ABSTRACTAnaerobic technology has become widely accepted by the environmental industry as a cost-effective alternative to the conventional aerobic process. In addition, with the intrinsic advantages of energy saving, reduced sludge yield, and production of biofuel, anaerobic process will be the favored green treatment technology for sustainable environment in years to come.Written by 40 renowned experts from 13 countries/regions, this book consists of 18 chapters compiling state-of-the-art information on new developments in various aspects of anaerobic technology. These include development of new types of reactors, uses of molecular techniques for microbial studies and mathematical modeling, productions of bio-hydrogen by fermentation and microbial electrolysis cell, as well as broadening applications to the treatment of municipal wastewater, effluents from chemical industry and agricultural wastes with high lignocellulose content.

"Prevotella intermedia and Porphyromonas gingivalis are two of the specific microorganisms that frequently occurs in chronic periodontitis. As protein plays an important role in bacteria's life and it's virulence factor, we tried to explore variation in P. imtermedia and P. gingivalis were identified using Polymerase Chain Reaction (PCR) technique, and it's protein profile were evaluated using Sodium Dodecyl Sulfate - Polyacrylamide Gel Electrophoresis (SDS-PAGE). SDS-PAGE result showed that there were significant difference between protein profile of P. intermedia cell which isolated from shallow and deep pocket with dominant proteins of molecular weight 200 kDa, 110 kDa, 40 kDa, and 25 kDa, however, relationship between pocket depth and P. intermedia cell protein profile could not be concluded because unrepresentative number of P. intermedia colonies. In the other hand the variation in P. gingivalis cell protein profile was not influenced by pocket depth with dominant protein called hemin binding protein (HbBp)."
