Health Benefits of golden oyster mushroom
1. Treat obesity
Intake of golden oyster mushrooms inhibits weight gain, fat accumulation, and food intake. It enhances the activities of antioxidant enzymes and modulates the immune functions thus managing obesity .
2. Lower cholesterol level
Golden oyster mushroom decreases the triglycerides and low‐density lipoprotein (bad cholesterol) level.
It also increases high‐density lipoprotein (good cholesterol) levels and keeps the liver and kidney healthy thus, prevents diet‐induced hyperlipidemia.
3. Manage diabetes
Golden oyster mushroom contains a polysaccharide that controls blood glucose, insulin, and catalase levels in the blood.
It inhibits the enzyme responsible for the metabolism of saccharides and decreases the absorption of glucose into the blood.
4. Antitumor and cancer properties
Protein (polysaccharides or non lectin glycoprotein) from golden oyster mushrooms inhibits the proliferation of human tumor cells and induces apoptosis.
Thus, this mushroom enhances immunity and inhibits the growth of cancer like leukemia and liver cancer .
5. Boots immune response
Golden oyster mushroom contains beta-glucan, vitamin D2, and polysaccharides. These compounds activate macrophage cells that are involved in the detection and destruction of bacteria and other harmful organisms and improve immunity .
6. Treat inflammation
Beta-glucan found in golden oyster mushrooms inhibits the expression of cytokines that cause inflammation and promote the secretion of anti-inflammatory cytokine .
7. Anti-aging properties
High polyphenolic and flavonoid content in the golden oyster mushroom prevents the production of an enzyme that degrades collagen. Thus intake of this mushroom treats oxidative stress by antioxidant activity and reduces aging .
8. Antioxidant properties
The presence of phenols ergosterol and nicotinic acid in golden oyster mushrooms show higher antioxidant activities. These compounds remove harmful radicals and protect the body from various diseases .
9. Antimicrobial activity
Golden oyster mushroom contains glucosylceramide (membrane lipids) compound that inhibits the growth of Escherichia coli and Staphylococcus aureus. Thus, this mushroom fights against infection and prevents food decay .
10. Keep brain healthy
Golden oyster mushroom is rich in amino acids like γ-aminobutyric acid (GABA) and ornithine. This amino acid is required for brain functioning and mental activity. Moreover, it is also useful in the treatment of wasting muscles after illness or post-operative care.
Side effects of golden oyster mushroom

Golden oyster mushrooms are found in warm climates on fallen trees and stumps of trees such as oak, elm, and beech.
Due to its delicate features and short shelf life, this mushroom is generally not available in local grocery stores. Using different substrates or waste mixtures will in house also.
This mushroom is easy to grow and produces a high number of smaller fruits than other oyster mushrooms. This mushroom grows fast in a warmer environment.
It grows well in straw, sugar cane mulch, radish leaves, cauliflower leaves, pea pod shells, sawdust, coffee grounds, paper, or compost. Moreover, paddy straw mixed with other wastes i.e. brassica straw, pea pod shell, cauliflower leaves, and radish leaves gives good results. A research study suggested that this combination enhanced the protein, sugar, and amino acid content in the mushroom .
Add spawn into the substrate and incubate at 24 – 29°C for 10 – 14 days with humidity at 90-100%. Remember to shake once during colonization to speed up the growth.
- Primordia formation / Fruiting initiation – For fruiting maintain the temperature at 21 – 27°C with humidity of 98 – 100%. In 3 – 5 days fruiting happens. This mushroom grows well in light 500 – 1,000 lux with fresh air exchange of 4 – 8 per hour and CO2 below 1000 PPM.
- Fruiting and Harvest- The mushroom is ready to harvest within 3 – 5 days at temperature 21 – 29°C and humidity 90 – 95%. Harvesting should be done before the caps completely flatten out and immediately store in a refrigerator.
