TL;DR: In this article, the feasibility of using textile waste as feedstock for cellulase production through solid state fermentation was investigated, and the results indicated that using autoclaved textile blending cotton/polyester of 80/20 led to the highest cellulase activity.
Abstract: This study investigated the feasibility of using textile waste as feedstock for cellulase production through solid state fermentation. Aspergillus niger CKB was selected with the highest cellulase activity (0.43 ± 0.01 FPU g −1 ) after 7 days of cultivation on pure cotton. Material modification techniques including autoclaving, alkali pretreatment and milling were applied on six types of textiles with various cotton/polyester blending ratios. The results indicated that using autoclaved textile blending cotton/polyester of 80/20 led to the highest cellulase activity (1.18 ± 0.05 FPU g −1 ) with CMCase, β-glucosidase and avicelase activities of 12.19 ± 0.56 U g −1 , 1731 ± 4.98 U g −1 and 2.58 ± 0.07 U g −1 , respectively. The fungal cellulase was then extracted and applied to textile waste hydrolysis, in which a sugar recovery yield of 70.2% was obtained. The present study demonstrates a novel circular textile waste-based biorefinery strategy with recovery of glucose and polyester as value-added products.

TL;DR: All strains produced cellulase along with xylanase in solid state fermentation, while 70% of the strainsproduced cellulase-free x Dylanase during submerged fermentation.
Abstract: Seventy fungal strains were isolated from soils collected from different parts of southern Kerala, India. The strains were screened for xylanase production using Czapek’s agar medium. On the basis of clearing zones formed, 34 fungal strains were selected and identified. Solid state and submerged fermentation were done to identify strains that could produce maximum amount of xylanase, as well as to identify those strains that could produce cellulase-free xylanase under these conditions. All strains produced cellulase along with xylanase in solid state fermentation, while 70% of the strains produced cellulase-free xylanase during submerged fermentation.
Key words: Xylanase, Czapek’s agar, solid state fermentation, submerged fermentation
