Morphological Characteristics, Yield Performance, and Medicinal Value of Some Lingzhi Mushroom (Ganoderma lucidum) Strains Cultivated in Tam Dao, Vietnam

Abstract

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 (0.33 mg g-1) and ganoderic acid (2.38 mg g-1) were determined in strain GA3. However, the highest ganodermanontriol content was detected in the strain GA1 with 0.3 mg g-1.

Optimization of mycelial growth and cultivation of wild Ganoderma sinense

“…7B ). Under artificial cultural conditions, G. lucidum forms primordia after inoculation for 43–48 days (Ngo et al, 2019 ). Therefore, the cropping cycle of G. sinense was similar to that of G. lucidum .…”

“…Due to the abundance of available agro-industrial waste and human resources, there are good prospects for growing Ganoderma in Vietnam. The Lingzhi mushroom cultivation industry improves sustainable rural development in Vietnam (Ngo et al, 2019 ). Various methods such as log cultivation, sawdust cultivation, and substituted cultivation have been developed to cultivate Lingzhi mushrooms (Zhou et al, 2012 ), with sawdust, corncobs, cottonseed husk, and bagasse being the primary substrates (Zhou, 2017 ).…”

Cultural characteristics and cordycepin production of some Cordyceps militaris strains under artificial cultivation conditions

“…Mycelial growth, period of substrate colonization, period of primordia formation, number of stromata, and length of stroma were measured as described previously by Ngo et al (2019). The mycelial growth rate was calculated using the formula:…”
