Rapid Biomonitoring of Heavy Metals in Polluted Sites Using Xenoassay®-Metal

Long-term water contamination, including heavy metals, may harm the reputation of location. Because this, it is necessary to do regular quality checks. In light high expense instrument monitoring, biomonitoring based on enzymes rapidly gaining popularity around world. For purpose this investigation, a molybdenum-reducing enzyme from Serratia marcescens strain DRY6 that sensitive metals was used build quick inhibitory assay. The bacterium's activity extremely vulnerable metals. With help established assay, were detected in samples collected Malacca, Penang, and Perak. A number sampling locations Penang found be inhibiting activity, while all Malacca confirmed free metal concentrations. Malaysian Department Environment has set maximum permissible limit for suppression Mo-reducing Penang. Detection can done less than ten min at room temperature. entire procedure takes 20 min. first screening or even near real-time method routine monitoring assay straightforward.
