Product number: HAL009
Harlequin® membrane Lactose Glucuronide Agar (mLGA) is a medium for the detection and identification of E. coli and coliforms from water samples.
Harlequin membrane Lactose Glucuronide Agar (mLGA) was developed as a modification of mLSB for the recovery and identification of coliforms and E. coli. The medium has been modified to identify E. coli based on β-glucuronidase enzyme activity. Sodium pyruvate was also included in this formula to aid the recovery of chlorine stressed organisms. This medium is recommended for the enumeration of coliform bacteria and E. coli by a single membrane filtration technique in The Microbiology of Drinking Water 2009 (previously Report 71).
