- Which of the microbes listed below would be most optimal to use in alcohol production? Escherichia coli Bacillus subtilis Lactobacillus Alcoholphillus O SaccharomycesWhich of the following cannot be grown in artificial media and must be grown in live animals or cells instead? Neisseria gonorrhoeae, the causative agent of gonorrhea Lactococcus lactis, a lactic acid bacterium used to produce cheddar cheese Staphylococcus aureus, a bacterium sometimes found in human nares (nostrils) Staphylococcus epidermidis, a bacterium routinely found on human skin Escherichia coli, a bacterium common in mammalian intestines 21 Treponema pallidum, the causative agent of syphilisPHBs and related compounds such as PHAs (poly-hydroxy-alkanates) are plastic-like molecules that are of great interest to industrial microbiologists. Why is there so much interest in microbially produced plastics?
- Which of the following is probably the cause of most human diseases on the skin which is salty? an acidophilic and halophilic bacterium an alkalophilic and halophilic bacterium a psychrophilic and thermophilic bacterium a mesophilic and halophilic bacterium a thermophilic and acidophilic bacteriumDay Care Center outbreak: Salmonellosis You just finished identifying the fecal contaminated food at the first restaurant when you learn there is an outbreak of Salmonella-food poisoning at a day care center, You sample food from the Center's refrigerator and are worried that the egg salad or chicken salad or peanut butter used to make sandwiches may be contaminated with Salmonella. You know Salmonella cannot ferment lactose and it can make hydrgoen sulfide. The strain associated with the outbreak cannot ferment sucrose but can ferment glucose. You isolate in pure culture bacteria from each of the suspect foods and inoculate each into TSI slants. (see results below) egg salad microbe chicken salad microbe peanut butter microbe TSI TSI TSI W FWSBacteria that are obligate intracellular pathogens of humans are considered to be Autotrophs Heterotrophs Photosynthetic Hyperthermophiles Chemolithotrophs Which of the following statements best describes the pathogenesis of Clostridium botulinum? It elaborates an exotoxin that is a lecithinase that causes tissue necrosis. It elaborates a toxin that suppresses the release of inhibitory neurotransmitters. It produces a polysaccharide capsule that inhibits phagocytosis and contributes to invasion of the central nervous system. It elaborates a toxin that inhibits the release of acetylcholine at cholinergic synapses. It produces a leukotoxin that leads to abscess formation.
- Which of the following statements regarding microbial death is FALSE? Question options: cell walls are targeted by many microbial control agents the effectiveness of an antibacterial agent is a funciton of its microbial death rate the rate at which microbes are killed is termed the microbial death rate all of these statements are TRUE few antimicrobial agents function through the disruption of protein structure under a given set of conditions, the fraction of a microbial population that dies per minute is typically constant over timeJams, jellies, preserves, honey, and other foodstuffs with a high sugar content hardly ever become contaminated by bacteria, even when the food containers are left open at room temperature.
