Povzetek


Šitaka je užitna goba, avtohtona v vzhodni Aziji. V raziskavi je bila preučevana tekočina za namakanje substrata kot sredstvo za njegovo obogatitev. Količina hranil v substratu se močno zmanjša med rastjo in razvojem micelija od inokuluma do faze porjavenja. Nekaj od tega zmanjšanja bi lahko nadomestili z namakanjem substrata v vodi, obogateni s hranili. V raziskavi je bila tekočina za namakanje substrata obogatena z nekaterimi dopolnimi snovmi, učinki tega obogatenja so bili ovrednoteni na osnovi nekaterih pomembnih lastnosti gob. Največja biološka učinkovitost (69,88 %) je bila pridobljena, če so bili bloki substrata namočeni v suspenziji vode z otrobi pšenice. Največ suhe snovi so imele gobe, kadar je bil substrat namočen s suspenzijo riževih otrobov. Izsledki te raziskave kažejo, da bi lahko nekatere pomembne lastnosti šitak izboljšali z namakanjem blokov substrata v vodi obogateni s hranili. Glede na rezultate je bila suspezija pšeničnih otrobov najboljša za povečanje produktivnosti šitak, suspenzija riževih otrobov pa za izboljšanje kvalitete gob.
