“…Although there had been little studies done on this topic, there are evidences of mushroom strain improvement induced by irradiation. A study done by Jyothi and Thara [22] for instance, found that gamma-irradiated mushroom spawn enhances the biological efficiency of Pleurotus species and reduces the number of days required for primordial initiation. Moreover, a study using UV-irradiated mycelium instead of gamma irradiation also resulted in a 30% improvement in biological efficiency of the mutant strain [14].…”

Leading the palm oil industry, Malaysia strives to become the powerhouse of palm oil producers. However, it is crucial that the industry does not influence the environment negatively in any way. Thus, reusing and repurposing palm oil residues in mushroom farming is one of the potential solutions for agricultural waste management. In this study, the objective of this study is to determine the mycelial performance of V. volvacea in palm oil empty fruit bunch (EFB) fibre as substrate and to evaluate the mycelial growth performance of V. volvacea in two different substrate treatment. The substrate treatment involved the non-treated EFB fibres (N substrate) and EFB fibres treated with 10% Calcium Carbonate (CaCO3) (T substrate), and mycelium treatment involved in gamma-irradiated mycelium (G sample) and non-irradiated mycelium (NG sample). Results shows that mycelium inoculated on treated EFB fibres exhibited a higher growth rate compared to non-treated EFB fibres. The full colonization days of mycelial run-on substrate using treated substrate was found reduced from 15 days to 9 days, as compared to the non-treated substrate. However, gamma irradiated mycelium was found giving no significant changes to the rate of mycelial run. In conclusion, substrate treated with CaCO3, increased the growth of mycelium. In future, it is suggested to measure the effect of irradiation using different gamma irradiation exposure.

“…According to Djajanegara (2008), mutation might cause changes in the gene expression encoding biosynthetic enzymes resulting in an increase in the production and accumulation of bioactive components with antioxidative activity. Moreover, Jyothi and Thara (2021) reported the DNA variation of the mutants from single base pair change to repeated sequences. The polymorphism analysis using random amplified polymorphic DNA (RAPD) markers revealed that P. djamor, P. florida and P. ostreatus had 16.7%, 25% and 22% polymorphism with their respective improved strains.…”

Oxidative stress is a conjoint pathological mechanism that can be triggered by free radicals leading to cellular senescence or apoptosis. Antioxidants have the potential to inhibit free radicals’ generation and balance the irregulated oxidative stress to restore cellular homeostasis. Schizophyllum commune, also known as the split-gill mushroom, is well-known for its nutritional values and bioactive compounds. This study aimed to investigate the antioxidant activity and chemical composition of the hot water extracts of selected strains of S. commune including natural, gamma-irradiated and hybrid strains. The fruiting bodies of different strains of S. commune were subjected to hot water extraction and the extracts were evaluated by radical scavenging, and reducing capacity assays. Results showed that, overall, the antioxidant activity of the various strains was comparable. The natural strain W and the strain obtained when strain W was subjected to gamma-irradiation at a dose of 4000 Gy (W4000) consistently exhibited high antioxidant activities in all assays and they were either comparable or higher than common edible mushrooms, Pleurotus pulmonarius and Agaricus bisporus. Moreover, the gamma-irradiated strains R2000 and R4000 exhibited higher reducing activities (0.40 and 0.41 mmol Fe2+/g extract) than the parental strain R (0.27 mmol Fe2+/g extract).
