This is a proposal to study the impact of the BP oil spill in the Gulf of Mexico in April, 2010, on the bacterial community in general, and specifically on predation involving Bdellovibrio and like organisms (BALOs) and their prey bacteria.This new thrust is consistent with the general aim of an existing HBCU-RISE project which is to better understand predation by BALOs on their prey and the contributions of the predatory bacteria to bacterial mortality,and,thereby, the control of bacterial populations in aquatic systems. Microorganisms are responsible for many of the natural processes that maintain healthy aquatic and terrestial ecosystems. There is great concern that the oil deposits in Gulf waters and sediments will disrupt the microbial community and those system functions for which they are responsible.The project will monitor the changes in the bacterial community and investigate the changes on an important ecological function,which is predation. Broader Impacts:The project will engage both undergraduate and graduate students in studying the impact of the largest catastrophic oil spill event in the US.Intellectual Merit:This research will uncover new scientific data on both the impacts of oil spills on microbial communities and their functions, and in the ecological systems in general.

本课题旨在研究2010年4月墨西哥湾BP石油泄漏事件对细菌群落的总体影响，特别是对蛭弧菌及其类生物（BALOs）及其猎物细菌的捕食影响。这一新的重点与现有HBCU-RISE项目的总体目标是一致的，该项目旨在更好地了解BALOs对其猎物的捕食以及掠食性细菌对细菌死亡率的贡献，从而控制水生系统中的细菌种群。微生物对维持健康的水生和陆地生态系统的许多自然过程负有责任。人们非常担心海湾水域和沉积物中的石油沉积物会破坏微生物群落和它们所负责的系统功能。该项目将监测细菌群落的变化，并调查一项重要的生态功能的变化，即捕食。更广泛的影响：该项目将吸引本科生和研究生研究美国最大的灾难性石油泄漏事件的影响。智力价值：这项研究将揭示石油泄漏对微生物群落及其功能的影响以及总体生态系统的新的科学数据。
