“…All three genomes contain predicted l -arabinose isomerase genes (COO72_RS01355, CPA40_RS10585, BCAL_RS05330), which could convert arabinose to ribulose and galactose to tagatose. The presence of genes associated with galactose and arabinose metabolism is consistent with the major carbon constituents of tree gums found in common marmoset habitats [ 34 ]. α,α-phosphotrehalase (COO72_RS08005, CPA40_RS06370, BCAL_RS06195), which converts trehalose 6-phosphate to d -glucose 6-phosphate, may reflect the marmoset's utilization of alternative nutritive sources in addition to gums.…”

The comparative genomics of Bifidobacterium callitrichos reflects dietary carbohydrate utilization within the common marmoset gut

Bifidobacterium is a diverse genus of anaerobic, saccharolytic bacteria that colonize many animals, notably humans and other mammals. The presence of these bacteria in the gastrointestinal tract represents a potential coevolution between the gut microbiome and its mammalian host mediated by diet. To study the relationship between bifidobacterial gut symbionts and host nutrition, we analyzed the genome of two bifidobacteria strains isolated from the feces of a common marmoset (Callithrix jacchus), a primate species studied for its ability to subsist on host-indigestible carbohydrates. Whole genome sequencing identified these isolates as unique strains of Bifidobacterium callitrichos. All three strains, including these isolates and the previously described type strain, contain genes that may enable utilization of marmoset dietary substrates. These include genes predicted to contribute to galactose, arabinose, and trehalose metabolic pathways. In addition, significant genomic differences between strains suggest that bifidobacteria possess distinct roles in carbohydrate metabolism within the same host. Thus, bifidobacteria utilize dietary components specific to their host, both humans and non-human primates alike. Comparative genomics suggests conservation of possible coevolutionary relationships within the primate clade.

“…The common marmoset is one of 27 mammalian species considered to be obligate exudivores [ 33 ]. The exudatory diet of common marmosets provides a rich source of plant β-linked polysaccharides, consisting largely of galactose, arabinose, and rhamnose [ 34–37 ].…”

A goma do angico foi purificada através de três estágios, cada um deles envolvendo dissolução em água e precipitação em etanol. As duas primeiras precipitações foram efetuadas em presença de NaCl e a última, em ausência. Os teores de umidade, cinza, proteína e cátions foram determinados para a goma nos vários estágios de purificação. A composição do polissacarídeo, obtida por HPLC, foi: 67,8% de arabinose, 24,1% de galactose e 2,0% de ramnose. O teor de 5,9% de ácido urônico foi calculado a partir de titulação condutométrica. Os cátions presentes na goma bruta (Na+, K+, Ca2+, Mg2+ e Fe3+) foram analisados por absorção atômica e gradualmente substituídos por Na+. O teor de proteína, no entanto, não diminuiu significativamente ao longo das purificações, o que pode ser um indicativo de que ela se encontra agregada ao polissacarídeo. O estudo por GPC sugere a presença de um complexo polissacarídeo-proteina de massa molar 7,9 x 10(5) g/mol e de polissacarídeos de massa molar 8,3 x 10(4) g/mol e 2,2 x 10(4) g/mol. A goma do angico apresenta baixa viscosidade e Energia de ativação de fluxo 16,8 kJ/mol, 17,2 kJ/mol e 17,7 kJ/mol, respectivamente para soluções 2%, 3% e 5%. Comparação com outros polissacarídeos indica que a macromolécula é ramificada, mas em menor grau do que a goma arábica e a goma do cajueiro.

“…Further study of this question would help us understand the marmosets selection and exploitation of exudate resources. It is known that the exudates of Anadenanthera have high concentrations of polysaccharides and calcium [50] , [51] and exudate polysaccharides are an important energy source for marmosets [52] . Calcium plays an important role to maintain the calcium/phosphorus metabolism balance of organisms [53] .…”

Vegetable Exudates as Food for Callithrix spp. (Callitrichidae): Exploratory Patterns

et al. 2014

Marmosets of the genus Callithrix are specialized in the consumption of tree exudates to obtain essential nutritional resource by boring holes into bark with teeth. However, marmoset preferences for particular tree species, location, type, and other suitable factors that aid in exudate acquisition need further research. In the current study, the intensity of exudate use from Anadenanthera peregrina var. peregrina trees by hybrid marmosets Callithrix spp. groups was studied in five forest fragments in Viçosa, in the state of Minas, Brazil. Thirty-nine A. peregrina var. peregrina trees were examined and 8,765 active and non-active holes were analyzed. The trunk of A. peregrina var. peregrina had a lower number of holes than the canopy: 11% were found on the trunk and 89% were found on the canopy. The upper canopy was the preferred area by Callithrix spp. for obtaining exudates. The intensity of tree exploitation by marmosets showed a moderate-to-weak correlation with diameter at breast height (DBH) and total tree height. The overall results indicate that Anadenanthera peregrina var. peregrina provides food resources for hybrid marmosets (Callithrix spp.) and these animals prefer to explore this resource on the apical parts of the plant, where the thickness, location, and age of the branches are the main features involved in the acquisition of exudates.
