“…Members of the genus Bifidobacterium are purported to have beneficial consequences for human health (Backhed, Ley, Sonnenburg, Peterson, & Gordon, ; Guarner & Malagelada, ; Nowak, Paliwoda, & Blasiak, ; Tojo et al, ). Currently, GenBank Taxonomy recognizes 71 species of Bifidobacterium that have been isolated from the gastrointestinal tracts of mammals, birds and social insects as well as human‐impacted environments (Bottacini, Ventura, van Sinderen, & O'Connell Motherway, ; Killer et al, ; Michelini, Modesto et al, ; Milani et al, ). Bifidobacteria are noted for their ability to degrade ingested polysaccharides and proteins, and to synthesize vitamins and other nutrients that are beneficial to their hosts (Coakley et al, ; Kiyohara et al, ; Lugli et al, ; Milani et al, ; Milani, Lugli et al, ; O'Connell Motherway, Kinsella, Fitzgerald, & van Sinderen, ; Pompei et al, ).…”

The genus Bifidobacterium is purported to have beneficial consequences for human health and is a major component of many gastrointestinal probiotics. Although species of Bifidobacterium are generally at low relative frequency in the adult human gastrointestinal tract, they can constitute high proportions of the gastrointestinal communities of adult marmosets. To identify genes that might be important for the maintenance of Bifidobacterium in adult marmosets, ten strains of Bifidobacterium were isolated from the feces of seven adult marmosets, and their genomes were sequenced. There were six B. reuteri strains, two B. callitrichos strains, one B. myosotis sp. nov. and one B. tissieri sp. nov. among our isolates. Phylogenetic analysis showed that three of the four species we isolated were most closely related to B. bifidum, B. breve and B. longum, which are species found in high abundance in human infants. There were 1357 genes that were shared by at least one strain of B. reuteri, B. callitrichos, B. breve, and B. longum, and 987 genes that were found in all strains of the four species. There were 106 genes found in B. reuteri and B. callitrichos but not in human bifidobacteria, and several of these genes were involved in nutrient uptake. These pathways for nutrient uptake appeared to be specific to Bifidobacterium from New World monkeys. Additionally, the distribution of Bifidobacterium in fecal samples from captive adult marmosets constituted as much as 80% of the gut microbiome, although this was variable between individuals and colonies. We suggest that nutrient transporters may be important for the maintenance of Bifidobacterium during adulthood in marmosets.

One or wherever possible two representative strains for each group were selected and a total of eight strains were chosen (RST 8 and RST 16 T for Group I, RST 9 T for Group II, RST 7 and RST 11 for Group III, RST 19 for Group IV, RST 17 for Group V and RST 27 for Group VI) for 16S rRNA gene sequencing as described by Michelini et al [16].…”

“…On the basis of the phenotypic and chemotaxonomic characterization as well as the molecular-based methods phylogenetic analysis based on the 16S rRNA gene sequences, MLSA based on the concatenated five housekeeping gene sequences, and the wholegenome-based sequence comparisons in silico, strains RST 16 T and RST 9 T were genetically and phenotypically discernible from the currently recognized species of bifidobacteria; thus, according to Minimal Standard guidelines [16], they represent two novel taxa for which the name Bifidobacterium vespertilionis sp. nov. and Bifidobacterium rousetti sp.…”

“…The strains used in this study, Bifidobacterium aesculapii MRM3/1 and MRM4/2, Bifidobacterium aerophilum TRE26 and Bifidobacterium avesanii TREC, are new bifidobacteria species isolated from primates that have been characterized from a morphological, biochemical and molecular point of view (Modesto et al ; Michelini et al ), while B. animalis subsp . lactis P32/1 was isolated from chicken faeces (Mattarelli et al ).…”

“…These limitations have led to the collection of new Bifidobacterium strains correctly identified and characterized, with not only functional but also technological properties, for the development of new probiotics with the potential to be successfully incorporated into a food product (Pandey et al 2015). Numerous studies refer to bifidobacteria isolated from humans; in contrast, those relating to bifidobacteria from nonhuman sources are scarce (Ushida et al 2010;Endo et al 2012;D'Aimmo et al 2014;Modesto et al 2014;Tsuchida et al 2014;Michelini et al 2015Michelini et al , 2016.…”

Novel bifidobacteria strains isolated from nonconventional sources. Technological, antimicrobial and biological characterization for their use as probiotics

Aim To characterize four novel autochthonous bifidobacteria isolated from monkey faeces and a Bifidobacterium lactis strain isolated from chicken faeces by evaluating their technological and biological/functional potential to be used as probiotics. Different stressors, including food process parameters and storage, can affect their viability and functionality. Methods and Results The resistance to frozen storage, tolerance to lyophilization and viability during storage, thermal, acidic and simulated gastric resistance, surface hydrophobicity and antimicrobial activity against pathogens were studied. Bifidobacterium lactis Bb12 and INL1 were used as reference strains. The results obtained demonstrated that the new isolates presented strain‐dependent behaviour. Good results were obtained for thermal resistance, frozen storage at −80°C and lyophilized powders maintained at 5°C. Cell viability during refrigerated storage was higher when the strains were resuspended in milk at pH 5·0 than at 4·5. The surface hydrophobicity ranged between 7 and 98% depending on the strain. The simulated gastric resistance was improved for the strains incorporated in cheese. Regarding antimicrobial activity, bifidobacteria isolated from monkey presented higher inhibitory capacity than the reference strains. Conclusion This research provides a deeper insight into new strains of bifidobacteria isolated from primates and chicken that have not been previously characterized for their potential use in dairy products and confirm the most robust stress tolerance of B. lactis. Significance and Impact of the Study The possibility of expanding the available bifidobacteria with the potential to be added to a probiotic food necessarily implies characterizing them from different points of view, especially when considering unknown species. For monkey isolates (which showed higher antimicrobial activity against pathogens), more in‐depth knowledge is needed before applying strategies to improve their performance. On the contrary, the chicken isolate B. lactis P32/1 showed similar behaviour to the references B. lactis strains; therefore, it could be considered as a potential probiotic candidate.
