The microconstituents of Ganoderma lucidum biomass (GLB) were evaluated, along with its antimicrobial and anticancer activities. Using gas chromatography-mass spectrometry analysis, 12-octadecadienoic acid (Z,Z)- and n-hexadecanoic acid with area% values of 21.0% and 11.0% were recognized in GLB. Uncooked biomass (UCB) and microwavecooked (CE) biomass of G. lucidum caused a significant inhibition of human breast cancer (MCF-7) cell line proliferation in a dose-dependent manner. The inhibition of MCF-7 cell proliferation was 27.22 ± 1.64% using 16 µg/mL of CB while it was 52.29 ± 1.09% using 16 µg/mL of UCB. The cytotoxicity test recorded low IC50 (25.63 ± 0.52 µg/mL) of UCE compared to the IC50 value (49.99 ± 0.94 µg/mL) of CB. Highest antimicrobial activities were recorded via using UCE, compared to CE against Bacillus subtilis, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Candida albicans, and Aspergillus niger. The 9,12-octadecadienoic acid (Z,Z)- and n-hexadecanoic acid were able to induce both anticancer and antibiotic-resistant properties. A key therapeutic target enzyme for evolving this resistant pathogenic activity on MCF-7 and K. pneumonia, was accessed thoroughly in silico study. The compounds described, therefore, might provide a great potential for the development of new therapeutics such as anticancer and antimicrobial agents. [ABSTRACT FROM AUTHOR]
