Hydrocarbon-Degrading Bacteria and Paraffin from Polluted Seashores 9 Years after the Nakhodka Oil Spill in the Sea of Japan

引用

Acta Geologica Sinica(English Edition) 2006年第3期80卷 432-440页

作者： Kazue tazaki Hiroaki WATANABE Siti Khodijah CHAERUN Koichi SHIRAKI Ryuji ASADA Graduate School of Natural Science and Technology Kanazawa University KakumaKanazawaIshikawa 920-1192Japan School of Life Sciences and Technology Institute of Technology Bandung Ganesa 10Bandung 40132Indonesia

Pollution of petroleum hydrocarbons, in particular oil spills, has attracted much attention in the past and recent decades. Oil spills influence natural microbial community, and physical and chemical properties of the affected sites. The biodegradation of hydrocarbons by microorganisms is one of the primary ways by which oil spill is eliminated from contaminated sites. One such spill was that of the Russian tanker the Nakhodka that spilled heavy oil into the Sea of Japan on January 2, 1997. The impact of the Nakhodka oil spill resulted in a viscous sticky fluid fouling the shores and affected natural ecosystems. This paper describes the weathering of hydrocarbon-degrading bacteria （genus Pseudomonas） and crystallized organic compounds from the Nakhodka oil spill-polluted seashores after nine years. The Nakhodka oil has hardened and formed crust of crystalline paraffin wax as shown by XRD analysis （0.422, 0.377, and 0.250 nm d-spacing） in association with graphite and calcite after 9 years of bioremediation. Anaerobic reverse side of the oil crust contained numerous coccus typed bacteria associated with halite. The finding of hydrocarbon-degrading bacteria and paraffin wax in the oil crust may have a significant effect on the weathering processes of the Nakhodka oil spill during the 9- year bioremediation.

在日本Ishikawa Prefecture的Kanazawa大学进行了为期8个月的排水池培养实验,利用特征水和营养元素的基本因素对Sinohyliopsis schlegeli贝壳珍珠质所记录的环境变化进行观察。在2007年5月份到11月份之间,每个月向贝壳珍珠质注入四环素作为指示剂。定期测量水质,诸如pH、氧化还原势、电导率、溶解氧以及水温,通过过滤法除掉水中悬浮固体并进行光学显微镜和荧光X射线分析以及扫描电镜-能量色散X射线观察(SEM-EDX)。对贝壳珍珠质的X射线荧光化学分析表明那些富含四环素的层对应高含量的Si、Mn、Fe和Sr离子。氧化还原势和溶解氧分析都证明在珍珠质中存在层。排水池中悬浮物质主要由Si、Mn和Fe元素组成,这与2007年夏季贝壳珍珠层的生物固定化中所涉及的元素一致。SEM-EDX分析证明离子来自Siderocapsa sp.和Gallionella ferruginea硅藻的胃部。冬季几乎没有发生离子的生物固定化。结果表明在层化的贝壳珍珠质中存在元素的固定化,Sinohyliopsis schlegeli在夏季以离子为食来生长珍珠质。具有这些生物氧化物的Sinohyliopsis schlegeli可能对自然界水体中重金属的清除有一定的贡献。
