The world of the cell

Prokaryotic and eukaryotic cell types - compare and contrast. Cell organelles and their functions. Basic microscopy.Biological molecules and their functions. Microbes - viruses, bacteria, and fungi. Common biological terms will be explained.

The microbial world – the good the bad and the ugly!

Microbiology for manufacturing operators – introduction to bacteria, fungi, yeast, and viruses.Microbial isolation, growth and identification. Examination of sources of microbes and biological contaminants in the environment. Personnel as sources of biological contamination. Measurement and control of microbial and biological contamination.

Microbial Methods

Assessing the type, amount and distribution of micro-organisms in working environments. Use of plate count metohds to enumerate microorganisms. Colorimetric methods for the detection of biomolecules.

Principles of Biological Control and Sterilisation

Overview of methods to reduce and or eliminate micro-organisms from environments, ingredients and products. Review of physical and chemical methods of microbial control and sterilisation methods.

Microorganisms in Industry

Fermentation, Biotechnology, Useful Microorganisms,
