Meta.olic cha.a.teriza.ion of selected probiotic consortia.during gluten a.d whea. brea. simula.ed digestion

While exerting their meta.olic a.tivities in the ga.trointestina. milieu， probiotics impa.t the host well-being by boosting immunity， trea.ing meta.olic disorders， a.d modula.ing microbiota.a.d meta.olome. Due to the high incidence of gluten-ba.ed disorders， the present work a.ms to deeply explore the meta.olism of two selected microbia. consortia.(MCs) during gluten digestion under simula.ed ga.trointestina. conditions. Fea.ured by high protea.e a.d peptida.e a.tivity， both MCs a.counted for different la.tic a.id ba.teria.a.d Ba.illus stra.ns tha. were combined with two commercia. protea.e enzymes. Gluten substra.es were used a. purified extra.ts， white a.d whole whea. brea.s. Control sa.ples， instea.， relied onto the microbia. enzyme la.k. Twenty-four hours of simula.ed digestion were sufficient to completely hydrolyze gluten in one of the two MC-conta.ning experimenta. sets， a.d the rela.ive 48 h-digested extra.t did not a.ter the cytokine expression in duodena. biopsies from celia. disea.e (CeD) pa.ients. When digested sa.ples were a.sa.ed for a.tioxida.t a.d phyta.e a.tivities， microbia. enzymes demonstra.ed to significa.tly improve both a.TS a.d DPPH va.ues a.d to decrea.e the phytic a.id concentra.ion. The inspection of the free a.ino a.id profiles a.lowed for distinguishing the two MCs， wherea. the detection of a.heterogeneous pa.el of vola.ile orga.ic compounds supported the presence/a.tivity of microbia. enzymes without sta.istica.ly significa.t differences between MCs. a. functiona. contribution， digested extra.ts with MCs a.so proved to reduce the infla.ma.ory cytokine concentra.ions in cell lines exposed to lipopolysa.cha.ide trigger. Therefore， in line with studies exploring novel a.juva.t thera.ies， the present innova.ive probiotic consortium fea.ured by high gluten-hydrolyzing meta.olism a.so showed the ca.a.ility to improve va.ious pa.a.eters usua.ly found to be a.tered in pa.ients a.fected by gluten-ba.ed disorders or CeD.
