“…The aNDF, ADF, ADL, and WSC compositions of C. intermedia were significantly lower than that of CK. The Caragana shrub generally contains higher CP, because of nitrogen fixation with rhizobia of legume ( Ji et al, 2015 ). Caragana at the blooming growth stage contained higher WSC and CP contents than the budding growth stage, due to the accumulation of nutrients during growth process ( Xie et al, 2018 ).…”

This study aimed to assess the effects of microbial inoculants and growth stage on fermentation quality, microbial community, and in vitro degradability of Caragana silage from different varieties. Caragana intermedia (CI) and Caragana korshinskii (CK) harvested at the budding (BU) and blooming (BL) stages were used as raw materials to prepare silage, respectively. The silages at each growth stage were treated for ensiling alone (control), with 5% rice bran (RB), a combination of RB with commercial Lactobacillus plantarum (RB + LP), and a combination of RB with a selected strain Lactobacillus plantarum L694 (RB + L694). The results showed that the crude protein (CP) content of CI was higher than that of CK, and delay in harvest resulted in greater CP content in Caragana at BL stage. After 60 days of fermentation, the concentrations of lactic acid (LA) in the RB + L694 treatments were higher than those in control treatments (p < 0.05), while the pH, concentrations of NH3-N, neutral detergent fiber with the addition of α-amylase (aNDF) were lower than those in control treatments (p < 0.05). RB + L694 treatments could decrease acid detergent fiber (ADF) content except in CIBL. In CK silages, adding RB + L694 could reduce bacterial diversity and richness (p < 0.05). Compared with the control, RB + L694 treatment contained higher Lactobacillus and Enterobacter (p < 0.05). In vitro NDF and DM degradability (IVNDFD and IVDMD) was mostly affected by growth period, and additive RB + l694 treatment had higher IVDMD and lower IVNDFD than other treatments (p < 0.05). Consequently, the varieties, growth stages, and additives could influence the fermentation process, while the blooming stage should be selected in both Caragana. Furthermore, the results showed that RB and L. plantarum could exert a positive effect on fermentation quality of Caragana silage by shifting bacterial community composition, and RB + L694 treatments outperformed other additives.

“…Strain CCBAU 65327 T was able to nodulate a wide range of plant species of genera Caragana, Glycyrrhiza, Astragalus, Vigna and Phaseolus (Lu et al, 2009). Isolates 2G-1, 2A-2, 2R-2, 2Y-4 showed a high level of rrs-similarity (99.93-100 %) with the type strain Arthrobacter humicola KV-653 T , isolated from a paddy soil sample in Saitama prefecture in Japan (Kageyama, Morisaki, Ōmura and Takahashi, 2008), while the isolate 2Y-1 was identified as Kocuria rosea (100 % rrs-similarity with the type strain DSM 20447 T ) (Stackebrandt, Koch, Gvozdiak and Schumann, 1995).…”

Twenty-nine strains were isolated from two samples of the permafrost active layer of the Spitsbergen archipelago. The estimated number of bacteria ranged from 4.0⋅104 to 1.7⋅107 CFU∙g-1. As a result of sequencing of the 16S rRNA (rrs) genes, the isolates were assigned to 13 genera belonging to the phyla Actinobacteria, Proteobacteria (classes α, β, and γ), Bacteroidetes, and Firmicutes. Six isolates belonged to the rhizobial genus Mesorhizobium (order Rhizobiales). A plant nodulation assay with seedlings of legume plants Astragalus norvegicus, A. frigidus, A. subpolaris and Oxytropis sordida, originated from Khibiny (Murmansk region, Russia) and inoculated with Mesorhizobium isolates, showed the inability of these strains to form nodules on plant roots. Symbiotic (sym) genes nodC and nodD were not detected in Mesorhizobium strains either.
