Multiple Enzyme Technology Standard Plate-count Bacteria For water testing
Item Name Multiple Enzyme Technology Standard Plate-count Bacteria
Scientific principles
The total bacterial count detection reagent uses enzyme substrate technology to detect the total bacterial count in water. The reagent contains a variety of unique enzyme substrates, each designed for different bacterial enzymes. When different enzyme substrates are decomposed by enzymes released by different bacteria, they release fluorescent groups. By observing the number of fluorescent cells under the ultraviolet lamp with the wavelength of 365 nm or 366 nm, the total value of colonies can be obtained by looking up the table.

Science
Add water sample containing Enterococcus bacteria, culture the target bacteria in Mug medium at 41°C 土 0.5°C, and the specific 切 ological enzymes produced by Enterococcus bacteria(3 -0 -gluco sidase can decompose the
fluorescent substrate mug in the mug medium to produce(3 -D-glucoside ((3 -0 -glucoside) and the
characteristic fluorescent product 4-methyl umbelliferone. Observe the fluorescence in the 366nm UV lamp, count through the quantitative detection disk, and query the MPN table to calculate the results.

Cotiform Group Enzvme substrate detection reagent For water testing
Item Name ：Cotiform Group Enzvme substrate detection reagent
Character This product is white or light yellow particles
Clarification degree Colorless or slightly yellow
PH 7.0-7.8
Weight 2.7士 0.5 g
Storage: Long term storage, drying, sealing and avoiding light storage at 4°C – 8°C
Term of Validity 1 years
Working Principle
In the water samples containing total coliform bacteria, the target bacteria were cultured in the ONPG-MUG medium at 36 土 1 C. The specific enzyme betagalactosidase produced by the total coliform bacteria can decompose the color source substrate of the ONPG-MUG medium, which makes the culture medium yellow; meanwhile, Escherichia coli produces a specific beta-glucuronase to decompose the fluorescent substrate MUG in ONPG-MUG medium and produce characteristic fluorescence. The same principle, the heat tolerance coliform group (fecal coliform group) will decompose the color source substrate ONPG in the ONPG-MUG medium at
44.5 土 0 . 5 °C, making the medium yellow -
100ml sterile sampling bottle / quantitative bottle For water testing
The 100ml sterile sampling bottle / quantitative bottle produced by Lifecosm Biotech Limited. is mainly used for the determination of water samples of coliform bacteria by enzyme substrate method. 100ml sterile sampling bottle / quantitative bottle is a product with 51-hole or 97-hole quantitative detection plate, Lifecosm enzyme substrate reagent and program controlled quantitative sealer. According to the instructions, 100ml water samples were accurately measured with 100ml aseptic sampling bottle / quantitative bottle. The reagents were dissolved in the quantitative detection plate / quantitative hole plate, then seal plate with a program-controlled quantitative sealing machine and culture it about 24h, then count the positive cells. Check the MPN table to calculate.
Sterilization instructions
Each batch of 100ml aseptle samples bottle was sterilized before leaving factory 1 years of validity.

51 hole detection plate For water testing
The 51 hole detection plate produced by Lifecosm Biotech Limited. It is used together with the enzyme substrate detection reagent to accurately determine the MPN value of coliform in 100ml water samples. According to the instructions of the enzyme substrate reagent, the reagent and the water sample are dissolved, and then poured into the detection plate, and then cultivated after sealed with sealing machine, the positive pole are counted, then calculate the MPN value in the water sample according to the MPN table
Packing specification：Each box contains 100 51- hole detection plates.
Sterilization instructions：Each batch of 51 hole detection plates were sterilized before they were released. The period of validity is 1 years.
