用深层培养或深层发酵(Submerged ferme-ntation或Submerged culture)法生产虫草、银耳、云芝、猴头和香菇等真菌药物的技术,在国内外已受到普遍重视。这是由于深层培养具有菌种生长周期短、成本低、菌龄齐、接种方便等优越性。 The technology of producing fungal drugs such as Cordyceps, Tremella, Yunzhi, Hericium eriniae and Mushroom by deep culture or submerged fermentation (Submerged ferme-ntation or Submerged culture) has received universal attention both at home and abroad. This is due to the deep culture of bacteria with a short growth cycle, low cost, the age of germs, inoculation convenience and other advantages.
