| Abstract | Naturally fermented yak milk (NFYM) is a traditional Tibetan fermented product that contains a rich microbial community. This study used high-throughput pyrosequencing to investigate the bacterial and fungal community diversity of 16 NFYM samples from the villages Geda and Ningzhong in Tibet. Pyrosequencing produced a total of 112,173 high quality bacterial 16S rRNA gene sequences and 90,980 fungal high quality reads from the NFYM. Sequence analysis grouped the high quality gene sequences into eleven bacterial and five fungal phyla, of which Firmicutes and Ascomycota dominated. At the genus level, Lactobacillus and Saccharomyces were the dominating bacteria and fungi, respectively. Principal coordinate analysis (PCoA) based on weighted and unweighted UniFrac values revealed no significant differences in the structure of bacterial and fungal microbiota. However, multivariate analysis of variance (MANOVA) based on unweighted UniFrac distances showed significant differences (P < 0.05) between the bacterial and fungal populations of the two NFYM samples from different villages. After the redundancy analysis (RDA), 49 key responding operational taxonomic units (OTUs) could be identified. Among them, 7 OTUs (Acinetobacter, unidentified Bacteroidetes, Lactobacillus, unidentified Proteobacteria, Streptococcus, Pantoea, and unidentified Firmicutes) were enriched in the Geda village samples, while 42 OTUs (mainly Massilia, Propionibacterium, Lactococcus, Leuconostoc, and Enterococcus) were enriched in the Ningzhong village samples. The present work provided insights into the microbiome of Tibetan NFYM and showed that the microbiota composition may be stratified by their geographic regions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
