BIOL 2210 Study Guide - Quiz Guide: Coulter Counter, Facultative Anaerobic Organism, Colony-Forming Unit
Document Summary
Aerotolerant anaerobes - don"t use oxygen, but aren"t killed upon exposure. Facultative anaerobes - can grow in environments with or without oxgygen, and can switch their metabolism. Selective media - encourages bacterial growth of a particular species of bacteria, and suppresses growth of others. Differential media - contains an ingredient that causes observable changes in the medium when a biochemical reaction occurs (color or ph change). Direct measurements: coulter counter (electronic counter, filtration, quebec colony counter (plate count, direct microscopic count. Total count measurements: coulter counter, turbidity, direct microscopic count. Viable count measurements : filtration, quebec colony counter. Human pathogens typically classified as mesophilic (body temperature) and neutrophils (ph - neutral). If bacteria lack a spindle fiber apparatus, how does the cell ensure the. Chromosome attaches to the plasma membrane, then divides into two. T or f: bacterial cells go through the typical phases of mitosis/meiosis. That is seen in eukaryotic cells; bacteria undergo prophase, metaphase,
