Filamentous fungi can be used for the valorization of food waste as a value-added product. The goal this study was bread through fungal cultivation and production products. verified upscaling from shake flasks to bench-scale bioreactor (4.5 L) pilot-scale (26 L). fungus showed ability grow without any additional enzymes or nutrients, it able consume concentration 4.5% (w/v) over 48 h. biomass in 4.1 g/L at 2.5% concentration, which increased 22.5 15% concentration. concentrations obtained...
Here, cell wall of a zygomycete fungus, Rhizopus delemar, grown on bread waste was wet spun into monofilaments. Using the whole material omits common chitosan isolation and purification steps leads to higher utilization. The fungal contained 36.9% 19.7% chitin, respectively. Solid state NMR confirmed presence chitosan, other carbohydrates. Hydrogels were prepared by ultrafine grinding wall, followed addition lactic acid protonate amino groups subsequently monofilament inhibited growth...
The cell wall of a zygomycetes fungus was successfully wet spun into monofilament yarns and demonstrated as novel resource for production sustainable textiles. Furthermore, the could be cultivated on bread waste, an abundant food waste with large negative environmental impact if not further utilized. Rhizopus delemar first in bubble column bioreactor. fungal collected through alkali treatment biomass contained 36 23% glucosamine N-acetyl representing chitosan chitin wall, respectively. amino...
Abstract High-density polyethylene (HDPE) was compounded with 3 wt% carbon nanotubes (CNTs). In order to simulate mechanical recycling, both the nanocomposite and neat HDPE were repeatedly extruded subsequently analysed by tensile tests, Charpy impact strength, differential scanning calorimetry (DSC), oxidation induction time (OIT), Gel Performance Chromatography (GPC), Fourier Transform Infrared Spectroscopy (FTIR) TEM After 10 cycles of extrusion, thermal, mechanical, rheological tests did...
The fungus Rhizopus delemar was grown on bread waste in a submerged cultivation process and wet-laid into films. Alkali or enzyme treatments were used to isolate the fungal cell wall. A heat treatment also applied deactivate biological activity of fungus. Homogenization biomass done by an iterative ultrafine grinding process. Finally, cast films Ultrafine resulted densification Fungal showed tensile strengths up 18.1 MPa, Young's modulus 2.3 GPa strain at break 1.4%. Highest strength...
The current study aimed at the valorization of bread waste in a fungal biorefinery for recovery protein hydrolysate food applications and monofilaments medical textile applications. Rhizopus delemar was cultivated on 1 m3 airlift bioreactor to obtain biomass. isolated as soluble fraction after mild enzymatic treatment biomass with protease enzyme. recovered rich eight essential amino acids showed foaming emulsion properties. microfibers chitin chitosan were an insoluble during process. A...
Abstract The purpose of this study was to investigate the influence aging on properties high‐density polyethylene (HDPE) reinforced with multi‐wall carbon nanotubes (MWCNTs). Nanocomposites were prepared at 0, 1, 3, and 5 wt%. long‐term durability materials evaluated by thermo‐oxidative test. Test bodies aged 110°C for up 10 weeks. nanocomposites characterized differential scanning calometry, thermogravimetric analysis (TGA), 13 C‐NMR, elongation break, transmission electron microscopy....
Fungal mycelium is emerging as a source for sustainable bio-based materials. biomass of Aspergillus oryzae was prepared by cultivation on bread waste hydrolysate to valorize this abundant food waste. Chitin-glucan-rich alkali-insoluble material (AIM) isolated from fungal biomass, formed into hydrogels, and wet spun monofilaments. AIM in the form microfibers containing 0.09 g polymer glucosamine (GlcN)/g subjected freeze-thaw deacetylation treatments increase amount GlcN. The GlcN fraction...
