Decoding the Bioluminescent and Non-Bioluminescent Traits of <i>Panellus stipticus</i>: A Genomic and Phenotypic Perspective.

ABSTRACT: The species Panellus stipticus presents a unique situation whereby some geographic strains are bioluminescent while others are not. This study investigates the factors affecting the bioluminescence of P. stipticus, focusing on culture media optimization, oxygen dependency, and genetic variation between luminescent and non-luminescent strains. Experiments revealed that 10% breadcrumb agar (BCA) significantly enhanced bioluminescence and colony size while supplementation with activated charcoal reduced luminescence. Comparative analysis of carbohydrate-based media showed that BCA outperformed malt extract and molasses in promoting luminescence. Oxygen was confirmed as essential for bioluminescence, with light emission ceasing rapidly under anaerobic conditions and recovering wi
