Marine Microbial Community Profiling

Marine microbial communities are composed of bacteria, archaea, protists, fungi, and viruses. In its normal state, the microbiota consists of microorganisms that co-exist with each other and with the host. It is a homeostatic dialogue that affects different physiological systems. In dysbiosis, this dialogue is disrupted and can lead to many pathologies. Observations and analyses of marine microbial community dynamics provide insights into how microbes are affected by the environment and other microbes. Marine microbes are explored from a variety of challenging and interesting extreme environments, suggesting emerging new tools to examine, detect, and characterize microbes. DNA sequence-based metagenomics has become a standard tool for analyzing natural microbial communities in marine environments. It involves sequencing random community DNA in environmental samples and subsequently determining taxonomic and protein-coding gene diversity. At CD BioSciences, our microbial ecologists apply metagenomics, metatranscriptomics, metaproteomics, metametabolomics, and other related techniques to study marine microbial communities in order to improve culture-independent molecular methods.

Our Services

CD BioSciences supports the development of various marine microorganisms and microbial community profiling. Depending on their target, different microbiota and bacteria can be studied in complex marine environments. Our services are listed as follows, but are not limited to:

  • Bacterial Profiling Analysis
    Our scientists explore the bacterial world of the ocean through targeted 16S rRNA metabarcoding sequencing.
  • Fungal Profiling Analysis
    Our scientists have brought us tremendously closer to the hidden world of fungi by using a culture-independent approach to ITS (internal transcriptional spacer) metabarcoding sequencing. With the application of metabarcoding analysis, fungal community structure from a wide range of marine environmental niches has been explored.
  • Eukaryotic Profiling Analysis
    Our scientists use a culture-free approach to 18S rRNA metabarcoding sequencing, which greatly brings us closer to the hidden world of eukaryotic cells.
  • Microbiome Description
    • Next-generation sequencing to characterize the microbiome through metagenomic and metatranscriptomic analysis
    • Post-metagenomic studies to explain candidate-induced microbiota evolution
  • The Abundance and Diversity Analysis of Marine Microbiomes
    At CD BioSciences, high-throughput targeting of phylogenetic marker genes, such as small subunits of 16S rRNA, is for direct exploration of marine microbiome abundance and diversity in natural aquatic environments.
