Abstract
For construction of an efficient fats and oils-containing wastewater treatment, the specific microorganisms that can degrade fats and oils efficiently have been isolated and investigated. This review describes the recent studies of state and problem about microbial treatment of fats and oils-containing wastewater; the developments of the harmless fats and oils-degrading microorganism, the highspeed fats and oils-degrading microorganism, the high concentration fats and oils-degrading microorganism, the efficient combination for fats and oils-degrading microorganisms, and fats and oils-degrading microorganisms using a new evaluation method of fats and oils-degradation. In addition, monitoring microorganism number and specific microorganism using recent new techniques (DGGE and environmental DNA analytical methods) are also described.
