Microbiology of Waste Water

Water from various sources, fresh, marine, ground, surface, recreational, agricultural and wastewater, are tested for microbial characterization, contamination source evaluation and environmental impact assessment. Detection and enumeration of indicator and specific organisms are performed using membrane filtration (MF), Most Probable Number (MPN) and pour plate (PP) methods.

Soil, Sludge and Sediment

Microbiological analysis is conducted on soil, sewage sludge and sediment samples for microbial characterization, evaluation and assessment. The most probable number (MPN) technique uses fermentation tubes for the detection of indicator organisms (coliforms) and sulphur oxidizers/reducers. Pour or Spread plate (PP or SP) and test tube (TT) methods are used for analysis of contaminant utilizing organisms. The pour plate (PP) and spread plate method (SP) is used for plate counts of bacteria and fungi. Additional analysis such as Microbial Biomass and Microbial Respiration are available.
