Analysis of Microbial Community Structure and Cultivation Performance Assessment in Tremella fuciformis Liquid...

Area of Science:

• Mycology
• Agricultural Science
• Industrial Biotechnology

Background:

• Liquid inoculum is preferred in mushroom cultivation but challenging for Tremella fuciformis due to its complex microbial community and dimorphic growth.
• Existing methods using liquefied solid spawn show inconsistent yields and microbial instability.

Purpose of the Study:

• To develop a reliable protocol for Tremella fuciformis liquid inoculum.
• To assess the practical application and performance of the developed liquid inoculum in industrial cultivation.

Main Methods:

• Initial liquefaction of solid spawn was performed.
• A novel liquid spawn was developed using pre-cultured pure mycelia of Tremella fuciformis and Annulohypoxylon stygium.
• Cultivation tests were conducted to compare the performance of the new liquid spawn against solid spawn.

Main Results:

• Standard liquefied spawn increased yield by 8.2% but showed batch-to-batch variation.
• The novel liquid spawn, using pure mycelia, resulted in a 11.1% yield improvement (608.2 g/kg dry substrate) compared to solid spawn.
• The new method ensured stable microbial communities with dominant Tremellomycetes (>50%) and consistent yields across batches.

Conclusions:

• The developed Tremella fuciformis liquid spawn protocol is reliable and effective for industrial production.
• This liquid spawn offers a stable and high-yielding alternative to traditional solid spawn, enhancing cultivation efficiency.
