Chapter 9, Problem 1CM
Summary Introduction
To fill:
The applications of moist heat for controlling the microorganisms.
Concept introduction:
The term aseptic condition refers to the completely devoid of microbes. The sterilization, disinfectant, sanitization, and radiation are some of the physical and chemical methods to get rid of microbes. Sterilization by heat is one of the key factors used for eradicating the microbes. The heat has the capability to denature the microbe’s proteins, alter its cell wall, and cause irreversible damages to its

Classify the bacteria that is most likely involved in each situation provided according to their classification (as to microbial growth requirements). Check the correct answers from the choices.
1. The bacteria under study thrives at the alveolar ducts in the lungs causing respiratory disease.
Obligate aerobe
Obligate anaerobe
Microaerophile
Aerotolerant anaerobe
Mesophile
Thermophiles
2. A microorganism that can survive pickling and refrigeration was discovered when a jar of pickles grew several colonies despite following the correct recipe, tight closure seal, and proper refrigeration.
Psychrophile
Psychrotroph
Neutrophile
Acidophile
Obligate aerobe
Microaerophile
3. The spoiled bottle of wine that was stored at standard room temperature for several months eventually gave off a vinegar-like taste and odor. Spoilage was found to be due to the leaky bottle closure leading to bacterial contamination.
