The landscape of this Resource and Environmental Microbiology team primarily covers the fundamental and applied research on the microorganisms responsible for the cycling of various important materials. To better understand the interactions between microbial individuals, populations and communities as well as the corresponding interactive mechanisms, techniques of molecular ecology and molecular biology have been broadly employed to study the ecology, metabolic activity and signaling regulation of microorganisms responsible for the geographic cycling of carbon and nitrogen. Meanwhile, based on the notion of transforming waste to reusable resources, biotechnological techniques have been applied for the collective and comprehensive treatment of contaminations both at point and non-point sources.
