The aim of this study was to evaluate the biological efficiency and main bioactive components of three G. lucidum strains, viz. GA1, GA2, and GA3, cultivated in Tam Dao town. The results demonstrated that all strains were capable of growing well on PDA medium supplemented with rice bran. The time required for complete colonization was 9 days. All tested strains of G. lucidum were able to adapt to climate conditions and produce fruiting bodies with satisfactory yield (13-17%), and therefore, they could be considered suitable candidates for commercial cultivation of G. lucidum in Tam Dao. No significant differences in polysaccharide content were observed among all strains. High concentrations of lucidenic N acid ( mg g-1 ) and ganoderic acid ( mg g-1 ) were determined in strain GA3. However, the highest ganodermanontriol content was detected in the strain GA1 with mg g-1 . | Nội dung Text Morphological characteristics yield performance and medicinal value of some lingzhi mushroom Ganoderma lucidum strains cultivated in Tam Dao Vietnam
