Abstract In this study, the optimum conditions for multi‐enzymatic recovery of cellulases produced by Aspergillus niger were investigated using sugarcane bagasse. Two extraction methods investigated: two‐stage solid–liquid (SLE) followed ultrasound‐assisted (UAE), and single‐stage SLE. The ultrasound effects evaluated a Doehlert design, in which pH (5.0–9.0) sonication power (0.8–2.0 W ml −1 ) independent variables. For SLE, temperature (25–45°C), time (10–60 min), analyzed Box–Behnken...
This research aimed to microencapsulate Saccharomyces boulardii using an experimental design 23 evaluate vegan and vegetarian wall materials, rice protein, maltodextrin in different proportions, drying temperature, feed flow. The microcapsules were characterized by encapsulation yield, moisture content, scanning electron microscopy, Fourier transform infrared spectroscopy, thermogravimetric analysis, survivability rate simulated gastric solution during storage under refrigeration. best yield...
Treatment of effluents from animal slaughterhouse industries is indispensable, standing out coagulation/flocculation/sedimentation processes. Bionanoparticles (BioNPs) (nanoparticles (NPs) functionalized with Moringa extracts (MO)) were studied as an alternative natural coagulant that would contribute to the microbial load reduction, without increasing treated effluent toxicity. MO prepared different salts, and then, in a kinetics study, NPs mass dosages evaluated. In best-defined...
Abstract The performance of the pomegranate peel extract against synthetic antioxidant additives on oxidation stability commercial biodiesel B100 derived from soybean was evaluated. experimental extraction conducted under 200 bar, 35, 45, and 55°C, 0.0, 2.5, 5.0 mL ethanol as co‐solvent. Due to rich in squalene α‐tocopherol composition, all extracts presented high capacity, 16.70 1.68 μg −1 . In tests, addition 1000 ppm supercritical resulted increment induction time pure by up 1.83....
A distributed parameter model and two lumped models were used in order to find the rate-limiting step adsorption process of a herbicide (Diuron) by Moringa oleifera husks, possible low-cost adsorbent. For that, four kinetics assays, differentiated initial Diuron concentration, performed. Langmuir isotherm well represented equilibrium data through this evaluation, husks proved be potential adsorbent for removal from water. The internal mass transfer resistance, analysed as model, was found...
Abstract Background The adequate management of dairy effluent is prime importance to mitigate environmental damages. In addition, its treatment could enable reuse inside the industry, contributing a sustainable economy. Results optimization coagulation/ flocculation/ sedimentation stage through Box–Behnken Design was proposed using real and natural coagulant Moringa extracted with CaCl 2 . Then, nanofiltration NF 270 membrane applied, raw wastewater pre‐treated sedimentation, enabling...
