项目摘要
1603741Goodey, NinaThe proposed work leverages a recent key discovery, the existence of highly functional contaminated soils, that is, where bacterial communities have adapted to the contaminants. Liberty State Park, a brownfield site in Northern New Jersey, is one example. Understanding the underlying science of enhanced biochemical function within a contaminated site is an essential step in maximizing restoration potential. The goal of this project is to better understand the high enzymatic activity which has developed and apply this knowledge to optimize functional soil treatment and inform engineering solutions in a cost effective, sustainable manner First, finding the mechanistic basis for the high enzymatic activities will be a novel and exciting contribution to ecological engineering with far reaching implications for the restoration of contaminated sites. Second, the proposed experiments will use a factorial design to determine whether: 1. the abiotic properties of the soil itself, or, 2. the microbial communities of the soils are more important to improved function. Third, this work employs targeted microbial communities originating from contaminated, undisturbed soils, in soil restoration. Measurements of extracellular enzyme activity serve as a proxy for overall soil health and function. The specific objectives of this project are: 1. Elucidate the factors driving enzymatic activity in contaminated soil by studying contaminated soils with unusually high enzyme activity in comparison to less functional, contaminated soils, and, 2. Determine the ability of microbial inocula to improve the functionality of contaminated, low functioning soils, and characterize the time course of functional transformation. Understanding the mechanisms behind the unusually high enzymatic activities will guide efforts to find functional and metal-resistant microbial communities. This will facilitate soil seeding and have direct applications to a highly cost-effective approach in restoration ecology and phytoremediation. The findings of this research and the predictive model will inform practitioners and engineers about successful microbial community compositions and time to functional transformation. The PIs will use the opportunity to extend their mentorship and expertise in training to the Liberty Science Center, situated next to Liberty State Park. As part of this grant, the PIs will work with education colleagues at the Science Center to develop workshops and outreach activities for student visitors.
1603741Goodey, Nina 拟议的工作利用了最近的一项重要发现,即存在高度功能性污染土壤,即细菌群落已经适应了污染物。新泽西州北部的一处棕地——自由州立公园就是一个例子。了解污染场地内增强生化功能的基础科学是最大限度地发挥恢复潜力的重要一步。该项目的目标是更好地了解已开发的高酶活性,并应用这些知识来优化功能性土壤处理,并以成本有效、可持续的方式为工程解决方案提供信息。首先,找到高酶活性的机制基础将是对生态工程的新颖且令人兴奋的贡献,对污染场地的恢复具有深远的影响。其次,拟议的实验将使用因子设计来确定:1.土壤本身的非生物特性,或者2.土壤的微生物群落对于改善功能更重要。第三,这项工作在土壤修复中采用了源自受污染、未受干扰土壤的目标微生物群落。细胞外酶活性的测量可作为整体土壤健康和功能的代表。该项目的具体目标是: 1. 通过研究酶活性异常高的受污染土壤(与功能较差的受污染土壤相比),阐明驱动受污染土壤中酶活性的因素;2. 确定微生物接种物改善受污染、低功能土壤功能的能力,并描述功能转化的时间过程。了解异常高的酶活性背后的机制将指导寻找功能性和金属抗性微生物群落的努力。这将有利于土壤播种,并可直接应用于恢复生态和植物修复中极具成本效益的方法。这项研究的结果和预测模型将为从业者和工程师提供有关成功的微生物群落组成和功能转化时间的信息。 PI 将利用这个机会将他们的指导和培训专业知识扩展到位于自由州立公园旁边的自由科学中心。作为这笔赠款的一部分,PI 将与科学中心的教育同事合作,为学生参观者举办研讨会和外展活动。
