    2023年2月21日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就二醇脱水酶（Lentilactobacillus diolivorans） DSM 33625作为所有动物青贮饲料添加剂的安全性和有效性发表科学意见。

经过评估，专家小组认为在拟议的使用条件下，该添加剂对目标物种、消费者和环境是安全的。该添加剂以最小浓度1×10⁸CFU/kg饲料的水平下可以延长从容易和中度困难青贮饲料材料(DM范围为32-65%)制备青贮饲料的有氧稳定性。部分原文报道如下：

Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on Lentilactobacillus diolivorans (formerly Lactobacillus diolivorans) DSM 33625 when used as a technological additive to improve ensiling of forage. The additive is intended for use with all forages and for all animal species at a proposed minimum concentration of 1 × 10⁸colony forming units (CFU)/kg forage. The bacterial species L. diolivorans is considered by EFSA to be suitable for the qualified presumption of safety approach to safety assessment. As the identity of the strain has been clearly established and no acquired antimicrobial resistance determinants of concern were detected, the use of the strain as a silage additive is considered safe for livestock species, for consumers of products from animals fed the treated silage and for the environment. The additive is not a skin or an eye irritant. In the absence of data, no conclusion can be drawn on the skin sensitisation of the additive. Given the proteinaceous nature of the active agent, the additive should be considered a respiratory sensitiser. The FEEDAP Panel concluded that Lentilactobacillus diolivorans DSM 33625 at a minimum concentration of 1 × 10⁸CFU/kg forage may extend the aerobic stability of silage prepared from easy and moderately difficult to ensile forage material with a DM range of 32–65%.
