This study was carried out to compare the growth characteristics, biological activities, β-glucan contents, sugar contents, and amino acid contents of 14 strains of Ganoderma spp. Among the 14 strains of Ganoderma spp., KMCC02960 (G. meredithae) and KMCC02932 (G. tropicum) showed excellent growth characteristics such as those with respect to the size and yield of fruiting bodies. The highest 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity was observed in KMCC02932 (G. tropicum). The nitrite scavenging activities of KMCC02824 (G. lucidum) and KMCC02852 (G. neo-japonicum) were higher than those of the other strains. The total polyphenol contents of the extracts from KMCC02824 (G. lucidum) and KMCC02852 (G. neo-japonicum) were higher than those of the other strains. KMCC03018 (G. lingzhi) showed the highest β-glucan content of 33.4%. In an analysis of the 4 types of monosaccharides, 2 types of disaccharides, and 4 types of sugar alcohols, only KMCC02996 (G. weberianum) and KMCC03018 (G. lingzhi) were commonly detected out of the 14 strains of Ganoderma spp. Eighteen amino acids, including eight essential amino acids, were identified: the highest total amino acids and total essential amino acids were found in KMCC02932 (G. tropicum), which had the highest levels of tyrosine and phenylalanine. Although the contents of amino acids differed by strain, cysteine, tyrosine, and phenylalanine were the most abundant amino acids in the analyzed extracts.
