论文摘要
Halloumi是在塞浦路斯生产的半硬奶酪,在过去的几年中,其受欢迎程度显着增长。在本研究中应用了高通量测序(HTS),以表征传统的塞浦路斯Halloumi细菌多样性。分析了由不同牛奶混合物制成并在该国不同地区生产的18个样品,以揭示Halloumi微生物组主要由乳酸细菌(LAB)组成,包括乳酸菌,白细胞杆菌和Pediocococcus,Pediococcus,以及Halophilic Cabteria,以及诸如Marinililacibibacillomus and Halomonas and Halomonas。另外,还检测到形成细菌和变质细菌的孢子。与使用工业方法生产的Halloumi相比,使用传统方法生产的Halloumi具有更丰富的细菌多样性。在最终的微生物群组成形状中,在细菌群落中检测到的变化突出了牛奶中存在和幸存的最初微生物组的贡献,以及与Halloumi制造条件相关的因素。 Halloumi Microbiome的识别和表征提供了一种额外的有用工具来表征其典型性,并可能使其免受市场上可能出现的欺诈产品的保护。此外,它可以帮助生产者进一步提高其质量并确保消费者的安全。
Halloumi is a semi hard cheese produced in Cyprus for centuries and its popularity has significantly risen over the past years. High throughput sequencing (HTS) was applied in the present research to characterize traditional Cyprus Halloumi bacterial diversity. Eighteen samples made by different milk mixtures and produced in different areas of the country were analyzed, to reveal that Halloumi microbiome was mainly comprised by lactic acid bacteria (LAB), including Lactobacillus, Leuconostoc, and Pediococcus, as well as halophilic bacteria, such as Marinilactibacillus and Halomonas. Additionally, spore forming bacteria and spoilage bacteria, were also detected. Halloumi produced with the traditional method, had significantly richer bacterial diversity compared to Halloumi produced with the industrial method. Variations detected among the bacterial communities highlight the contribution of the initial microbiome that existed in milk and survived pasteurization, as well as factors associated with Halloumi manufacturing conditions, in the final microbiota composition shaping. Identification and characterization of Halloumi microbiome provides an additional, useful tool to characterize its typicity and probably safeguard it from fraud products that may appear in the market. Also, it may assist producers to further improve its quality and guarantee consumers safety.
