1.The bacteria under study thrives at the alveolar ducts in the lungs causing respiratory disease. 2.In the experiment, the agar plate containing an axenic culture was originally incubated inside a candle jar for one day and then transferred to an oxygen-rich incubator for another day. Findings: the microbial growth persisted and stayed the same regardless of the specific type of incubation employed. 3.A microorganism that can survive pickling and refrigeration was discovered when a tightly-sealed jar of pickles grew several colonies despite following the correct recipe, tight closure seal, and proper refrigeration. 4.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

4.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.
5. There happens to be an outbreak of diarrhea caused by a bacteria in a nearby town. Upon investigation, it was found that people who are infected all swam in the river containing brackish water. A photosynthetic bacteria was isolated from the stool samples of patients and grown using common laboratory incubation techniques.
