“…Zein has demonstrated to be an excellent material for electrospinning and has been successfully used to encapsulate diverse bioactive compounds Gómez-Mascaraque, Pérez-Masiá, González-Barrio, Periago, & Lopez-Rubio, 2017;Gomez-Mascaraque, Tordera, Fabra, Martínez-Sanz, & López-Rubio, 2019;Quek et al, 2019) and to generate biodegradable food packaging layers (Fabra, López-Rubio, & Lagaron, 2016). Zein is a plant protein that has found use in adhesive and coating materials for pharmaceutical, biomedical, and food applications, because of its nontoxicity, biodegradability, biocompatibility and economic reasons (Moradkhannejhad, Abdouss, Nikfarjam, Mazinani, & Heydari, 2018;Schmidt, Hamaker, & Wilker, 2018).…”

The interesting health-promoting properties of chilto, make these fruits excellent sources of natural functional food ingredients. For this reason, pulp, skin and seed extracts of chilto, previously characterized by Orqueda et al. (2017), were considered for inclusion in bioactive food packaging structures.Electrospinning has recently gained significant interest in the fields of bioactive encapsulation and functional food development as it is a relatively simple, versatile, low

“…The antibacterial activity of neat PHBH nanofibers, PHBH composite nanofibers with centella, propolis, and hinokitol against the gram-positive bacteria S. aureus and gram-negative bacteria E. coli was evaluated using inhibition zone method [20,33,40,41]. The antimicrobial effect of samples was evaluated at 37 • C (S. aureus) and 30 • C (E. coli) for 24 h. Table 4 presents the diameters of the inhibition zone for PHBH composite nanofibers with natural products.…”

Natural Antibacterial Reagents (Centella, Propolis, and Hinokitiol) Loaded into Poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] Composite Nanofibers for Biomedical Applications

Centella asiatica, propolis, and hinokitiol, as natural antibacterial reagents, were integrated into the poly[(R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate] (PHBH) polymer to produce antibacterial wound dressings, using electrospinning process. The results showed that the fiber diameters and surface morphology of PHBH composite nanofibers were influenced by the addition of ethanol–centella (EC), methanol–centella (MC), ethanol–propolis (EP), and ethanol–hinokitiol (EH) at various ratios compared to pristine PHBH nanofibers. From FT-IR, the nanofibrous samples with higher contents of natural antibacterial substances showed the peaks of carboxylic acid, aromatic ring, and tropolone carbon ring from centella, propolis, and hinokitiol, respectively. Furthermore, the tensile strength of neat PHBH nanofibers was increased from 8.00 ± 0.71 MPa up to 16.35 ± 1.78 MPa by loading of propolis (EP) 7% into PHBH. X-ray analysis explained that the loading of propolis (EP) was also able to increase the crystallinity in PHBH composite nanofibers from 47.0% to 54.5%. The antibacterial results demonstrated that PHBH composite nanofibers containing natural antibacterial products were potent inhibitors against the growth of Escherichia coli and Staphylococcus aureus, amongst them hinokitiol and propolis proved to be the most effective. Additionally, the release studies displayed that centella and hinokitiol had faster release from PHBH composite nanofibers in comparison to propolis.

“…Another biological material well-known for its good mechanical properties is the mycelium of different fungi. Usually, reports about fungicide properties of diverse nanofiber mats can be found in the scientific literature dealing with nanofiber mats and mentioning fungi [21,22,23,24,25]. Only very few studies investigate interactions between fungi and nanofiber mats in which the fungi grow on polymeric material.…”

Comparative Study of Pleurotus ostreatus Mushroom Grown on Modified PAN Nanofiber Mats

et al. 2019

View full text Add to dashboard Cite

Pleurotus ostreatus is a well-known edible mushroom species which shows fast growth. The fungus can be used for medical, nutritional, filter, or packaging purposes. In this study, cultivation experiments were carried out with Pleurotus ostreatus growing on polyacrylonitrile (PAN) nanofiber mats in the presence of saccharose and Lutrol F68. The aim of this study was to find out whether modified PAN nanofiber mats are well suited for the growth of fungal mycelium, to increase growth rates and to affect mycelium fiber morphologies. Our results show that Pleurotus ostreatus mycelium grows on nanofiber mats in different morphologies, depending on the specific substrate, and can be used to produce a composite from fungal mycelium and nanofiber mats for biomedical and biotechnological applications.
