Multi-source Microbial Community Analysis Service (16S/ITS Metagenomics)

Metagenomics, also known as Environmental Genomics, is the scientific study of an entire microbial community. It involves extracting DNA from environmental samples containing microorganisms, sequencing the DNA, and then conducting analyses such as species identification, phylogenetic assessments, gene function studies, and phenotype correlations. The aim is to gain insights into the diversity of microorganisms present in the environment.

The 16S rRNA gene is present in the ribosomes of all bacteria and exhibits highly conserved sequences as well as diverse features among different bacterial species. Consequently, it serves as a valuable marker for bacterial classification and identification. 16S metagenomics primarily focuses on the sequencing of the 16S rRNA gene sequences of bacteria. This involves amplifying rRNA fragments through PCR, constructing paired-end libraries, and utilizing the Illumina MiSeq platform for sequencing. Subsequently, the obtained sequences are analyzed to determine the bacterial taxa and their distribution proportions in each sample based on sequence variations and abundance.

In summary, the application of metagenomics provides a comprehensive and in-depth understanding of microbial community structure and function. This approach is crucial for ecological studies, environmental science, and research related to microbial health.

Bacteria Genome Sequencing Finish Map

Combining the advantages of next generation sequencing (NGS) and third generation sequencing platform Nanopore, we present a fully confirmed bacterial whole-genome assembly. The Nanopore platform provides long read sequences, yielding superior results in genome assembly, structural variation detection, and identification of continuous repetitive sequences. This is complemented by the high coverage depth and precise sequencing quality of Illumina NGS data, enabling the accurate assembly of a comprehensive and precise genome map.

The report includes quality control (QC) of samples and data, sequence assembly and alignment (using BlastN, BlastX), gene annotation, database analyses (GO, COG, KEGG), and a Genome map. Additionally, we provide data for uploading and registering in the NCBI genome database, along with information relevant to genome patent registration.

By leveraging the strengths of both NGS and Nanopore third generation sequencing platforms, we ensure a 100% confirmed bacterial whole-genome assembly. The long read sequences from Nanopore facilitate superior genome assembly, especially in discerning structural variations and identifying continuous repetitive sequences. When combined with the high coverage depth and precise sequencing quality of Illumina NGS data, our approach results in the accurate assembly of a comprehensive and precise whole-genome map.

The report encompasses QC of samples and data, sequence assembly and alignment using tools such as BlastN and BlastX, gene annotation, database analyses including GO, COG, and KEGG, as well as a Genome map. Moreover, it provides the necessary data for uploading to and registering in the NCBI genome database, along with information pertinent to genome patent registration.
