Our company

Who we are


Leveraging 35+ years of microbiology expertise

to revolutionize water testing technology


BLUEPHAGE S.L. is a biotechnology company specializing in environmental testing solutions and launched as a spinoff company in 2016 from the University of Barcelona, Spain. Using a patent-protected accelerated coliphage indicator test, our microbiological water quality testing products detect bacteriophages as indicators of viruses that cause serious waterborne diseases. Our product pipeline will offer the fastest and easiest to use bacteriophage detection method currently available on the market for environmental testing of water.

BLUEPHAGE’s team of world renowned experts in basic and applied microbiology and virology in water testing methods tap into 35+ years of knowledge and know-how developed at the University of Barcelona within the MARS research group (Water Microbiology Related to Health).


Our Value Proposition


Testing for coliphages will become a new parameter

for routine water evaluation


Bacterial indicators fail to detect a broad range of enteric viruses in water samples and involve lengthy culture-based methods requiring extensive material prep time, skilled staff and special equipment. On top of these shortcoming, current testing for bacteriophages (specifically coliphages) using the EPA and ISO methods, takes nearly 48 hours to perform including material prep time. Shortcomings in traditional faecal indicator bacteria (FIB) testing methods has led to new state-of-the-art use of coliphages as more accurate viral indicators.

BLUEPHAGE’s rapid-steps lab kits include patent protected CRMs to monitor water quality for all types of water, food and biosolids. Easy to use, offering high sensitivity and rapid results under 5 hours, our lab kits provide the most reliable viral indicators for water safety monitoring.

Why bacteriophages


  • Bacteriophages tend to persist in the environment and are moderately resistant to natural and anthropogenic stressors. They can only replicate inside susceptible host bacteria. A given phage can only infect certain bacteria to the point that different strains of the same species differ in their susceptibility to phage attack. Bacteriophages like somatic and F- Specific coliphages are very good indicators because they persist usually longer than bacteria in the environment. When there are bacteriophages, other virus can be present in the environment but with lower concentrations. So, monitoring through this viral indicator can prevent some diseases related with other virus.
  • Bifidobacteria present some limitations as indicators because their environmental persistence is shorter than traditional bacterial indicators.
  • Fecal Coliformes have been used historically as a bacteria indicator.
  • Sulfite-reducing clostridia are bacteria with a very high persistence in the environment. So there are bad indicators for a fecal source.


Size and presence

  • In general, bacteriophages are viruses that infect bacteria and are extremely abundant in nature, probably the most abundant life form on Earth. In particular, bacteriophages outnumber bacteria in most habitats studied including microbial communities associated with humans and animals.
  • In a facility with filters, membranes or other technology, monitoring of bacteriophages provides greater safety than that of bacteria, due to their size (phages are smaller than bacteria) and greater abundance.
  • Bifidobacteria present some limitations as indicators because their environmental persistence is shorter than traditional bacterial indicators.
  • Fecal Coliformes have been used historically as a bacteria indicator.
  • Sulfite-reducing clostridia are bacteria with a very high persistence in the environment. So there are bad indicators for a fecal source.


Bacteriophages as a viral indicator

  • Many viruses are present in a fecal contamination, including norovirus, VHA, rotavirus, and adenovirus. It is complicated and expensive to analyze all types of virus, and for this reason it is necessary to select a virus as an indicator that shows the presence of the others. The indicator is good when its presence is higher and it is easier to enumerate than other viruses. Bacteriophages are used as fecal indicators as they mimic enteric viruses better than any other group of indicators since they fulfill these conditions, and show moderate resistance and persistence in the water environment and through wastewater treatment.
  • The appeal of phages as indicators lies in the availability of feasible, fast and cost-effective detection methods, and their abundance in wastewaters of human and animal origin. Moreover, samples can be kept at 4ºC for at least 48 hours without any significant change in the numbers of infectious bacteriophages and small samples can be kept for months at -20ºC or -80ºC after the addition of 10% v/v glycerol.
  • Reference suspensions of bacteriophages needed for quality assurance are easily prepared and conserved. Finally, phenomena such as stress, injury or reactivation that frequently lead to misinterpretation of environmental data derived from bacterial indicators do not affect bacteriophages.
  • The method of detection of infectious bacteriophages is through their effects, mostly lysis, on the host bacteria that they infect.
