项目摘要

Tightening regulations on biosolids disposal and growing energy utilization increase the operational costs of wastewater treatment plants, and reduce the sustainability of municipal infrastructures. In response, the wastewater industry is converting from only treating wastewater for environmental protection to additionally recovering resources wasted with the water. In terms of energy content, recoverable organics and nutrients (nitrogen, phosphorus) account for ~15% of the per capita electricity consumption; accordingly, recovery will improve sustainability and reduce CO2 footprint. However, recovery using current aerobic biological processes is limited. Thus, the current program will contribute to the development of new anaerobic biological processes enabling recovery. The results will improve infrastructure efficiencies and reduce burden to tax payers.******Anaerobic processes pose challenges for Canada because many wastewater facilities operate below 12C for periods of up to 6 months. Indeed, anaerobic microbes typically have lower maximum growth rates than aerobic ones, resulting in lower process stability and capacity to meet discharge regulations at low temperatures. Additionally, municipal wastewater is relatively dilute for nutrient recovery, and biological concentration is necessary prior to physico-chemical extractions. We propose to use purple non-sulfur bacteria (PNSB) to address these challenges. Their ability to simultaneously obtain energy from light and carbon from organics provides them with higher biomass yields and faster growth rates than other anaerobes. Consequently, high biomass yields make them suitable for concentration of nutrients in biomass, and high growth rates reduce their sensitivity to colder operation temperatures. Finally, because they are the only photosynthetic organisms utilizing infrared light (>800 nm), engineers would possess powerful selection tools to control microbial communities in mixed open cultures.*******Published studies mainly focused on pure culture PNSB wastewater processes and operation at 20-35C. These conditions are inapplicable to full-scale Canadian municipal wastewater facilities; thus, significant knowledge gaps persist in developing PNSB processes. Additionally, reactor conditions need to be tightly controlled such that metabolism maximizes biomass yields instead of competing H2 and polyhydroxyalkanoate syntheses. This proposal will investigate operation conditions of non-sterile PNSB photobioreactors that are relevant to Canada for enabling implementation of wastewater resource recovery. Furthermore, control strategies for PNSB metabolism and microbial community composition will be developed by using genome-scale metabolic modeling and high-throughput metagenomic molecular tools. The program will train 2 PhD, 4 MEng and 10 undergraduate students.***
收紧有关生物固体处置和不断增长的能源利用的法规增加了废水处理厂的运营成本,并降低了市政基础设施的可持续性。作为回应,废水行业正从仅处理废水来进行环境保护,再到浪费了水的资源。在能量含量,可回收有机物和营养(氮,磷)方面,约占人均用电消耗的15%;因此,恢复将改善可持续性并减少CO2足迹。但是,使用当前有氧生物学过程的恢复有限。因此,当前的程序将有助于开发新的厌氧生物学过程,从而恢复。结果将提高基础设施效率,并减轻纳税人的负担。******厌氧流程对加拿大构成挑战,因为许多废水设施在最多6个月的时间内运行到12C以下。实际上,厌氧微生物的最大生长速率通常低于有氧生长速率,从而导致过程稳定性较低,并且在低温下满足排放法规的能力较低。此外,市政废水相对稀释以养分养分,并且在物理化学提取之前,必须使用生物学浓度。我们建议使用紫色非硫细菌(PNSB)来应对这些挑战。与其他厌氧菌相比,它们从有机物中同时从光和碳中获得能量的能力可为它们具有更高的生物质产量和更快的生长速度。因此,高生物质产量使其适合于生物量中的养分浓度,高增长率降低了其对较冷的操作温度的敏感性。最后,由于它们是利用红外光(> 800 nm)的唯一光合生物,因此工程师将拥有强大的选择工具来控制混合开放式培养物中的微生物群落。这些条件不适用于加拿大全尺寸的市政废水设施;因此,重要的知识差距在开发PNSB过程中持续存在。此外,需要严格控制反应器条件,以使代谢最大化生物量的产量,而不是竞争H2和多羟基烷烃合成。该提案将调查与加拿大有关以实施废水资源恢复的非紧密PNSB光生反应器的运行条件。此外,将使用基因组规模的代谢建模和高通量元基因组分子工具来开发PNSB代谢和微生物社区组成的控制策略。该课程将培训2位博士学位,4名Meng和10名本科生。***
