Microbial Stability Evaluation of Waste Containment Materials Using a Biofilm Formation Approach

摘要

A biofilm formation method was used to evaluate the stability of a phosphate-bonded ceramic(PBC)waste form(waste containment material), a cement/manganese tailings waste form, and a ceramic-coated metal strip, in the presence of Thiobacillus thioocidans. All the waste disposal aterials ealuated showed ev- idence of the growth of biofilm on their surfaces, and exhibited degrees of susceptibility to mi- crobial degradation.
