To provide a styrene oligomer degrading method that degrades styrene oligomers consisting of three or more monomers, accumulated in the ocean, lakes, rivers or the like, particularly styrene trimers, into styrene dimers or styrene monomers, and styrene oligomer degrading bacteria for use in the method.SOLUTION: A styrene oligomer degrading method includes mixing styrene oligomers consisting of three or more monomers in contaminated water with a suspension comprising marine bacteria, thereby degrading them into styrene dimers and/or styrene monomers. Styrene oligomer degrading bacteria used herein is subspecies of Vibrio Harveyi, specifically, registered with an accession number of NITE P-03589.SELECTED DRAWING: None 【課題】海洋・湖沼・河川等に蓄積している三量体以上のスチレンオリゴマーとりわけスチレントリマーをスチレンダイマー又はスチレンモノマーに分解するスチレンオリゴマー分解方法、及びその方法に使用されるスチレンオリゴマー分解性細菌を提供する。【解決手段】スチレンオリゴマー分解方法は、海洋細菌を含む懸濁液と混合することにより、３量体以上のスチレンオリゴマーを含む汚染水中の前記スチレンオリゴマーを、スチレンダイマー及び／又はスチレンモノマーに分解するというものである。スチレンオリゴマー分解性細菌が、Vibrio属Harveyi亜種であり、具体的には受託番号がＮＩＴＥ Ｐ－０３５８９であるものである。【選択図】なし
