This Concept Map, created with IHMC CmapTools, has information related to: LAB 18 - USING PHYSICAL AGENTS TO CONTROL MICROORGANISMS, pasteurization description The mild heating of milk and other materials to kill particular spoilage organisms or pathogens., Using physical agents (anything not chemical) to control microbes. definitions sterilization, temperature types high temperature, osmotic pressure effect usually static in action, Hot air sterilization description Ovens used to sterilize inert materials like glass, metal, oils, and powders., boiling description 100°C. This temperature will not kill endospores., Using physical agents (anything not chemical) to control microbes. physical agent dessication, high temperature types moist heat, radiation types gamma radiation, antibiotic definition A metabolic product produced by one microorganism that inhibits or kills other microorganisms., Using physical agents (anything not chemical) to control microbes. physical agent osmotic pressure, dry heat examples Hot air sterilization, chemotherapeutic antimicrobial chemical definition Synthetic chemicals that can be used therapeutically., Using physical agents (anything not chemical) to control microbes. definitions static, low temperature action Inhibits microbial growth by slowing down microbial metabolism., dry heat action Kills microorganisms through a process of protein oxidation, Using physical agents (anything not chemical) to control microbes. physical agent temperature, Causes adjacent thymine bases on the same strand of DNA to covalently bond to one another (form thymine-thymine dimers). effect Causes deletion mutations., disinfectant definition An agents used to disinfect inanimate objects but generally to toxic to use on human tissues., radiation types ultraviolet radiation
