| Abstract | The permafrost soil of Mo-he in Northeast China presents a typical cold environment colonized by psychrophilic microorganisms. This study is aimed at assessing the bacterial communities of permafrost soil of Mo-he in China by sequencing the 16S rRNA genes and Mothur analysis. PCR products with universal 16S rRNA gene primers were cloned and partially sequenced, and bacterial identification at the species was performed by comparative analysis with the GenBank/EMBL/DDBJ database. A total of 266 clones were obtained with the average length of 1,050 bp. Mothur analysis showed that the coverage value of clone library was 53.78 %, Shannon diversity (H) was 4.03, Simpson diversity value was 0.018, and 74 operational taxonomic units were generated. Through phylogenetic assignment using BLASTN by more than 97 % similarity, a total of 87 tentative taxa were identified. The majority of bacterial sequences recovered in this study belonged to the Acidobacteria, Proteobacteria, Verrucomicrobia, Bacteroidetes, Chloroflexi and Chlorobi. Among them, Acidobacteria are dominant community, accounting for 30.1 % of total bacteria, followed by Proteobacteria which accounted for 22.2 %. This result reflected the acidic characteristics of the permafrost soil of which pH value was 6.0. Our study indicated that the permafrost soil of Mo-he in China has a high diversity of bacteria and represents a vast potential resource of novel bacteria. As far as we knew, this is the first report on bacterial diversity of permafrost soil of Mo-he in China. |

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.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
