Abstract Biopreservation is a promising technology for insuring safety of food. This study evaluated the anti-Salmonella potential of 1450 dairy isolates from 54 genera, in conditions mimicking dairy matrices, to find new bioprotective strains. Among the screened isolates, 6.4% exhibited an antagonistic activity towards at least one of the two Salmonella Mbandaka and Montevideo reference strains. Lactococcus sp. generated the highest number of bioprotective candidates, followed by Aerococcus sp. from which seven isolates were able to inhibit at least 80% of 20 Salmonella strains in milk synthetic medium, and/or in cheese synthetic medium. Inhibition by Aerococcus sp. was characterised by the production of hydrogen peroxide (30 to 100 mg L-1) and acetic acid (0.25 to 0.34 g L-1). Aerococcus sp. appears to be a new promising source of bioprotective agents against Salmonella in dairy matrices, along with the well-described Lactococcus genus.

气球菌属，一种很有前途的属，可作为乳制品行业抗沙门氏菌生物保护剂的来源，通过小型化筛选方法揭示

摘要 生物保鲜技术是保证食品安全的一项很有前景的技术。该研究评估了来自 54 个属的 1450 种乳品分离物在模拟乳制品基质的条件下的抗沙门氏菌潜力，以寻找新的生物保护菌株。在筛选的分离株中，6.4% 对两种沙门氏菌 Mbandaka 和蒙得维的亚参考菌株中的至少一种表现出拮抗活性。乳球菌属 产生最多的生物保护候选物，其次是气球菌。其中 7 个分离株能够抑制牛奶合成培养基和/或奶酪合成培养基中的 20 种沙门氏菌菌株中的至少 80%。气球菌的抑制作用。其特征在于产生过氧化氢（30 至 100 mg L-1）和乙酸（0.25 至 0.34 g L-1）。气球菌属
