MICROORGANISMS FROM OUR SURROUNDINGS

WORKING CONCEPTS

The workshop allows a first contact with the microorganisms that can be grown by collecting samples from our environment. In order to be able to experience several basic concepts in microbiology, the following aspects will be address: the abundance and ubiquity of microorganisms, the diversity of morphologies, their microscopic size and the ability to modify the chemical and physical conditions of their environment through metabolic activity.

RELATED RESEARCH LINES

Different concepts and/or operations (manipulations) related to microorganisms are studied in the workshop. Specifically, the concepts of diversity and ubiquity are pillars of knowledge and often objects of study in the area of knowledge of microbial ecology. This is the general line of research that is carried out by the Microbiology lab from the Faculty of Sciences, Molecular Microbial Ecology Group (gEMM) from the Institute of Aquatic Ecology. The group develops research in the framework of basic science, and sometimes other applied aspects, where the diversity and the abundance of groups of microorganisms present in microbial communities is a key concept to understanding aspects of dynamics, and impact of these activities on biogeochemical cycles.
