BIOL 2320: Microbiology Lecture 2320
- Comprehensive Final Review
Questions Fully Solved.
Definition of pathogens - Answer A microorganism that causes disease
Decomposers - Answer Break down organic matter
Genetic engineering - Answer The direct manipulation of genes for practical purposes.
Biotechnology - Answer The manipulation of living organisms or their components to
produce useful products.
Characteristics of viruses - Answer -Cannot survive outside a host cell
-Can be seen only with an electron microscope
Phylogeny - Answer Evolutionary history of a species
-Family Tree
-Pedigree
Helminthes - Answer Parasitic worms or flukes
Taxonomic Hierarchy - Answer Domain, Kingdom, Phylum, Class, Order, Family, Genus,
Species
Bioremediation - Answer Use of living organisms such as prokaryotes, fungi, or plants to
detoxify polluted ecosystems.
Six I's of studying microbiology - Answer Inoculation - introduction of a sample into a
container of media to produce a culture.
Incubation - under conditions that allow groeth.
, Isolation - separating one species from another. A colony consists of one species. An isolation
technique may involve Streak plate technique: Pour plate technique or Spread plate technique.
Inspection
Information gathering
Identification
Types of microbial media - Answer Physical state media: liquid, semisolid and solid
Chemical composition: synthetic, and nonsynthetic
Functional type: general purpose, enriched, selective, differential, anaerobic, transport, assay,
enumeration.
Medium for fastidious bacteria - Answer Enriched media - contains complex organic
substances such as blood, serum, hemoglobin or special growth factors required.
Selective medium - Answer a culture medium with an ingredient that inhibits the growth of
microbes other than the one being sought
Differential medium - Answer A culture medium with an ingredient that certain
microorganisms change in a recognizable way; used to differentiate microbes based on their
metabolic traits
Medium with thioglycollic acid - Answer reducing media
Mannitol salt agar - Answer selective and differential
Resolving power - Answer a measure of the clarity of an image
Macronutrient - Answer A chemical substance that an organism must obtain in relatively
large amounts
Micronutrient - Answer vitamins and minerals
