Beta-lactamase-producing bacteria (BLPB) may have an important clinical role in infections. These organisms can be pathogenic in causing the infection as well as have an indirect effect through their ability to produce the enzyme BL into their environment.
If you turn the dial to number 0, that effectively turns the fridge off. Setting the dial to 9, the refrigerator will be working at its max capability. Your personal temperature setting will depend on how much food is kept in the refrigerator. If your fridge is packed with food, it needs to be on a higher number setting to maintain a low (colder) temperature. The temperature controller dial or slider on your refrigerator is a thermostat. It kicks the compressor on when the refrigerator is not cold enough.
If you cannot locate the wattage, calculate it by finding the current draw (in amperes) and multiplying that by the refrigerator's voltage. In most cases, the amperes are stamped on the refrigerator in place of the wattage, and most refrigerators use 120-240 volts. It is important to keep in mind that even when a refrigerator is turned off, it continues to draw a small amount of power, called a phantom load. Learn more about Refrigerators & Freezers
