CE 555 - Microbial Aspects of Environmental Engineering Laboratory Experiment – Winogradsky Column Objectives 1. To create a bench-scale microbial ecosystem in which complex microbial communities are cultivated. 2. To gain appreciation for the diversity of methods microorganisms use to gain energy and how those metabolic processes affect the surrounding environment, and, thus, determine microbial community composition and succession. Introduction Sergei Winogradsky (1856-1953) who, along with Martinus Willem Beijerinck (1851-1931), developed the technique and was a pioneering Russian microbiologist who worked in the late 1800’s and early 1900’s, when microbiology was still a fledgling science. At a time when microbiological methods barely existed and most microbiologists focused on the ‘germ- theory’ of disease, the isolation of individual microbes and the characterization of ‘domesticated’ laboratory strains, Winogradsky focused on environmental microbiology and developed techniques for cultivating and studying complex microbial communities (such as the Winogradsky column). In so doing, he made great advances in our understanding of environmental microbiology, microbial diversity, microbial physiology, microbial autotrophy (the ability to obtain energy from non-organic substances) and environmental nutrient cycling (particularly sulfur and nitrogen
