Summary
This research studied harmful fungi that affect the cultivation of the edible mushroom Agrocybe aegerita. The scientists identified several types of mold that can contaminate and damage mushroom crops, with Trichoderma species being the most common culprits. Understanding these pathogens is crucial for protecting commercial mushroom production.
Impacts on everyday life:
• Helps mushroom farmers better protect their crops from harmful contamination
• Contributes to maintaining stable supplies of edible mushrooms for consumers
• Supports food security by improving commercial mushroom cultivation practices
• Aids in developing better methods to prevent crop losses in mushroom farming
• Helps keep mushroom prices stable by preventing large-scale crop failures
Background
Agrocybe aegerita is an important cultivated mushroom in Korea known for its good texture and distinctive fragrance. It can be cultivated year-round using culture bottles but is more susceptible to contamination than other mushrooms. The mushroom industry has suffered from various disease epidemics that can completely prevent mushroom production in contaminated beds.
Objective
The study aimed to identify and characterize Trichoderma species and other pathogens present in fruiting bodies and substrates of commercial A. aegerita based on morphological and molecular characteristics. This research was needed because the occurrence and diversity of Trichoderma species associated with A. aegerita had not been well studied previously.
Results
Of 29 total isolates, 26 were identified as Trichoderma species and three were identified as Aspergillus, Mucor, and Penicillium species. The Trichoderma isolates were divided into four taxa: T. harzianum (16 isolates, 55.2%), T. pleuroticola (6 isolates, 20.7%), T. longibrachiatum (2 isolates), and T. atroviride (2 isolates). Each species showed distinct morphological characteristics in terms of colony appearance, spore size and shape, and growth patterns.
Conclusion
The study successfully identified and characterized multiple pathogenic fungi affecting A. aegerita cultivation, with Trichoderma species being the predominant pathogens. T. harzianum was found to be the most common species, followed by T. pleuroticola. The findings provide important insights into mushroom pathogens that can help inform disease management strategies in commercial mushroom cultivation.
