BSc Biomedical Sciences with Industrial/Professional Experience / Course details

Year of entry: 2021

Course unit details:
Geomicrobiology

Unit code EART30831
Credit rating 10
Unit level Level 6
Teaching period(s) Semester 1
Offered by Department of Earth and Environmental Sciences
Available as a free choice unit? Yes

Overview

The course will be delivered by Prof Lloyd, augmented with invited guest lectures as appropriate covering emerging “hot topics” in the area. Initial lectures will focus on the “microbiological basics” to make sure that all of the students on the course have the required foundations, followed by lectures (and group activities) covering fundamental elemental cycles, including an emphasis on the ways that these natural processes can be utilised in diverse areas of science of technology. These will include bioremediation, high value bionanomaterial synthesis and the safe exploitation of the subsurface.

This course unit detail provides the framework for delivery in 20/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

 

Aims

The aim of this course is to provide insight into the role that microorganisms play or have played in geological processes, covering the molecular-scale mechanisms of global bioprocesses, through to high technology biotechnological applications

 

 

Learning outcomes

On successful completion of the course, students will be able to:

  • Describe a range of techniques important for geomicrobiological research, including the techniques of microbiology, molecular biology, mineralogy and geochemistry

  • Explain how microorganisms control the chemistry of Earth (and potentially other planets)

  • Critically analyse seminal geomicrobiological papers from the peer review literature

  • Explain how natural microbiological processes can be used for applications including bioremediation and the safe exploitation of the subsurface

Week 12: Past papers and revision

 

Teaching and learning methods

 

The course typically consists of 2 hour lecture slots each week, covering 1-2 topics, with time included for discussions with the students.

The following specific topics will be included:

Techniques for geomicrobiology.

The origin of life and astrobiology.

Microbial diversity of modern Earth.

The geomicrobiology of carbon, silica, phosphorous, nitrogen, sulfur, iron, manganese, toxic trace metals and radionuclides.

Applications of geomicrobiology including bioremediation, safe geological disposal (including CO2 and radwaste) and bioenergy production.

In addition, there will be “breakout” group work and presentations on approaches for geomicrobiological sampling and analyses (e.g. for extreme environments, such as the deep subsurface, life on other planets, hydrothermal vents), and a poster session on seminal geomicrobiology papers from the scientific literature. The extreme environment group work and presentations will help the students consolidate information on key techniques used in this cross-disciplinary field, and will not be assessed for a final mark (although oral feedback will be given on the day of presentations).  The poster session will be run as a mini conference (online if necessary), and the poster presentations will carry 30% of the course marks.

There will also be a revision session towards the end of the course, where past papers from the course are discussed. The final open book assessment carries 70% of the course marks. If required, online revision tests can be provided throughout the course to help consolidate the content of the lectures.
