|Results||Conclusions||Sources of Error||Applications||Acknowledgements||Bibliography||Glossary|
Absorbance: A measure of the amount of light which passes through a colored liquid or solid.
Agar: A gelatin like substance used as a culture medium for microbiological work.
Ames Test: A biological assay that finds the mutagenic potential of chemical compounds.
Antioxidant: A chemical that prevent oxidation of other chemicals.
Assay: A procedure where a property of a system or object is measured.
Autoclave: A pressurized heating device used to obtain sterile media or destroy microbially contaminated material.
Bacteria: Single celled microorganisms.
Biomolecule: A chemical compound that naturally occurs in living organisms.
Carcinogen: A substance that can cause cancer.
Centrifuge: A mechanical device that rotates an object at high speeds.
DNA: Short for deoxyribonucleic acid, DNA carries and transfers the genetic information in most organisms.
Free radical: Molecules made of oxygen that result in cell damage.
Hardwood: A deciduous or flowering tree.
Incubator: A controlled environment system which is used to keep a bacterial culture at a set temperature for a certain amount of time.
Microbe: A microorganism.
Mutagen: A substance that changes the genetic information of an organism. Substances that are mutagenic are also carcinogenic.
Pathogenic: A biological substance that can cause disease or illness.
Polyphenol: A type of antioxidant characterized by the presence of several phenol functional groups.
RPM: Short for rotations per minute.
Sodium Azide: A highly toxic chemical consisting of one sodium and three nitrogen atoms.
Softwood: A coniferous tree.
Spectrophotometer: An analytical device that can measure the absorbance of light at certain wavelengths.
Vacuum Evaporator: A device that can evaporate solvents at lower temperature with the aid of reduced pressure.
