Why do raw household ingredients such as granulated sugar and cooking oils never go bad in normal conditions? Extrinsic factors (room temperature) These foods have a very low Aw ph of these ingredients is too low to support spoilage organisms They do spoil
Which of the following is not a matching pair?a) Potable water—presence of pathogensb) High BOD—high organic contentc) Stabilized sludge—fertilizerd) Primary treatment—removal of material that settlese) Bulking—growth of filamentous bacteria
If high temperatures are most effective at killing microbes, what statement correctly explains why some food products are treated with temperatures below the boiling point of water? Extremely high temperatures would destroy the food's nutritional value. Extremely high temperatures would significantly lower the food's shelf life. Extremely high temperatures can destroy the food's desirable characteristics. Extremely high temperatures promote the growth of some microbes.
Which of the following treatments of sewage involves the use of anaerobic bacteria?A. Primary sedimentation tanksB. Aeration tanks in secondary treatmentC. Settling tanks in secondary treatmentD. Flat plate collectorE. Sludge digester
Imagine yourself being assigned to a very poor, remote village to educate the people about sanitation and microbial control. What method of microbial destruction or microbe population control will you teach them in order to kill/destroy the microorganisms that may be found in: 1. the gallon of pond water collected for drinking
What statement correctly explains why moist-heat is more effective than dry-heat for sterilization purposes? The microbe's molecules are resistant to alteration in the absence of water. Dry heat will always be a lower temperature than moist heat. Dry heat dehydrates the microbes, and dehydration is a method of preserving microbes. Water is a good conductor of heat.
The soil bacterium Azotobacter can be enriched from soil using liquid media, which must contain the following Mannitol Nitrate (NO3-) Amino Acids Ammonia (NH4+) All the above
Microorganism growth in complex natural environments such as soils and waters can be utilized to carry out environmental management processes. Give one term for the process you would use to cleanse a marine oil spill and discuss at least 3 types thereof. Outline factors that would facilitate the success of the process you mentioned on 1. Discuss the use of indicator organisms in testing the quality of drinking water.
Which of the following prevented an aerotolerant anaerobic, mesophilic and halophilic bacterium from contaminating your home aquarium? the water was at 37ºC you placed a high amount of glucose into the aquarium you placed several pennies in the aquarium you were using a .45 um filtering unit you placed carbon dioxide instead of oxygen into the aquarium
Desiccation, a time-honored method of preserving food, is effective because the water content is too low to support metabolic function. freezing step of the process kills microbes. salt concentration is too low to support metabolic function. heat of the process kills microbes. UV light used in the process of sun drying penetrates effectively.
Ted heats some food just to boiling, and stores some of it immediately in a container which he places in the refrigerator. A week later he takes the food out and finds it has spoiled. The microbes that spoiled the food are probably ________ organisms. thermophilic hyperthermophilic mesophilic psychrophilic. thermoduric
