Abstract
Hericium erinaceus (lion’s mane) is a commonly cultivated fungi that has shown promise in recent studies investigating its medicinal effects. Studies have shown the ideal substrate for cultivation of H. erincaceus is a mixture of hardwood sawdust and wheat bran. Additionally, certain food waste products have been shown to supplement the substrate mixture effectively. No studies have investigated how the addition of spent coffee grounds (SPG) to the substrate mixture on H. erincaceus impacts cultivation. This study examined the effect of SPG addition at 0%, 10%, 20% and 30% of the substrate mixture by mass. However, all bags were contaminated and no H. erincaceus grew. This likely happened because thermogenic mycelial growth raised the substrate temperature past the optimal growth range, the rye berry inoculation mix was not allowed to grow long enough, and the substrate bags were not completely sterilized during autoclaving. These led to sub-optimal growth of H. erinaceus, allowing for it to be out-competed and unable to grow in the substrate bags. Following studies will work to reduce the thermogenic impact on substrate temperature, improve sterilization practices and increase the inoculation growth period.
