Abstract

The current research has shown promising potential for the application of the endemic, indigenous, non-pathogenic and heavy-metal-tolerant marine sediment bacteria isolated from Iligan Bay in the bioremediation of solid waste or wastewater contaminated with the heavy metals Pb and Cd. Optical density, wet-weight differential, paper disc diffusion, biosorption efficiency, quantification of the metallothionein, and in situ protein reactivity profile using the 10% SDS-PAGE have shown a potential of metal uptake by the bacteria. Reactivity with the target protein having the MW of ~39 kDa formed the complex having a MW of ~42 kDa.
