Marine Microbiology Lab

 / Services / Laboratory Facilities / 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
