Recovery and/or remediation of submerged oil releases pose special challenges during all phases of emergency response because it is difficult to track and locate the subsea plume. In this study, the process of submerged oil release was realized and continually tracked for 38 days in the laboratory using simulated columns. The results indicated that LSH-7′ degradation bacteria could change the microbiological population structure of sea water, primarily reflecting the dominant species succession. Additionally, the oil under dispersant could easily promote bacterial growth. Furthermore, LSH-7′ degradation bacteria and nutrients could affect the native bacteria by promoting or restraining. To the best of our knowledge, this article is the first to report that the dispersion effect of the dispersants, the emulsification effect, and the microbial degradation of the petroleum hydrocarbon microbial degradation effect exist in a special relationship to control petroleum hydrocarbon. These findings deepen our understanding on behavior end-result and biodegradation of submerged oil.

在应急响应的所有阶段，淹没油的释放的恢复和/或补救面临特殊挑战，因为很难追踪和定位海底羽流。在这项研究中，浸没油的释放过程得以实现，并在实验室中使用模拟色谱柱连续跟踪了38天。结果表明，LSH-7'降解细菌可以改变海水的微生物种群结构，主要反映了优势种的演替。另外，在分散剂下的油可以容易地促进细菌生长。此外，LSH-7'降解细菌和营养物质可能通过促进或抑制而影响天然细菌。据我们所知，本文是第一个报道分散剂的分散效果，乳化效果，与微生物降解对石油烃的微生物降解作用存在着特殊的关系，以控制石油烃。这些发现加深了我们对水下石油行为最终结果和生物降解的理解。
