Benefits of technology

This patented technology allows for quick addition of nutrients like phytate or lithochloride into yeast cultures without causing excessive cellular damage that could affect their ability to produce certain types of compounds called flavonoids. By adding these substances directly onto cells grown on solid substrates instead of relying solely upon them themselves, this method results in increased yields compared with traditional methods while reducing costs associated therewith.

Problems solved by technology

The technical problem addressed by this patented text relates to finding ways to increase or decrease the content (polymer) fraction of phellsinsuccinosidiae during culturing without affecting its quality for use in medicine purposes due to their complex structure and high cost per gram produced through traditional methods.

Abstract

The invention provides a method for applying plant oil to submerged culture of a medicinal fungus phellinus igniarius and improving phellinus igniarius hypha amount. A phellinus igniarius fermentation medium is prepared according to a technique disclosed in a patent with the patent application number of 200810070224, the initial pH of the medium is controlled to be 5.5-7.5, the sterilization temperature is 115 to 121 DEG C, and the sterilization time is 30 minutes. In the initial stage of the fermentation, different types of plant oil with the concentration of 0.5 to 5 mass percent are added, including soybean oil, olive oil, rap oil and the like, a shake flask fermentation or fermentation tank fermentation process is adopted, the inoculum size is 5 to 15 percent, and the culture temperature is 24 to 28 DEG C. The method has the advantages of simple operation process and low fermentation production cost, can be used for large-scale submerged culture production process of the phellinus igniarius, and also can be used for the liquid fermentation production process of other medicinal fugi, such as lucid ganoderma, agaricus blazei and lentinus edodes.
