Ecology Lab Report Simulating the Environment with a Winogradsky Column Louise Manangan, Katrina Olivas, Trisha Pagtakhan, Marian Pangilinan, Edward Paz Department of Biological Sciences, College of Science Abstract The Winogradsky column is a method to bring otherwise inaccessible communities into the lab. It re-creates the natural environments for bacterial growth, creating an ideal environment to research various nutrient cycles. Saturated, enriched dirt is taken and supplemented by the egg yolks and sealed off. The bacterial growth responds in patterns, or "zones", reflecting the substrate and aerobic concentrations. The prokaryotic bacteria and archaea exhibit an astonishingmetabolic diversity, which far exceeds that of animals, plants, fungi and other higher organisms. The prokaryotes literally keep our biological world turning by recycling all the mineral elements necessary for life support. The Winogradsky column- illustrates how different microorganisms perform their interdependent roles: the activities of one organism enable another to grow, and vice-versa. Introduction Microbial communities are found in pond mud, and these organisms are capable of producing metabolic by-products that are required for the survival of other organisms within the environment. By using the Winogradsky column, these products can be studied, and the interdependent relationship of the microorganisms can be observed. This column can act as a replica of the microbial environment. The Winogradsky column is a miniature, self-contained ecosystem which models ecological conditions in varying ways. It was invented by the Russian bacteriologist Sergei N. Winogradsky in 1880. The column is composed of a transparent cylindrical container which is filled with a few substrates (ex. Soil/mud) and marine or freshwater. The column is usually covered to prevent evaporation. Illumination (sunlight) is provided to promote the growth of Biology 203L EXPT 2 PAGE 18...
