Shubat is a traditional fermented camel milk drink that originated in Central Asia, with especially deep cultural roots in Kazakhstan. However, systematic studies on the microbial ecology and functional genes of Shubat remain scarce. As a distinctive fer-mented food, its microbial diversity and functional properties have not been fully ex-plored. This study investigates the microbial diversity and functional potential of Shubat by using advanced metagenomic techniques. Its microbial community is mainly composed of bacteria (96.6%), with Lactobacillus, Lactococcus, and Streptococcus being the dominant genera. Functional annotations through EggNOG, KEGG, and CAZy databases highlighted the metabolic versatility of Shubat's microbiota. Key pathways included amino acid and carbohydrate metabolism, vitamin biosynthesis, and central carbon metabolism, emphasizing their roles in fermentation and nutritional enhancement. The identification of various enzymes related to chemical synthesis further emphasizes the contribution of the microbiota to Shubat's unique flavor and texture. This study not only provides an important basis for the scientific understanding of Shubat but also expands the application possibilities of fermented food in the field of health and nutrition and confers modern value and significance to traditional food. This integration of science and tradition has not only facilitated the development of food microbiology but also paved new pathways for the global dissemination of traditional foods and the development of functional foods.
舒巴特是一种源自中亚的传统发酵骆驼奶饮品,在哈萨克斯坦有着尤为深厚的文化根基。然而,关于舒巴特微生物生态学和功能基因的系统性研究仍然匮乏。作为一种独特的发酵食品,其微生物多样性和功能特性尚未得到充分探索。本研究运用先进的宏基因组技术,对舒巴特的微生物多样性和功能潜力展开调查。其微生物群落主要由细菌组成(96.6%),其中乳杆菌属、乳球菌属和链球菌属为优势菌属。通过EggNOG、KEGG和CAZy数据库进行的功能注释突出了舒巴特微生物群的代谢多功能性。关键途径包括氨基酸和碳水化合物代谢、维生素生物合成以及中心碳代谢,凸显了它们在发酵和营养强化中的作用。对各种与化学合成相关酶的鉴定进一步强调了微生物群对舒巴特独特风味和质地的贡献。本研究不仅为科学认识舒巴特提供了重要依据,还拓展了发酵食品在健康与营养领域的应用可能性,并赋予传统食品现代价值和意义。这种科学与传统的融合不仅推动了食品微生物学的发展,也为传统食品的全球传播和功能性食品的开发开辟了新途径。
