Abstract

Gljive (makrofungi ili „više gljive“) se mogu koristiti u razne svrhe - kao hrana, za proizvodnju krmiva, u humanoj i veterinarskoj medicini te u kozmetici. Najveći dio makrofunga spada u odjeljke Ascomycota i Basidiomycota. S biotehnološkog stajališta makrofungi su prilično zanemarena skupina za razliku od nižih gljiva koje imaju puno širu primjenu. Zahvaljujući enzimima koje proizvode, gljive se mogu uzgajati na lignoceluloznim materijalima, koji su teško razgradivi. U lignocelulozne materijale pripadaju i otpatci iz poljoprivredne i drvne industrije, npr. kukuruzovina, kukuruzni oklasci, pšenična slama, drvni otpad i razne vrste trava. Navedene sirovine mogu se koristiti za uzgoj gljiva na čvrstim supstratima (eng. solid-state fermentation, SSF) pri čemu se proizvodi biomasa, različiti spojevi koji mogu imati biološku aktivnost i enzimi koji razgrađuju lignocelulozu i ksenobiotike. Takav način uzgoja je istovremeno ekološki opravdan je se iskorištava otpadni matrijal koji nije adekvatno zbrinut. Ovaj završni rad opisuje uzgoj odabranih vrsta gljiva u SSF-procesima i navodi mogućnosti primjene takvih postupaka na lignoceluloznim sirovinama dostupnim u Republici Hrvatskoj.

Abstract (english)

Mushrooms (macrofungi or higher fungi) can be used for a variety of purposes - in food and feed production, in human and veterinary medicine as well as in cosmetics. Most of mushrooms belong to Ascomycota and Basidiomycota sections. In contrast to microfungi, which have much broader application, mushrooms are pretty neglected group from the biotechnological standpoint. Due to enzymes they produce, mushrooms can be cultivated on lignocellulosic materials, which are hardly degradable. Examples of lignocellulosic wastes are agricultural waste and waste from wood industry, e.g. corn stalks, corn cobs, wheat straw, wood waste and grass). These materials can be utilised for mushroom cultivation by solid-state fermentation (SSF) to produce mushroom biomass, different compounds that have biological activity and enzymes that degrade lignocelulose or xenobiotics. This way of cultivation is both environmentally justifiable and exploits the waste material that is not adequately disposed. This final work describes cultivation of selected species of fungi in SSF-processes and the possibility of their cultivation on lignocellulosic raw materials available in the Republic of Croatia.
