Development of Ling-zhi Industry in China – Emanated from the Artificial Cultivation in the Institute of Microbiology, Chinese Academy of Sciences (IMCAS)

Summary

This research traces the development of the Ling-zhi (Ganoderma) mushroom industry in China, from traditional medicine to modern commercial production. Scientists at IMCAS made breakthrough discoveries in cultivation techniques that transformed Ling-zhi from a rare wild mushroom into a commercially viable medicinal product. The research has significant everyday impacts including: • Making previously rare and expensive medicinal mushrooms widely available to consumers • Creating new healthcare products that help with various conditions from sleep to immune function • Providing economic opportunities for over 200,000 farmers in China • Developing sustainable cultivation methods using agricultural waste materials • Establishing quality standards for safe medicinal mushroom products

Background

Ling-zhi (Ganoderma) has been used as a medicinal mushroom in traditional Chinese medicine for over 2000 years. It was regarded as a magic herb called xian-cao, rui-cao, or rui-zhi in ancient China, representing good luck and happiness. The fungus was first documented in Shen Nong Materia Medica and has been extensively studied for its medicinal properties.

Objective

This review aims to summarize the history of research on Ling-zhi at the Institute of Microbiology, Chinese Academy of Sciences (IMCAS) and its role in developing the Ling-zhi industry in China. The paper covers the progression from initial resource surveys and taxonomy studies to successful artificial cultivation and modern industrial applications.

Results

IMCAS scientists achieved several key breakthroughs, including the first successful artificial cultivation of Ling-zhi fruiting bodies in China in the late 1960s. They identified critical factors like humidity requirements for fruiting body formation. The research led to widespread cultivation across China and Asia. The industry now produces over 110,000 tons annually with sales reaching US$2.5 billion. Over 780 Ling-zhi products are available in markets, including nutraceuticals and pharmaceuticals.

Conclusion

The research conducted at IMCAS has provided essential support for developing the Ling-zhi industry in China. However, challenges remain, including the need for systematic taxonomic research, standardized cultivation technologies, optimized fermentation techniques, and improved product quality control. The industry still faces issues with product homogeneity, lack of high value-added products, quality inconsistencies, and high prices.
