Table 1. Literature overview of the influence of substrates and supplements on the growth of G. lucidum and P. ostreatus.

Fungus	Substrate	Supplements	Results	Ref
G. lucidum	Oak sawdust	Rice bran, food waste compost	15% food waste compost gave highest yield of fruiting bodies. Higher concentration reduced the yield.	[10]
G. lucidum	Sawdust of hornbeam	Tea waste, wheat bran and CaCO3	20% of tea waste led to highest yield. Increased growth due to high amounts of K, N, Fe, Mg.	[11]
G. lucidum &	Wheat straw	Olive by-products	Increase in the protein content of P. ostreatus mycelium and in glucan for G. lucidum.	[12]
P. ostreatus
G. lucidum	Cotton stalk, maize straw, rice straw, sugarcane bagasse, wheat straw	Wheat bran and corn gluten	Rice straw showed the highest yield with increase in protein and polysaccharide content.	[13]
G. lucidum	Shredded cassava	Wheat bran, rice bran, MgSO4	Wheat bran more favourable than rice bran.	[14]
Ganoderma &	Spent mushroom substrate	Wheat bran and soybean flour	Food supplement increased the laccase activity and the formation of fruiting bodies.	[15]
P. ostreatus
G. lucidum	Alder, beech and oak sawdust, flax shives	N.A.	Higher yield on alder and beech sawdust.	[16]
G. lucidum	Sawdust from acacia	Soy residue from was tofu manufacturing.	Highest rate of mycelial growth for media ratios of C to N content on the growing substrate.	[17]
Ganoderma &	Leaves from hazelnut, tilia, European aspen, wheat straw, beech sawdust, waste paper	Wheat bran	Wheat straw led to higher growth. Wheat bran led to contamination.	[18]
P. ostreatus
P. ostreatus	Wood chips, boll, sugar beet pellet pulp, palm fiber	Wheat bran, rice bran, soya cake powder, rice bran, carrot pulp	Highest yield for boll, beet pellet and palm fiber with supplements.	[19]
P. ostreatus	Diaper and food waste.	N.A.	Showed it could grow.	[20]
P. ostreatus	Acacia sawdust, corncob, sugarcane bagasse	N.A.	Highest growth on corncob and sugarcane bagasse.	[21]
P. ostreatus	Poplar sawdust.	Food waste compost, rice bran	Optimum growth rate for 12% rice bran and 25% food waste	[22]
P. ostreatus	Rice straw, wheat straw, paper, sugarcane bagasse, sawdust of alder	Rice bran	Rice straw alone was found to give the highest yield	[23]
P. ostreatus	Potato dextrose agar, yam dextrose agar, sweet potato dextrose agar, malt extract agar	Molasses, glucose	Potato and yam dextrose agar led to the highest yield. Largest colony growth with 1 to 5% sucrose supplement.	[24]
P. ostreatus	Wheat stalk, millet stalk, soybean stalk, cotton stalk	N.A.	Highest yield on soybean stalk.	[25]
P. ostreatus	Sawdust from Triplochiton scleroxylon, rice straw, banana leaves, maize, corn husk, rice husk, elephant grass	N.A.	Highest yield on sawdust. The yield was found to correlate with the high cellulose, lignin and fibre content of the substrate.	[26]
P. ostreatus	Alfalfa, barley hay, sawdust (not specified), wheat hay	Salts	Highest growth on wheat hay and distilled water.	[27]
P. ostreatus	Sawdust (not specified)	Cassava peel, yam peel, plantain leaf	Sawdust supplemented with 10% cassava peel led to the best results.	[28]
P. ostreatus	Wheat straw	Grape pomace	Some toxicity from the grape pomace.	[29]
P. ostreatus	Sawdust from beech, oak and poplar, wheat and rye straw, by-products from the textile industry, flax and hemp shives	N.A.	Wheat and rye straw with flax shives led to the highest yield.	[30]
P. ostreatus	Empty fruit bunch and sugarcane bagasse	N.A.	Empty fruit bunch can be used.	[31]
P. ostreatus	Wheat straw, cotton gin-trash, peanut shells, poplar, oak sawdust, corn cobs, olive press-cakes	N.A.	Highest growth on the cotton gin-trash, peanut shells and poplar sawdust.	[32]
G. lucidum &	Wheat straw	Olive mill waste and olive pruning residues	Small concentration in olive mill and pruning residues increased the protein content in both fungi. Generally, P. ostreatus grew more than G. lucidum	[12]
P. ostreatus
G. lucidum &	Cellulose	Potato dextrose	Cellulose with potato dextrose led to higher growth presumably because simplest to digest.	[33]
P. ostreatus
P. ostreatus	Cocopeat with sawdust (not specified)	N.A.	50% cocopeat led to the highest yield.	[34]
