Physical and Chemical Properties	Bioactive hydrate is a fluorescent substrate (λex = 362 nm,λem = 445 nm).
In vitro study	4-Methylumbelliferyl-β-D-glucuronide hydrate is a fluorogenic substrat with λ ex =362 nm and λ em =445 nm. The half-saturation constants, K m , that are calculated for sewage samples are close to the K m values calculated based on experimental plots presented previously for freshwaters.
