經過評估，專家小組認為在擬議的使用條件下，該添加劑對目標物種、消費者和環境是安全的。該添加劑以最小濃度1×10⁸CFU/kg飼料的水平下可以延長從容易和中度困難青貯飼料材料(DM范圍為32-65%)制備青貯飼料的有氧穩定性。部分原文報道如下：

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%.
