“… 54 The treatment has in fact proven effective for fibers of the herbaceous plant Syngonanthus nitens , with a low content of lignin (6.5%), 44 but not for sugar palm fibers with a lignin content of 13.4%. 55 Lignin content of loquat leaves is estimated to be 19.2% of the overall lignocellulosic fraction. 47 A consequent bleaching step was considered necessary to enhance cellulose weight fraction in the pre-treated biomass, in order to make it more available for enzyme aggression.…”

Co-immobilization of Cellulase and β-Glucosidase into Mesoporous Silica Nanoparticles for the Hydrolysis of Cellulose Extracted from Eriobotrya japonica Leaves

Fungal cellulases generally contain a reduced amount of β-glucosidase (BG), which does not allow for efficient cellulose hydrolysis. To address this issue, we implemented an easy co-immobilization procedure of β-glucosidase and cellulase by adsorption on wrinkled mesoporous silica nanoparticles with radial and hierarchical open pore structures, exhibiting smaller (WSN) and larger (WSN-p) inter-wrinkle distances. The immobilization was carried out separately on different vectors (WSN for BG and WSN-p for cellulase), simultaneously on the same vector (WSN-p), and sequentially on the same vector (WSN-p) in order to optimize the synergy between cellulase and BG. The obtained results pointed out that the best biocatalyst is that prepared through simultaneous immobilization of BG and cellulase on the same vector (WSN-p). In this case, the adsorption resulted in 20% yield of immobilization, corresponding to an enzyme loading of 100 mg/g of support. 82% yield of reaction and 72 μmol/min·g activity were obtained, evaluated for the hydrolysis of cellulose extracted from Eriobotrya japonica leaves. All reactions were carried out at a standard temperature of 50 °C. The biocatalyst retained 83% of the initial yield of reaction after 9 cycles of reuse. Moreover, it had better stability than the free enzyme mixture in a wide range of temperatures, preserving 72% of the initial yield of reaction up to 90 °C.

“…A peroxide-soda treatment and puri cation with sodium chlorite were applied according to the protocol described by Fitriana with modi cations [19]. The solid residue obtained after the treatment with FA/AA/Wa mixtures was introduced into a 100-mL ground-glass neck ask, and a hydrogen peroxide-NaOH-water solution, prepared by mixing (H 2 O 2 , 2%):(NaOH, 1%) in a ratio 5:1 (v: v), was added.…”

Cellulose is a natural polymer obtained from plants with applications in various industrial sectors such as pulp and paper, textiles, coatings, ber composites, and nanomaterials. This work studied the extraction of cellulose from a tropical agricultural plant residue (Ceiba pentandra) using formic acid (FA)-acetic acid (AA)-water (Wa) mixtures as a function of temperature, time, and composition the cooking solvent

Kulit pisang kepok merupakan hasil samping pengolahan pisang kepok yang merupakan jenis pisang yang sering digunakan sebagai bahan baku olahan pisang, dan bernilai ekonomis rendah. Kulit pisang kepok dapat dimaanfaatkan sebagai media pertumbuhan Acetobacter xylinum untuk menghasilkan selu-losa bakterial. Penelitian ini bertujuan mengetahui pengaruh penambahan gula dan lama fermentasi terhadap karakteristik selulosa bakterial yang dihasilkan, serta untuk penghasilan kombinasi penamba-han gula dan lama fermentasi terbaik untuk penghasilan selulosa bakterial dari kulit pisang kepok. Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) dua faktor. Faktor pertama penambahan gula yang teridiri dari 30, 35 dan 40 g. Faktor kedua yaitu lama fermentasi terdiri dari 7, 14 dan 21 hari. Data dianalisis dengan analisis varian dan dilanjutkan dengan Uji BNJ. Variabel yang diamati antara lain, kadar air, ketebalan, gula reduksi, kadar selulosa, hemiselulosa dan lignin. Hasil penelitian menunjukkan bahwa penambahan gula dan lama fermentasi berpengaruh terhadap rendemen, ketebalan, berat, selulosa, hemiselulosa, lignin, dan gula reduksi. Interaksi antar perlakuan berpengaruh terhadap berat, rendemen, ketebalan, kandungan hemiselulosa dan gula reduksi, namun tidak ber-pengaruh terhadap kandungan selulosa dan lignin. Perlakuan terbaik proses fermentasi untuk menghasilkan selulosa bakterial dengan karakteristik terbaik yaitu dengan penambahan gula 40 g dan lama fermentasi 14 hari. Karakteristik selulosa bakteri yang dihasilkan yaitu ketebalan, gula reduksi, ka-dar selulosa, berat, rendemen, kadar hemiselulosa dan lignin berturut-turut sebesar 0.104±0.01 cm, 1,65±0,09 mg/mL, 86,00±0,99%, 8,34±0,01 g, 3.33±0,01%, 5,80±0,1%, 2,30±0,28%.
