| Popis: | Tri soja gljive bukovače, P. ostreatus NS 77, P. ostreatus NS 355 i P. ostreatus 244,gajena su na supstratima četiri biljne vrste, pšenica, kukuruz, soja i suncokret, kaosamostalni supstrati i u kombinaciji sa pšeničnom slamom. Nakon plodonošenjavršena su ispitivanja odgajivačkih, morfoloških, hemijskih, svojstva gljiva, kao ihemijske i mikrobiološke sirovim supstratima u odnosu na sadržaj celuloze usupstratima nakon plodonošenja sojeva, dok je kod sadržaja pepela obrnuto, u sirovimsupstratima je niži u odnosu na supstrate nakon plodonošenja. Koncentracija ukupnogbroja mikroorganizama, brojnost amonifikatora i brojnost saprofitnih gljiva nanesterilisanim supstratima je niža nego na iskorištenim supstratima. Dehidrogenaznaaktivnost je najviša na supstratima nakon plodonošenja soja NS 244, dok kodenzimskog kompleksa celulaza varira u zavisnosti od soja i supstrata Kod sva tri sojamaksimalni prinosi su bili na supstratu Soja (S5), a minimlni na supstratu Pšenica(S1). Na osnovu morfoloških osobine konstatovana je velika varijabilnist izmeđusojeva. Supstrat Kukuruz (S6) se pokazao kao najbolji, sa aspekta vodnog režima, dokse Suncokret (S7) pokazao kao najlošiji. Na supstratu Kukuruz (S6) je najviši, a nasupstratu Pšenica (S1) je najniži sadržaj pepela. Sadržaj natrijuma u nožici je veći odsadržaja u šeširu, što je obrnuto u odnosu na druge mikroelemente i makroelemente.Sadržaj celuloze je viši u svim sirovim supstratima, dok je kod sadržaja pepelaobrnuto. Brojnost svih mikroorgnaizma na nesterilisanim supstratima je niža nego naiskorištenim supstratima. Dehidrogenazna je najviša na supstratima nakonplodonošenja soja NS 244, dok kod enzimskog kompleksa celulaza varira u zavisnostiod soja i supstrata. Three strains of oyster mushroom (P. ostreatus NS 77, NS 355, and 244) were grown on substrates made from four crops (wheat, maize, soybean, and sunflower), as individual substrates or in combination with wheat straw. After fruit maturity, mushroom growing, morphological, and chemical properties were analysed, as well as chemical and microbiological analyses of fresh and used substrates. All three strains showed maximum yields on soybean substrate (S5), and minimum yields on wheat substrate (S1). A large variability among the strains was observed based on the morphological properties. The strain NS 77 has caps of the smallest weight, width and length, the largest number of fruiting bodies, and the longest stalks. The strain NS 244 have caps of the largest weight, width and length, the lowest number of fruiting bodies and stalk length, but the largest width of the stalks. Regarding water regime, maize substrate (S6) was the best, while sunflower (S7) was the poorest. Ash content was the highest in maize substrate (S6) and the lowest in wheat substrate (S1). Potassium content in the stalk was higher than in the cap, which is opposite from other micro- and macro elements. Cellulose content was higher in all fresh substrates than in the used substrates after the strains have fruited, while ash content was higher in the used substrates. Concentration of total number of microorganisms, abundance of ammonifiers and saprophytic fungi in the unsterilized substrates were lower than in the used ones. Dehydrogenase activity was the highest in substrates after fruiting of NS 244, while cellulose enzyme complex varied regarding the strain and substrate. |
