The microbial community structure, species and abundance of the samples were determined by microbial community analysis methods such as clone library analysis, 16S rDNA amplicon sequencing analysis, and metagenomics sequencing.

After 60 years of continuous research and development, CICC has established an internationally leading and systematic platform for analyzing the structure of bacterial colonies, and the test reports issued are internationally recognized and legally valid. CICC can analyze the biodiversity of complex microbial samples by using techniques such as deformation gradient gel electrophoresis (DGGE), clone library analysis, 16S rDNA amplicon sequencing and metagenomic sequencing，investigating the spatial and temporal changes, evolutionary relationships, functional activities and interactions between environments of microbial communities, as well as accurately analyzing the species and abundance of low-abundance, difficult-to-culture or non-culturable microorganisms in the samples. Based on this, CICC can provide one-stop solution for R&D and innovation, product declaration, quality control, product distribution, and microorganism traceability of complex environmental samples or microbial contamination samples.
