“…Some other profiling techniques, such as community-level physiological profiling, restriction fragment length polymorphism, denaturing gradient gel electrophoresis, and phospholipid fatty acid profiling, have been applied to investigate the composition of bacterial community in contaminated aquifers near MSW composting sites (Röling et al, 2000;Tian et al, 2005;Yu et al, 2010). Among available DNA profiling techniques, TRFLP has been used to monitor structural changes of various soil microbial communities (Dunbar et al, 2000;Singh et al, 2006;Grant et al, 2007).…”
