽孢桿菌菌株LMG S-30155生產(chǎn)的食品酶枯草桿菌蛋白酶不能被認為是安全的。部分原文報道如下：

The food enzyme subtilisin (serine endopeptidase, EC 3.4.21.62) is produced with the non-genetically modified microorganism Bacillus paralicheniformis strain LMG S-30155 by ENMEX SA de CV, now part of Kerry Food Ingredients (Cork) Ltd. The food enzyme is intended to be used in oil production, hydrolysis of vegetable/microbial/animal proteins, yeast processing and production of flavouring preparations. The production strain of the food enzyme contains known antimicrobial resistance genes and genes involved in bacitracin biosynthesis. Consequently, it does not fulfil the requirements for the QPS approach to safety assessment. Bacitracin was detected in the food enzyme and the ■■■■■ The presence of bacitracin, a medically important antimicrobial, in the food enzyme represents a risk for the development of resistance in bacteria. Due to the presence of bacitracin, the Panel concluded that the food enzyme subtilisin produced with the non-genetically modified Bacillus paralicheniformis strain LMG S-30155 cannot be considered safe.
