| Research Abstract |
Biofilms are highly structured community of surface attached microorganisms. Cell density in biofilms is so high enough to enable the member cells to communicate each other very effectively and express specific genes. Experimental results unveiled several unique characteristics of the biofilm cells and molecular mechanisms behind. Moreover, applying high stress-tolerance of the biofilm cells to pollutant degrading bacteria was successful in constructing base of sustainable environmental biotechnology.
