The introduction of a forage legume into a tropical pasture should decrease the need for N fertilizer, provided biological N-2 fixation (BNF) contributes enough to compensate for exported N. Macrotyloma axillare (perennial horsegram) is a suitable legume for composing mixed pastures, and our hypothesis is that the isolation of indigenous rhizobia from roots and rhizosphere is the way of achieving an efficient inoculant to maximize BNF to the legume. Nodules and rhizosphere soil taken from M. axillare grown in a mixed pasture with palisade grass were sampled and used in a trap host assay using Leonard jars containing a mixture of vermiculite and sand. A total of ten bacteria were initially isolated using this technique. The isolates were then used in two experiments to evaluate the inoculation responses on the perennial horsegram in greenhouse conditions to which nodulation, plant growth, and shoot N accumulation were measured. Phylogenetic analyses based on 16S rRNA and recA placed all strains within genus Bradyrhizobium, some of them not previously described. The best strain provided more than 120 nodules and more than 65 mg of nodules per plant. Strain BR14182 was considered the most promising given the high dry matter and N accumulation in plant shoots. This study provides the first analysis of Bradyrhizobium diversity nodulating M. axillare in Brazil and provided evidence of the role of inoculation in incrementing the plant-rhizobium symbiosis in a forage legume. |

The influence of two autochthonous lactobacilli strains with probiotic potential (Lactobacillus mucosae CNPC007 and Lactobacillus plantarum CNPC020) in comparison to a commercially available probiotic strain (Lactobacillus rhamnosus LR32) in non-fermented dairy desserts added with ingredients (syrup and hydroethanolic extract) derived from jabuticaba (Myrciaria cauliflora) peels was investigated. L. mucosae showed the best survivability and stability of the studied lactobacilli after processing and during storage, respectively, and also remarkably influenced the texture and sensory features of desserts in comparison to the other strains; L. plantarum achieved viability comparable with the commercial probiotic, above 6 log cfu/g up to the 21st day of the products refrigerated storage. The hydroethanolic extract and syrup from the jabuticaba peel contributed to the phenolic content of the dairy desserts (around 30 mg GAE/100 g) that showed to be able to scavenge DPPH radicals (around 300 g dessert/g DPPH). The different lactobacilli strains did not significantly influence the antioxidant capacity parameters of the desserts (p > 0.05), although the desserts' color was not stable during storage and tended to reduce the acceptability scores of the three trials. Non-fermented dairy desserts with jabuticaba peel ingredients showed to be good sources of phenolic compounds with an antioxidant capacity, offering suitable conditions for the viability maintenance of the autochthonous lactobacilli cultures.
