GL Biocontrol
About
GL Biocontrol is a French biotechnology firm headquartered in Clapiers near Montpellier, with a regional office in Maxéville (Grand Est), specializing in rapid microbiological water testing through ATP-metry technology. Founded in 2008, the company manufactures the DENDRIDIAG line of field kits that quantify bacterial load in water within approximately two minutes by measuring intracellular adenosine triphosphate. The product range addresses distinct water matrices: drinking water (DENDRIDIAG SW), domestic hot and cold water systems, industrial and process water including cooling towers (DENDRIDIAG IW), ultra-pure water for pharmaceutical, cosmetic, haemodialysis, and microelectronics applications (DENDRIDIAG UPW), and surface microbial analysis (DENDRIDIAG BF). Each kit employs a four-step protocol—filtration, ATP extraction, luminometer quantification, and internal validation—that eliminates free ATP and inhibitors to avoid false negatives. Results are displayed in pg ATP/mL, equivalent bacteria/mL, and log equivalents via the companion DENDRIDIAG WebApp. Beyond ATP kits, GL Biocontrol produces coliphage concentration kits and PhiX174 and MS2 positive controls for virus enumeration in water. Their consulting bureau delivers roughly 150 expert assessments per year, including Legionella risk diagnostics, methodical risk analysis for cooling installations and domestic hot water systems, microbiologically influenced corrosion diagnosis by qPCR, and ATP cartography mapping. The company processes approximately 100,000 ATP measurements annually across over 500 equipped sites serving clients such as SUEZ, Veolia, ENGIE, STMicroelectronics, and Eurofins. GL Biocontrol joined LuminUltra in September 2025.
