Surfactant-Enhanced Enzymatic Hydrolysis of Eucalyptus Kraft Pulp: The Interrelationship Between Lignin Reduction and Sugar Recovery

Catalysts, Год журнала: 2025, Номер 15(1), С. 47 - 47

Опубликована: Янв. 7, 2025

This study examines the effect of surfactant-enhanced enzymatic hydrolysis on eucalyptus Kraft pulps produced under high (CPHA) and mild (CPMA) alkali conditions to optimize saccharification sugar yield. Compositional analysis revealed an increase in glucan content, from 40% untreated 70.1% CPHA. Both were hydrolyzed using Cellic® CTec3 HS enzyme (Novozymes). A 22 factorial design maximum conversion (~100%) with loading 10 FPU/g carbohydrate 10% (w/v) solids. Tween 20 significantly boosted CPMA, increasing reducing sugars 42 g/L 65 efficiency 59.6% 92.2% within 6 h. By contrast, 80 PEG 400 showed limited effects CPMA. Surfactants mitigated lignin–enzyme interactions, especially as higher lignin content restricted efficiency. Phenolic hydrolysates that increased release inhibitory compounds, while kept phenolic levels lower. Overall, improved yields even moderate removal during kraft pretreatment, highlighting its potential reduce costs industrial biorefineries. underscores importance optimizing surfactant selection based biomass composition for effective cellulosic recovery.

Optimization of L-Asparaginase Production from Aspergillus caespitosus: Solid-State and Submerged Fermentation Using Low-Cost Substrates and Partial Purification

Applied Microbiology, Год журнала: 2025, Номер 5(1), С. 19 - 19

Опубликована: Фев. 10, 2025

This work aimed to optimize the production of L-asparaginase (L-ASNase) from Aspergillus caespitosus CCDCA 11593 using Pereskia aculeata (Ora-pro-nóbis) leaf fiber as a substrate for solid-state fermentation (SSF), along with powdered whey protein in submerged (SmF) processes. A centered face design was applied evaluate effect different parameters. Additionally, L-ASNase partially purified on an ion-exchange cryogel column. For SSF, experimental condition, inoculum concentration 105 spores/mL, 120 h at 25 °C, 14% substrate, and 1% asparagine, corresponded highest enzymatic activity (2.75 U/mL) L-ASNase. SmF, condition greater (1.49 obtained medium containing 16% 24% 3.3% 4.7% spore 7 × 106 107 temperature range 29.8 34.8 pH 5.7 6.3, 87 fermentation. The SmF subjected adsorption tests, resulting 4.4 U/mg enzyme. study suggested that Ora-pro-nóbis could be low-cost production. column enzyme purification holds promise sustainable applications clinical food industries.
