REL 1000 Lecture Notes - Lecture 2: Isopropyl Alcohol, Anaerobic Organism, Obligate Aerobe
Document Summary
Compare the three reproductive strategies used by bacteria other than binary fission: binary fission, budding, filamentous. Use the terms that describe a microbe"s growth range or requirement of solute, ph, temperature, oxygen, and pressure: extremophiles, grow under harsh conditions that would kill most other organisms, halophiles, grow optimally at >0. 2 m. Describe the enzymes observed in microbes that protect them against toxic. Discuss the use of enrichment cultures in isolating microbes. Differentiate the streak plate, spread plate, and pour plate methods for isolating pure cultures: spread plate, coli beads, pour plate, take sample and pour agar on top of it, anaerobe or facultative aerobe. Compare and contrast disinfection, antisepsis, chemotherapy, and sterilization. Identify examples of each: sterilization : complete removal or destruction of all viable microorganisms used on inanimate objects (kills all, disinfection: destruction or removal of vegetative pathogens but not bacterial endospores.
