7.343 Sophisticated Survival Skills of Simple Microorganisms (MIT) 7.343 Sophisticated Survival Skills of Simple Microorganisms (MIT)

Description

In this course, we will discuss the microbial physiology and genetics of stress responses in aquatic ecosystems, astrobiology, bacterial pathogenesis and other environments. We will learn about classical and novel methods utilized by researchers to uncover bacterial mechanisms induced under both general and environment-specific stresses. Finally, we will compare and contrast models for bacterial stress responses to gain an understanding of distinct mechanisms of survival and of why there are differences among bacterial genera. This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly In this course, we will discuss the microbial physiology and genetics of stress responses in aquatic ecosystems, astrobiology, bacterial pathogenesis and other environments.

Effects of pollutants on the aquatic environment

Description

Effects of pollutants on the aquatic environment is a free course. It begins with an introduction to water and goes on to briefly outline the major sources of water pollution (these being sewage works, manufacturing and industrial plants, the farming and animal husbandry sectors, landfill sites and urban surface water run-off). It considers the major water pollutants and describes the effects they have on water. First published on Wed, 01 Feb 2017 as Effects of pollutants on the aquatic environment.

The three-way catalytic converter

Description

This extract is concerned primarily with the chemistry that underpins the operation of the three-way catalytic converter that is placed in the exhaust systems of motor vehicles in order to reduce the emissions of primary pollutants: carbon monoxide, oxides of nitrogen and volatile organic compounds, including hydrocarbons. Discussion of the various effects of these pollutants and the consequent introduction and refinement of ‘automotive emission regulations’ has not been included, nor is there a look forward to future research trends. These topics are covered in the original Case Study.
