growth of thread like structures along with the gradual spoilage of tomato can be observed when a cut tomato is kept aside for 4 days interpret the causes for the change
Answers
There is a gradual spoilage of tomato when kept aside for four days. The causes for such changes are:
1) Moisture is the cause of growth of microbes. Since, tomato has about 80 percent moisture and
2) a very mildly acidic pH, it is suitable for growth of many microbes,esp bacteria, like Azospirillum.
3) These bacteria and fungi generate polysaccharides that is visible to us as a film. This film enables microorganisms to survive properly by forming their colonies.
Answer:
"These kinds of growth is observed in cut tomatoes because the open surface provides a suitable ecosystem for the growth of the pathogens like Salmonella.
The pH and water activity of tomatoes provide the right nutrient and favorable growing conditions to these pathogens which starts secreting polysaccharide fibres when they grow. This results in the formation of a threadlike structure that we on the cut tomatoes.
