Anaerobic bacteria and methanogenic archaea at municipal landfill dumping sites play a vital role in the landfill ecology, waste degradation, global warming and climate change. Although landfill works as a cheap way of solid waste management, unmanaged landfill plays a significant role in spreading pollutants and pathogens in natural ecosystems. The genera and are important groups of anaerobic microbes from a public and environmental health perspective. In the present study, we have isolated different species of and from landfill leachate and performed a comparative analysis to understand their role in landfill ecology and public health. Our data indicate that the anoxic zone of landfills acts as a breeding ground for different species of and , including pathogenic species like and and leachate, plays a crucial role in the spread of in soil and water ecosystem and acts as one of the primary sources of a cause of infection in field workers. We also reported that VITEK and MALDI-TOF/MS are not ideal ways to identify at the species level, and 16S rRNA gene sequencing should be the method of choice. In the current study, we also demonstrated that members of the genus showed better growth response on Brain Heart Infusion (BHI) and Gifu Anaerobic Medium (GAM), and they can be one of the alternatives to existing media for cultivation and physiological studies of
城市垃圾填埋场的厌氧细菌和产甲烷古菌在垃圾填埋生态、废物降解、全球变暖和气候变化中起着至关重要的作用。尽管垃圾填埋是一种廉价的固体废物管理方式,但未经管理的垃圾填埋场在自然生态系统中传播污染物和病原体方面起着重要作用。从公共和环境卫生角度来看,[具体属名]属和[具体属名]属是重要的厌氧微生物类群。在本研究中,我们从垃圾渗滤液中分离出了不同种类的[具体属名]属和[具体属名]属微生物,并进行了比较分析,以了解它们在垃圾填埋生态和公共卫生中的作用。我们的数据表明,垃圾填埋场的缺氧区是不同种类的[具体属名]属和[具体属名]属微生物的滋生地,包括诸如[具体致病种类名]属和[具体致病种类名]属等致病种类,渗滤液在土壤和水生态系统中[具体属名]属微生物的传播中起着关键作用,并且是野外工作者感染源的主要来源之一。我们还报告称,VITEK和基质辅助激光解吸电离飞行时间质谱(MALDI-TOF/MS)并非在物种水平鉴定[具体属名]属微生物的理想方法,16S rRNA基因测序应是首选方法。在当前研究中,我们还证明了[具体属名]属的成员在脑心浸液(BHI)和岐阜厌氧培养基(GAM)上表现出更好的生长反应,并且它们可以作为现有培养基的替代品之一,用于[具体属名]属微生物的培养和生理学研究
