Flaxseed and soybean are an important source of phytochemical compounds, mainly lignans and isoflavones, but also of flavones, flavanones and flavonols. These compounds appear mainly glycosylated in plant food and are converted into aglycones by the intestinal microbiota, increasing their bioavailability. In this work, we analyse the ability of Bifidobacterium strains (n = 25) to produce lignan and flavonoids aglycones from flaxseed and soybean extracts. Most of the Bifidobacterium strains increased the concentrations of secoisolariciresinol, daidzein, genistein, naringenin, eriodyctiol, luteolin and apigenin. Moreover, Bifidobacterium pseudocatenulatum and Bifidobacterium breve strains showed high production of herbacetin, increased the kaempferol concentration and produced quercetin and quercetagetin. B. pseudocatenulatum INIA P815 and B. breve INIA P367 produced 32.37 ± 2.81 and 28.64 ± 3.36 mg respectively of herbacetin g−1 of lignan extract. Bifidobacterium strains transformed the glycosides of a wide range of flavonoids into their aglycones, increasing the antioxidant activity and improving their bioavailability.

双歧杆菌菌株从亚麻籽和大豆提取物中生产类黄酮和木脂素苷元
亚麻籽和大豆是植物化学化合物的重要来源，主要是木脂素和异黄酮，但也包括黄酮，黄烷酮和黄酮醇。这些化合物主要出现在植物性食物中，被糖基化，并被肠道菌群转化为糖苷配基，从而提高了它们的生物利用度。在这项工作中，我们分析了双歧杆菌菌株（n = 25）从亚麻籽和大豆提取物中生产木脂素和类黄酮苷元的能力。大多数双歧杆菌菌株均增加了椰油异麦芽烯醇，黄豆苷元，染料木黄酮，柚皮苷，紫杉醇，木犀草素和芹菜素的浓度。此外，假双歧杆菌和短双歧杆菌菌株显示了高产草精素，增加了山emp酚的浓度，并产生了槲皮素和槲皮素。假链球菌INIA P815和短短芽孢杆菌INIA P367分别产生32.37±2.81和28.64±3.36 mg的除草素g -1木质素提取物。双歧杆菌菌株将多种类黄酮的糖苷转化为其糖苷配基，从而提高了抗氧化活性并提高了其生物利用度。
