Antrodia cinnamomea Culturing with Composite Substrate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cultivation methods for Antrodia cinnamomea, such as basswood, solid, and liquid fermentation methods, are time-consuming and inefficient in producing fruiting bodies rich in triterpenoids, limiting industrial scalability and effectiveness.
Innovation Solution
A solid medium comprising 20-50% soybean, 30-50% coixseed, and 20-50% sorghum, with a culturing method involving static inoculation and intermittent shaking, promotes triterpenoid production by providing a supportive matrix for hyphae growth and secondary metabolism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If basswood cultivation method is used, then fruiting bodies can be obtained, but culturing time is long and cost is high
Solution Approach 1:
The patent changes the substrate parameters from traditional basswood to a composite medium containing corn cob powder, soybean meal, and other agricultural byproducts. This parameter change in substrate composition enables significantly reduced culturing time while maintaining fruiting body production capability
Solution Approach 2:
The invention replaces expensive basswood with cheap agricultural byproducts such as corn cob powder and soybean meal. These inexpensive materials serve as effective substrates, reducing both material cost and culturing time without compromising the ability to produce fruiting bodies
2Reliability
If solid cultivation method is used, then fruiting bodies can be obtained, but triterpenoid content is low
Solution Approach 1:
The patent uses a composite solid medium combining multiple materials (corn cob powder, soybean meal, rice bran, etc.) that work synergistically. This composite substrate not only supports fruiting body formation but also enhances secondary metabolite production, particularly triterpenoids, addressing both contradictions simultaneously
3Productivity
If liquid fermentation method is used, then fermentation speed is fast, but triterpenoid production is limited
Solution Approach 1:
The patent employs a two-stage culturing approach: first growing mycelium rapidly on the composite solid medium, then inducing secondary metabolite production through controlled conditions. This preliminary growth phase followed by metabolite induction phase achieves both fast productivity and high triterpenoid content

AI summary
A solid medium of Antrodia cinnamomea comprises 20 to 50 wt % soybean; 30 to 50 wt % coixseed; and 20 to 50 wt % sorghum. A culturing method of Antrodia cinnamomea, comprises providing a solid medium comprising soybean, coixseed and sorghum; preparing a solution of Antrodia cinnamomea, inoculating the solution of Antrodia cinnamomea on the solid medium in a concentration of 1×103 to 1×106 cfu on per 100 g of solid medium, and statically culturing the solution of Antrodia cinnamomea on the solid medium till obtaining hyphae adhered on the solid medium; and culturing the solution of Antrodia cinnamomea by intermittent shaking in a frequency of every 5 to 7 days shaking 5 to 10 minutes, with a period of the culturing by intermittent shaking being more than 40 days.
