Full textROQUETTE transforms and valorizes peas (Pisum sativum) to produce proteins, fibers and starches. During this process, various secondary fractions are generated, including the pea soluble, designated LAB 4960 after atomization. This fiber-rich co-product is unfit for human consumption in its current form as it can cause digestive disorders, caused by the high content of α-GOS, α-galactooligosaccharides formed from 1 to 3 galactose units linked by α-(1-6) bonds. Among the α-GOS are raffinose, stachyose and verbascose which are not digested by humans, but fermented by the intestinal microbiota. The aim of this thesis project is therefore to reduce the α-GOS content of LAB 4960 by microbial fermentation in order to improve its digestibility. To achieve this objective, a twofold strategy has been implemented. In a first part, a microbial collection that is very diverse in terms of species and ori-gins (plant vs. animal) was built up from pea seeds with the characteri-zation of the microbial diversity of peas from different terroirs and from the private collections of the INRAE Laboratory and the ROQUETTE Company. In a second part, the constituted collection was tested for its ability to hydrolyze the α-GOS from LAB 4960. The screening of the strains was split into three steps, involving different selection criteria. Step 1 allowed the selection of strains capable of growing on LAB 4960 agar under two conditions of oxygenation (aerobic and anaerobic) and pH (acidic and neutral). Step 2 allowed the identification of sugars by Thin-layer chromatography after 72 hours of culture on the liquid LAB 4960. The strains that reduced the α-GOS were selected in step 3 for the quantification of sugars by High performance liquid chromatog-raphy coupled to mass spectrometry. In the first part, the metagenetic study of pea surface diversity according to different terroirs after soak-ing, showed a strong dominance of bacterial species belonging to Proteobacteria (57%) and Firmicutes (28%) and fungal species be-longing to Ascomycota (89%) and Basidiomycota (11%). The structure of the epiphytic community associated with the pea seed was strong-ly influenced by its origin (storage cooperatives and countries). From the pea seed soaking juice, 102 strains were isolated and assigned to 52 species. The 52 pea strains representative of each identified spe-cies were added to the 157 strains representative of 82 microbial species in the internal collections. Screening of the collection showed that 89% of the strains tested were capable of growing on LAB 4960 agar. About 20% of the strains degraded only sucrose. The occurrence of sugars as melibiose, manninotriose and manninotetraose, known to be the product of defructosylation, suggested that 19% of the strains hydrolyzed α-GOS by a β-fructosyltransferase of which 4% came from peas. Finally, 4% of the strains hydrolyzed α-GOS by an α-galactosidase, of which 1% came from peas. Among the 23% strains hydrolyzing α-GOS, two strains stood out for their strong hydrolytic activity: Candida pseudoglaebosa CBS 6715T and Serratia liquefa-ciens GBM09. A study on minimum medium, LAB 4960 medium and in a bioreactor on LAB 4960 of different concentrations showed that, under optimal growth conditions, the GBM09 bacterium is capable of hydrolyzing the α-GOS in increasing order of degree of polymeriza-tion at neutral pH and at 20°C whereas the yeast CBS 6715T hydro-lyzes all the α-GOS simultaneously at acid pH and at 28°C.These preliminary trials have made it possible to validate a proof of con-cept for a fermented functional food and hold out promise of their development on an industrial scale, paving the way for many innova-tions

Full textThe effects of cold acclimation on pea cell wall metabolism were investigated, using an integrated approach, on one frost-tolerant genotype (Champagne, C) and one frostsensitive genotype (Terese, T). Plants were grown under controlled conditions and stipules of cold (CA) - and non-cold-acclimated (NA) plants were harvested at different time points. Cell wall non cellulosic neutral sugar composition, uronic acid content and their degree of methylesterification (DM) were determined using combined approaches including Gas Chromatography (GC), Fourier Transform InfraRed spectroscopy (FTIR) and immunolocalization of pectic epitopes using specific antibodies. The changes in transcript levels of cell wall-related enzymes were investigated using microarrays and the activities of pectin remodeling enzymes were determined. Cold induced differential expression of transcripts encoding cell wall proteins/enzymes. It had consequences on cell wall composition, with opposite changes in the content of arabinose, xylose and galactose residues in Champagne and Terese. Cold acclimation induced an increase in the DM, notably observed by a greater JIM7 labeling in Champagne compared to Terese. Our study demonstrate that, in vegetative tissue of pea, specific changes in neutral sugars and DM is likely to lead to changes in pectin solubilisation, in polymers interactions and an increase in cell wall rigidity during cold acclimation is observed. Our work paves the way for using, in quantitative genetics studies, cell wall determinants as criteria for discriminating between genotypes with contrasting cold tolerance behaviour
