Abstract:
Morchella is one of the most famous rare edible and medicinal fungi over the world. Highly nutritious and immature cultivation techniques led to the high price and the markets have remained tight. The pathogenic bacteria were serious in artificial cultivation of Morchella that affected the growth and yield of Morchella. Isolation of pathogenic bacteria and metabolites were investigated in order to improve the artificial cultivation technology. The isolated strain (YDJZ-01-01C) was identified by Gram staining and sequence of 16S rDNA. Structures of metabolites were confirmed based on NMR spectra and literatures. However, the main products were uracil and thymine that considered as important intermediate of anti-tumor 5-fluorouracil. Interestingly, a new synthetic pathway for preparation of uracil by microorganism was found except for chemical synthesis. The new preparation pathway provided mild, green, sustainable and environment friendly method to produce uracil that meets the needs of modern chemistry.
Insights
Researchers isolated bacteria from rare edible Morchella mushrooms, discovering a new microbial pathway for producing uracil, a key anti-tumor drug intermediate. This offers a sustainable alternative to chemical synthesis for pharmaceutical production.
Area of Science:
- Mycology
- Microbiology
- Biotechnology
Background:
- Morchella mushrooms are prized edible and medicinal fungi, but cultivation is hampered by pathogenic bacteria, leading to high prices and market scarcity.
- Improving artificial cultivation of Morchella is crucial for meeting market demand and reducing costs.
- Pathogenic bacteria pose a significant threat to Morchella yield and growth in artificial cultivation settings.
Purpose of the Study:
- To isolate and identify pathogenic bacteria affecting Morchella cultivation.

- To explore novel microbial pathways for producing valuable chemical compounds.
Main Methods:
- Bacterial isolation from Morchella samples.
- Identification of the bacterial strain (YDJZ-01-01C) using Gram staining and 16S rDNA sequencing.
- Structural elucidation of metabolites via Nuclear Magnetic Resonance (NMR) spectroscopy and literature comparison.
Main Results:
- A specific bacterial strain (YDJZ-01-01C) was isolated and identified.
- The primary metabolites produced were uracil and thymine.
- A novel biosynthetic pathway for uracil production by the microorganism was discovered, distinct from traditional chemical synthesis.
Conclusions:
- The identified bacterial strain offers a new, eco-friendly method for uracil production.
