Currently, biological method has been utilized in the treatment of wastewater -containing synthetic dyes used by textile industries in Iraq. The present work was devoted to study the operating feasibility using reverse osmosis (RO) and nanofiltration (NF) membrane systems as an alternative treatment method of wastewater discharged from Iraqi textile mills. Acid red, reactive black and reactive ...

Glucokinase from Bacillus stearothermophilus was irreversibly inactivated by the reactive dichlorotriazinyl dye Procion Blue MX-3G at pH 8.0. The enzyme was protected from inactivation by the substrate MgATP. Kinetic data implied that the dye occupied the MgATP-binding site. The apparent Km values for MgATP and D-glucose were found to be 70 microM and 210 microM respectively, and the Kd of the ...
