MARINE MICROBIOLOGY LAB

The Marine Microbiology Lab is NABL accredited, offering a wide range of resources and support that assist scientists and researchers in monitoring coastal and marine microbiological testing and analysis. The facility is equipped with both classical and ‘state of art’ microbiology facilities for microbial identification and characterization. Dedicated facilities are provided for media preparation, chemical storage, Sterilization, Inoculation, Incubation, workstations for molecular analysis, and culture storage (-20°C). This national facility provides a unidirectional flow of work to facilitate a contamination-free environment from work station to storage

Analytical Capabilities:
  • Analysis of microbial water quality: Indicators and pathogens
  • Identification of bacteria
    • classical- Microscopy and physiological analysis by biochemical assay kits
    • Molecular-PCR and RT-PCR based identification of microbes and genes
    • Total microbial community analysis – Denaturing gradient gel electrophoresis (DGGE)
  • Protein profiling: Total and targeted protein profiling by SDS-PAGE
  • Photometric, fluorometric, and luminometric analysis of water and biological samples in microgram quantities

THEMATIC AREAS

  • Marine Microbial Ecology
  • Beach water microbiology
  • Microbial functional dynamics
