Enzymatic immobilization emerges as a viable solution, enabling enzyme reuse. This study investigated the immobilization of an enzymatic extract obtained from Moniliophthora perniciosa fermentation in calcium alginate spheres using the direct trapping method. Initial tests assessed β-glucosidase activity, showing that a higher concentration of calcium chloride (1 M) alongside larger diameter spheres yielded improved results. The immobilized enzyme was reused for up to 17 cycles without significant loss of activity. The percentage of reducing sugars after 48-h hydrolysis with the supplemented enzymatic extract was 226%, doubling the value achieved with only the free enzymatic extract. The immobilized enzyme retained 50% of its initial activity after 1 h at 80 °C, demonstrating higher activity at pH 6 and 60 °C. These findings suggest that this immobilization technique is simple, economically viable, and effective for the hydrolysis of pretreated sugarcane bagasse.HIGHLIGHTSSuccessful immobilization of M. perniciosa enzymatic extract achieved through direct entrapment in calcium alginate.Immobilized β-glucosidase demonstrates sustained activity over 16 reuse cycles, showcasing the potential for cost-effective bioconversion processes.Enhanced hydrolysis of sugarcane bagasse observed with immobilized enzymatic extract, indicating a promising approach for improved biomass utilization.Keywords: β-Glucosidase immobilizationmoniliophthora perniciosacalcium alginate spheressugarcane bagasse hydrolysisenzymatic bioconversionlignocellulosic ethanolreducing sugars AcknowledgmentsWe thank the Biotechnology Graduate Program of State University of Feira de Santana (UEFS/FIOCRUZ), the Coordenação de Aperfeiçoamento Pessoal de Nível Superior (CAPES) for a doctoral scholarship (88882.447813/2019-01), the Bahia State Research Support Foundation (FAPESB), and the National Council for Scientific and Technological Development (CNPq).Authors’ contributionsAll authors contributed to the study conception and design.

This study aims to use the design of experiment (DOE) approach to develop spray-dried encapsulated trypsin nano-powder (TrySP) with maximum activity and stability using a Büchi B-90 nano spray dryer. A 53 full factorial design with 26 randomly ordered experiments was created to study the impact of process variables on the quality attributes of TrySP. The additive concentration (%), mesh cap size (μm), inlet temperature (Tinlet) (°C), trypsin concentration (%), and additive type (Mannitol or trehalose) were selected as the independent variables. The dependent parameters were yield value, particle size, residual enzyme activity, and moisture content. Further, comparative physicochemical and kinetic characterization of TrySP was performed. TrySP had diverse qualities (yield value 60.2–96.8%, residual activity >90–50%, particle size 314–1030 nm, and moisture content 0.7–2.2%). Optimized TrySP exhibited 89% yield value and 95% residual activity in the presence of 8% (w/w) mannitol. Kcat of TypSP increased from 22.5/s to 25.6/s with improved operational and storage stabilities. The half-life (t1/2) of TrySP showed 6 folds increase. Furthermore, TrySP activation energy increased from 45,918 J/mol to 94,491 J/mol. The sustainable model presented in this study enables the development of a thermostable, encapsulated trypsin nano-powder with physical and chemical properties that are optimized for various biotechnological industrial applications.Keywords: Büchi B-90 spray dryingdesign of experimentsimmobilizationtrypsin enzyme formulationkinetic parametersnano powder Authors’ contributionsHM established, designed, and carried out some of the experiments, assisted with data analysis, and wrote the majority of the manuscript.

However, layered hydroxide salts (LHSs), another group of brucite-like nanomaterials, have not yet been used for enzyme immobilization. In this work, we prepared two types of layered hydroxide salts, zinc hydroxide nitrate (ZHN: Zn5(OH)8(NO3)2.2H2O) and zinc hydroxide chloride (ZHC: Zn5(OH)8Cl2.H2O) and used them to immobilize Pseudomonas cepacia lipase (LipPS). The best protein loading for both ZHN and ZHC was 162.5 mg g−1 of LHS, which gave high values of triolein-hydrolyzing activity in organic medium (103 U g−1 for LipPS-ZHN and 105 U g−1 for LipPS-ZHC), immobilization efficiencies above 90% and activity retentions above 170%. In the kinetic resolution of (R,S)-1-phenylethanol, LipPS-ZHN gave better results, with 50% conversion being obtained in 2 h and an ees of 99%. With LipPS-ZHC, the conversion at 2 h was 40% and the ees, was lower, only 73%. For both immobilized materials, the eep was higher than 99% and E was higher than 200. The immobilized materials were stable after 5 cycles of reuse in successive 2-h kinetic resolutions. These results demonstrate that the layered hydroxide salts ZHN and ZHC have good potential as supports for the immobilization of lipases.Keywords: Pseudomonas cepacia lipaseimmobilizationlayered hydroxide saltsenzymatic kinetic resolution Authors’ contributionsAll authors contributed to the conception and design of the study.
