  • Colifast
    Rapid, Automated and Remote Microbial Testing for Water and Food Safety Colifast ALARM™ is an electronic instrument for detecting indicator bacteria in drinking water using patented Colifast technology. 100 ml water samples are automatically collected at programmed intervals and analyzed for total coliforms, thermotolerant coliform bacteria or E. coli. In addition to performing rapid, online microbial water analysis, Colifast ALARM measures water turbidity. The system can automatically send results to control rooms / operators via LAN, digital signals or via mobile networks (SMS). The system can detect down to 1 cfu / 100 mL, and results are achieved within 6-14 / 15 hours. Technology The main components of Colifast ALARM are the incubator chamber, an injection pump system for fluid handling, and a detector system that includes wavelength-specific emitters combined with a spectrometer. Detection of down to 1 viable target bacteria is based on bacterial growth, group-specific enzyme activity and measured concentrations of a fluorescent product (ppb MU). An increase in the number of target bacteria means an increase in the amount of β-D-glucuronidase (E. coli-specific enzyme). The enzyme hydrolyses the growth medium substrate to MU (the fluorescent product) and β-D-glucuronic acid. Increased MU release gives increased fluorescence signal on the Colifast ALARM. Colifast growth medium contains inhibitors to prevent growth of non-coliforms. Colifast ALARM is verified by EPA's ETV program.

    The Colifast At-Line Monitor – CALM is a fully automated early warning system for monitoring of coliforms and Pseudomonas aeruginosa in water. Detection time ranges from 2 to 12 hours. The technology is time-saving, cost-reducing, and environmentally friendly. Examples of CALM applications are monitoring of raw water, in-process water, waste water and recreational water. No laboratory facilities and minimal skills in microbiology are required to operate the instrument. The Colifast CALM is easily connected to the system computer or LAN interface. The patented Colifast growth media are supplied in Pre-filled Multi Well Trays™ and the flexibility of the system makes it easy to adapt to different applications. The CALM can perform parallel analysis of different target organisms. Depending on method and test frequency, the CALM needs monthly or weekly refilling of reagents. Technology The CALM instrument detects and quantifies E. coli, fecal or total coliform bacteria in water by fluorometric monitoring of β-glucuronidase activity (E. coli) or β-galactosidase activity (fecal and total coliforms). The detection of P. aeruginosa is based on substrate hydrolysis of aminopeptidase enzymes present in this bacterium. The Colifast technology is comprised of unique media formulations combined with instrument detection systems. The technology is covered by patents in numerous countries, with several international patents pending. Growth of other bacteria is stopped by inhibitors in the medium and by incubation of the samples at high temperature: Incubator temperatures for selection of thermotolerant coliform bacteria are 44 ° C and total coliforms / E. coli are 37 ° C. Method The instrument can perform one of two methods at a time. The Most Probable Number (MPN) method is based on the cultivation of bacteria. A certain volume is added to 4-6 wells of growth medium and the bacterial number is determined from how many of the wells that gave growth after the incubation period (11-12 hours). For the results to be as accurate as possible, it is therefore important that the samples taken on a given source usually give a mixture of positive and negative results. The rapid method is also a quantitative method, which is based on the enzyme activity of the bacteria present in the water sample. It provides response after 75-115 min and is suitable for water sources where major contamination events can occur. The CALM is a flexible instrument. This means that the instrument can be adapted to different locations with different occurrence of bacteria. If a source has an average bacterial count of 500 cfu / 100ml, 0.2 ml will usually give a positive test. By injecting about half of this volume, you will often get both positive and negative samples. If the source has lower concentrations of bacteria, the media concentration can be changed so that the sample volume can be as high as 10 ml. In this way, we ensure good results from the CALM instrument with optimal concentration of media after addition of sample and a sample volume appropriate for the source being measured.

    Colifast Field Kit is a portable tool for field detection of coliform bacteria in water. The main method of the kit is a rapid method that provides an answer as early as 15 minutes, 2 hours at the latest. In addition, the kit includes methods for a quantitative MPN (Most Probable Number) method and presence/absence results. The procedure is very easy to perform, and requires no laboratory skills. Colifast Field Kit is delivered in a robust and portable metal case, and all equipment required for the water analysis is included. The Colifast Micro Detector (CMD) is used in combination with a growth medium for specific detection of target bacteria. Combined, they provide a simple instrumental analysis and rapid results that quantify the amount of coliform and thermotolerant bacteria in water. The method is based upon the patented technology of Colifast AS. The system detects down to 1 target bacterium per sample volume. Method The Colifast technology is based on a chemical reaction between a substrate in the growth medium and enzymes produced by the coliform bacteria. The bacterial enzyme β-D-galactosidase hydrolyses the substrate 4-methylumbelliferyl-β-D-galactoside, which results in the release of the fluorescent product 4-methylumbelliferone (MU). In addition to substrate, activators and growth factors, the medium comprises inhibitors that prevent the growth of non-coliform bacteria. The results are measured in fluorescent units. An increase in the number of bacteria corresponds to an increased amount of β-D-galactosidase (enzyme). The subsequent increase in the amount of MU (fluorescent product) results in a higher value on the instrument (Colifast Micro Detector). The incubation temperature selects for thermotolerant coliforms at 44 °C and total coliforms at 37 °C.

    Protein Enzyme-Linked Immunosorbent Assay (ELISA) Tests for allergen proteins. The Neogen Allergen Protein ELISA Kits utilise a sandwich ELISA. The target protein present in the sample react with the specific antibodies, which have been adsorbed to the surface of polystyrene microtiter wells. After the removal of unbound proteins by washing, antibodies conjugated with horseradish peroxidase (HRP) are added. This enzyme-labeled antibody forms complexes with the previously bound target protein. Following a second washing step, the enzyme bound to the immunosorbent is detected by the addition of a chromogenic substrate, 3,3’,5,5’-tetramethylbenzidine (TMB). The colour development from this enzymatic reaction varies directly with the concentration of target protein in the sample tested; thus, the absorbance, at 450 nm, is a measure of the concentration of the target protein in the test sample. The quantity of protein in the test sample can be extrapolated from the standard curve, constructed from standards of known concentration, and adjusted to consider the sample dilution.
