The aim of this study was to evaluate the biological and antimicrobial activities of commercial freeze-dried whey fermented by lactic acid bacteria in order to valorize this high polluting liquid waste of the dairy industry. Freeze-dried whey was fermented by different strains of Lactobacillus plantarum (CECT 220, 221, 748) at three different times of fermentation (24, 48, 72 h). Afterwards, the extract was purified on centricon amicon with a cut-off of 3 kDa to obtain a permeate consisting of small bioactive compounds reported in the literature to show greater bioactivity. The purified and diluted samples were subjected to the biological and antimicrobial tests for the evaluation of antioxidant, antihypertensive, iron binding, and antifungal activities and identification of phenolic compounds. The results highlighted a radical cation scavenging activity ranging from 1.415 to 2.083 mmol trolox equivalents TE per kg of dry weight, a percentage of iron binding capacity ranging between 23–55% and a percentage of ACE inhibitory activity ranging between 67–85%. The optimal biological activity was obtained from whey fermented by L. plantarum 220 for all the assays performed, except for the iron chelating activity. Furthermore, the antifungal analysis showed a good activity against the mycotoxigenic fungi belonging to Fusarium generum (F. moniliformis, F. graminearum and F. verticillioides), while a slight activity was obtained for Aspergillus and Penicillium generum. This antifungal activity could be correlated to the production of phenolic compounds during fermentation. The obtained results support the hypothesis of using whey as a functional ingredient to improve food preservation.

植物乳杆菌 不同菌株发酵冻干乳清的生物学和抗菌性能评价
这项研究的目的是评估由乳酸菌发酵的商业冻干乳清的生物学和抗菌活性，以评估乳业的这种高污染液体废物的价值。冷冻干燥的乳清用不同的植物乳杆菌菌株发酵（CECT 220、221、748）在三个不同的发酵时间（24、48、72小时）进行发酵。之后，将提取物在3 kDa的截止浓度的centricon amicon上纯化，以获得由文献中报道的具有较小生物活性的小生物活性化合物组成的渗透液。对纯化和稀释后的样品进行生物学和抗菌测试，以评估其抗氧化，降压，铁结合和抗真菌活性，并鉴定酚类化合物。结果表明，每千克干重的自由基阳离子清除活性范围为1.415至2.083 mmol trolox当量TE，铁结合能力的百分比在23–55％之间，ACE抑制活性的百分比在67–85％之间。从乳清发酵得到最佳的生物活性。除铁螯合活性外，植物乳杆菌220用于进行的所有测定。此外，抗真菌分析表明，它对镰孢镰刀菌属（F. moniliformis，F. graminearum和F. verticillioid es）的产毒毒素真菌具有良好的活性，而曲霉菌和青霉属的真菌则具有轻微的活性。这种抗真菌活性可能与发酵过程中酚类化合物的产生有关。获得的结果支持使用乳清作为功能成分改善食品保存的假设。
