Biology and Microbiology Lab

Laboratorio de Biología y Microbiología

The Biology and Microbiology Laboratory supports water quality monitoring programs through standardized and innovative methods to achieve the objectives set by the Water Framework Directive (DMA 2000/60 / EC)


  • Identification and monitoring of cyanobacteria in water
  • Extraction and quantification of microcystins
  • Biodegradation analysis of microcystins
  • Analysis of microbiological indicators (E. coli, Enterococcos, Coliforms, Clostridium, Pseudomonas aeruginosa) to determine the quality of drinking and recreational waters
  • Analysis of biological indicators for the determination of the ecological state of the waters
  • Determination of Minimum Inhibitory Concentrations (MICs) of microorganisms (antibiograms)
  • Acute and chronic toxicity tests with algae, invertebrates and fish following standard protocols (ISO, OECD)
  • Microcosm and mesocosm tests at the population and community level


  • Microscopy unit: the microscopy unit is equipped with high-quality optical microscopes, with high-resolution photo-mounting systems, to facilitate identification and counting microscopic organisms:
