The laboratory experiment to determine the fungi associated with spoilage of tomatoes would typically be conducted by a microbiologist or a food scientist. These professionals would have the expertise and knowledge to properly collect samples, isolate and identify the fungi present, and analyze the results to determine the specific species responsible for the spoilage. The experiment would involve various techniques such as culturing, microscopy, and molecular analysis to accurately identify the fungi present in the spoiled tomatoes.

Title: Determination of Fungi Associated With Spoilage of Tomatoes
Objective:
To identify and characterize the fungal species responsible for the spoilage of tomatoes.
Materials:
- Ripe tomatoes
- Sterile containers
- Sterile nutrient agar
- Sterile selective media (e.g., potato dextrose agar, malt extract agar)
- Microscope
- Slides and coverslips
- Fungal identification keys
Procedure:
1. Collection of Samples:
- Collect ripe tomatoes from a local market or grocery store.
- Select tomatoes with visible signs of spoilage (e.g., soft spots, lesions, discoloration).
2. Sterilization of Containers:
- Sterilize sterile containers by autoclaving at 121°C for 15 minutes.
3. Preparation of Nutrient Agar:
- Prepare sterile nutrient agar plates according to the manufacturer's instructions.
4. Isolation of Fungi:
- Cut small pieces of infected tomato tissue and place them aseptically onto sterile nutrient agar plates.
- Incubate the plates at 25°C for 5-7 days.
5. Microscopic Examination:
- Examine the plates for the presence of fungal colonies.
- Isolate individual colonies onto sterile selective media plates to obtain pure cultures.
- Prepare microscope slides from the pure cultures and stain with lactophenol cotton blue or other suitable stains.
- Observe the slides under a microscope to identify the fungal species based on their morphological characteristics (e.g., spore shape, septation, conidiophores).
6. Identification of Fungi:
- Use fungal identification keys to identify the fungal species associated with the spoiled tomatoes.
Expected Results:
- Isolation of various fungal species from the spoiled tomatoes.
- Identification of the fungal species responsible for the spoilage, based on their morphological characteristics.
Discussion:
This experiment will provide information about the fungi responsible for the spoilage of tomatoes. Understanding the identity of these fungi is crucial for developing control measures and minimizing losses during storage and transportation of tomatoes.
