Ensiling legumes such as alfalfa presents challenges because of their high buffer capacity and protein content, as well as their low levels of water-soluble carbohydrates (WSCs), especially for nettle (Zhang et al., 2010). Recently, researchers showed that inoculation with Pediococcus sp. can improve the quality of legume silage by increasing lactic acid (LA) production and reducing pH levels (Kuppusamy et al., 2020). The relative abundance of spherical LAB, such as Pediococcus spp., remains stable in nettle silage (Huang et al., 2023). However, various substances, including condensed tannins and flavonoids, can inhibit Pediococcus sp. activity during ensiling or under specific conditions (Bae et al., 2023). We investigated whether Pediococcus sp. can influence fermentation characteristics or overcome these challenges in nettle silage.
