Decontamination of Environmental Water Sources Using Living Engineered Biofilm Materials

A living engineered biofilm material configured for decontamination of an environmental water source, wherein the biofilm material comprises microbial cells embedded in a protective extracellular matrix comprising a fusion protein expressed by the microbial cells, the fusion protein comprising an amyloid domain and a contaminant binding domain operative to bind a contaminant of the water source, and thereby facilitate decontamination of the water source.
