OUR EXPERIENCE AT YOUR DISPOSAL

Phage Consultants helps companies fight and prevent bacteriophage infection.

Phage contaminations threaten fermentation processes based on bacterial activities and pose a serious risk to companies relying on such bioprocesses, occasionally resulting in a complete paralysis of facility’s productivity. Although even the best practices do not guarantee contamination-free production, better prepared facility will recover faster, and the contamination will not turn into an outbreak.

PHAGE CONSULTANTS specializes in prevention and troubleshooting of phage contamination problems in various production and laboratory setups through a variety of services. We offer phage detection and identification services, facility audits and initial assessments, consultations, personnel training, advice on bioprocess optimization and SOP improvement, and new facility development. We also offer fast and reliable routine or as-required testing of incoming bacterial strains and cell banks for the presence of both lytic phages and prophages – a necessary tool in phage prevention. With these services, Phage Consultants can help you avoid phage contaminations and recover quickly from contaminations that have already occurred.

Our team of expert scientists working in state-of-the-art laboratories are ready to solve all bacteriophage-related problems. Not only can we help with phage contaminations, but we can also offer assistance with all aspects of bacteriophage use in various fields of biotechnology, medicine, food and crop protection etc., as well as contract phage manufacturing and phage purification services. Our extensive expertise in phage biology research helps us deliver high quality results in relatively short time and at competitive prices.

Since its establishment in 2007, Phage Consultants has successfully completed over 150 phage prevention and troubleshooting jobs worldwide (see the map below), and remains a global leader in prevention and resolution of phage-related production irregularities.
