Identification and Detection of Marine Microorganisms

Marine microbial communities, including bacteria, viruses, and other microorganisms, have various advantages in biotechnological processes. In the detection of marine microorganisms, it is often necessary to detect certain groups of microorganisms, such as pathogenic bacteria, viruses, or microorganisms related to the safety of marine biological products. Detection of such microorganisms requires highly specific and high-accuracy detection techniques. Current detection methods include traditional classification and identification techniques, serological methods based on antigen-antibody reactions, and molecular biology methods based on specific gene detection. Conventional macroscopic colony morphology observation mainly observes the growth status of colonies on their suitable medium. Serological detection technology is based on the specific combination of antigen and antibody in immunology, which can detect antibody/antigen. Molecular detection technology is the main technical method for pathogen detection and diagnosis nowadays. It performs sequence amplification or specific probe binding based on a specific gene sequence of the target organism and performs electrophoresis, color development, or fluorescence to detect microorganisms.

Our Detection Technologies

  • Traditional classification and identification technology
    We stained the bacteria and observed them under a microscope. We choose the corresponding staining method according to the pre-determined observation items. The commonly used staining methods include gram staining, methylene blue staining, Ziehl-Neelsen staining, Giemsa staining, flagella staining, spore staining dyeing, etc.
  • Serological testing methods
    We identify marine microbes by enzyme-linked immunosorbent assay (ELISA) and immunosensors.
  • Molecular detection technology
    We detect marine microorganisms by real-time PCR, dot blot, in situ hybridization, and gene chip technology.
