Terminal restriction fragment length polymorphism analysis is popularly used as fast and reliable method to investigate the profile of microbial communities in environmental samples. It can be used as a fingerprinting technique to investigate the structure and composition of bacteria that are present in the wastewater treatment processes. In this project, I developed a T-RFLP method for wastewater sludge and used this method to investigate the bacterial community in sludge from four membrane bioreactors. DNA extracted from bioreactor sludge samples underwent Polymerase Chain Reaction to amplify the 16S rRNA gene; this amplicon then underwent PCR product purification, and the purified amplicon was finally enzyme digestion whereby a variety of enzymes were used to obtain Terminal-Restriction Fragments.
