Cultivation of some medicinal mushrooms species from Ganoderma on sawdust supplemented with water hyacinth | Gojenje nekaterih vrst zdravilnih gob iz rodu Ganoderma na žagovini, dopolnjeni z vodno hijacinto

English. This study investigated the cultivation of Ganoderma mbrekobenum, G. sessile, and G. oregonense using sawdust supplemented with water hyacinth (Eichhornia crassipes). Ganoderma species have medicinal applications, including immune modulation, antioxidants, and antimicrobial properties. Substrates with water hyacinth (SWH) consisted of 900 g sawdust, 100 g water hyacinth, 100 g rice bran, and 30 g calcium carbonate, while (SNWH) was not supplemented with water hyacinth. Mycelial growth assessment showed that G. mbrekobenum and G. sessile colonized 85 mm Petri dishes within 7 days, whereas G. oregonense required 8 days. Primordial development was highest in G. mbrekobenum (8.2), followed by G. sessile (4.0) and G. oregonense (2.8), but G. sessile and G. oregonense fruited faster (21 days) than G. mbrekobenum (30 days). Fruiting body yield analysis showed that G. mbrekobenum had the highest weight (61.10 g) and biological efficiency (15.42 %). G. sessile had the fastest fruiting time (47.4 days), while G. mbrekobenum took 86.8 days. The biological efficiency of G. oregonense was lowest at 9.99 % (SWH) and 5.86 % (SNWH). Water hyacinth supplementation improved mushroom yield and G. mbrekobenum demonstrated superior yield, whereas G. sessile had a faster fruiting cycle, making both species suitable for large-scale medicinal mushroom production.

Slovenian. Ta študija je preučevala gojenje Ganoderme mbrekobenum, G. sesile in G. oregonense na žagovini, dopolnjeni z vodnim hijacintom (Eichhornia crassipes). Vrste Ganoderme imajo medicinske lastnosti, kot so imunska modulacija, antioksidativno in protimikrobno delovanje. Substrati (SWH) so vsebovali 900 g žagovine, 100 g vodnega hijacinta, 100 g riževih otrobov in 30 g kalcijevega karbonata s 65 % vlage, medtem ko (SNWH) ni imel hijacinta. G. mbrekobenum in G. sessile sta kolonizirali petrijevke v 7 dneh, G. oregonense v 8 dneh. Prvobitni razvoj je bil najvišji pri G. mbrekobenum (8,2), sledili sta mu G. sessile (4,0) in G. oregonense (2,8). G. sessile in G. oregonense sta rodili v 21 dneh, G. mbrekobenum v 30 dneh. G. mbrekobenum je imel največji pridelek (61,10 g) in biološko učinkovitost (15,42 %), vendar je za plodove potreboval najdlje (86,8 dni). G. sesile je imela najhitrejši čas plodov (47,4 dni). Biološka učinkovitost G. oregonense je bila najnižja (9,99 % in 5,86 %). Dodatek vodnega hijacinta je izboljšal pridelek, G. mbrekobenum pa se je izkazal kot najdonosnejši, medtem ko je bil G. sessile primernejši za hitrejšo proizvodnjo.
