MICP

• In Vitro


  Events that occur outside the body
• In Vivo


  Events that occur inside the body
• Nutrients


  Various chemical compounds that organisms use to sustain life
• Optimum Growth Temperature


  Temperature at which organisms grow best
• Minimum Growth Temperature


  Temperature below optimum at which organism ceases to grow
• Maximum Growth Temperature


  Temperature above optimum at which an organism dies
• Desiccation


  Complete drying process or removal of moisture
• Mesophiles


  • Microbes that grow best at moderate temperatures
• Psychrophiles


  • Organisms that "love" cold temperatures
• Thermophiles


  • Organisms that "love" high temperatures
• Psychrotrophs


  • A group of psychrophiles
• Moisture


  Presence of slight to moderate amount of liquid, especially water
• pH


  Hydrogen ion concentration of the solution and thus the acidity or alkalinity of a solution
• Psychroduric Organisms


  • Microorganisms that prefer warmer temperatures but can tolerate or endure very cold temperatures and can be preserved in the frozen state
• Acidophiles


  • They prefer acidic environments, whereas alkaliphiles prefer environments that are alkaline
• Vibrio cholerae is the only human pathogen that grows well above pH 8
• Alkaliphiles


  • Microbes that prefer an alkaline environment
• Osmotic Pressure


  A physical method that inhibits growth by limiting availability of water for metabolic activity
• Hypertonic


  When the concentration of solutes in the environment outside of a cell is greater than the concentration of solutes inside the cell
• Osmosis


  Movement of a solvent (e.g.,water), through a permeable membrane, from a solution having a lower concentration of solute to a solution having a higher concentration of solute
• Crenation


  Shrinkage of cells
• Hypotonic


  When the concentration of the solutes outside the cell is less than the concentration of the solutes inside the cell
• Plasmolysis


  Condition when the cell membrane and cytoplasm shrink away from the cell wall
• Hemolysis


  Bursting of cells
• Plasmoptysis


  Escape of cytoplasm from the cell due to great pressure and the cell ruptures
• Isotonic


  When the concentration of solutes outside a cell equals the concentration of solutes inside the cell
• Halophiles


  • Microorganisms that prefer salty environments
• Haloduric Organisms


  • Organisms that do not prefer to live in a salty environment but capable of surviving there
• Piezophiles


  • Microorganisms that thrive is an environment with extremely high atmospheric pressure
• Fungi are cellular eukaryotic microorganisms that prefer acidic environments
• Barometric Pressure


  Pressure within the atmosphere of the Earth
• Microaerophiles


  • Microorganisms that live in environments containing reduced concentrations of oxygen (around 5% oxygen)
• Capnophiles


  • Microorganisms that grow best in environments rich in carbon dioxide
• Bacterial Growth


  Proliferation or multiplication of bacteria
• Generation Time


  Time it takes for one cell to become two cells by binary fission
• Fastidious Organisms


  • Microorganisms that are difficult to grow in the laboratory.
• Artificial/Synthetic Media


  Media used in microbiology laboratories to culture bacteria
• Chemically Defined Medium


  Media in which all the ingredients are known
• Complex Medium


  Media in which the exact contents are not known
• Enriched Medium


  Broth or solid medium containing a rich supply of special nutrients that promotes the growth of fastidious organisms
