Strains LTG7, I5, and G could ferment rhamnose while strains LCG3 and LI3 could not.
The phylogenetic tree of partial 16S rDNA sequences of LCG3, LTG7, I5, and LI3 is presented in Figure 1.
At 25[degrees]C, compared to G, LI3 showed the similar pH (p<0.
At 25[degrees]C, LI3 and LTG7 had higher LAB counts than G (p<0.
Consequently, strains LCG3, LTG7, I5, and LI3 could be identified as Lactobacillus plantarum, Pediococcus acidilactici, Lactobacillus paraplantarum, and Lactobacillus casei, respectively.
Among the five inoculants, only strain I5 and LI3 showed a high and consistent ability to produce acids even at 10[degrees]C, as indicated by the medium pH after inoculation.
The silage inoculated with G had a higher ratio of LA/AA than the silages with isolated LAB strains at 25[degrees]C, whereas the silages inoculated with LTG7, I5, and LI3 at 10[degrees]C and 15[degrees]C had higher ratios of LA/AA than the silages inoculated with G.
