“…Treatment with alkali impregnation followed by steam pretreatment at 200 C with a residence time of 90 s was found to be optimal for this purpose. In another study, steam pretreatment of hemp fibres at 185 C for 2 min increased the cellulose content from 60% to 74%, whereas enzyme (pectinase) assisted retting followed by steam pretreatment resulted in a 78% cellulose content of the remaining solid material [18]. Enhancing the enzymatic breakdown of hemp via electron beam irradiation was previously tested [19], where the improvement in enzymatic hydrolysis was more evident in the hydrolysis of xylan than in that of cellulose.…”

“…[25] oraz Nykter i wsp. [26] oceniali zanieczyszczenie drobnoustrojami włókien konopi i siemienia lnianego. W zależności od pory roku, w której zbierany był badany materiał, stężenia bakterii i grzybów wahały się w zakresach (odpowiednio): na włóknach konopi -4,5×10 4 -1,7×10 6 jtk/g i 3,4×10 2 -3,7×10 4 jtk/g, na włóknach siemienia lnianego -1×10 2 -7,9×10 9 jtk/g i 3×10 3 -2,4×10 7 jtk/g.…”

Identyfikacja jakościowa mikrobioty tych włókien wykazała obecność grzybów pleśniowych (głównie z rodzajów Alternaria, Arthrinium, Aspergillus, Bipolaris, Chaetomium, Cladosporium, Penicillium, Pullularia, Rhizopus, Sordaria i Stachybotrys) i drożdżoidalnych oraz bakterii (w tym promieniowców z rodzaju Streptomyces) [26,27].…”
