Eco-benign synthesis of nano-gold chitosan-bacterial cellulose in spent ground coffee kombucha consortium: Characterization, microbiome community, and biological performance
In this study, we fabricated nano‑gold chitosan-bacterial cellulose (CBC-Au) via a facile in-situ method using spent ground coffee (SGC) in a kombucha consortium. The eco-benign synthesis of monodispersed gold nanoparticles (Au NPs) in modified bacterial cellulose (BC) was successfully achieved in the presence of chitosan (CHI) and a symbiotic culture of bacteria and yeast (SCOBY). The dominant microbiome community in SGC kombucha were Lactobacillaceae and Saccharomycetes. Chitosan-bacterial cellulose (CBC) and CBC-Au affected the microfibril networks in the nano cellulose structures and decreased the porosity. The modif...

Assessment and Biodegradation of Polycyclic Aromatic Hydrocarbons in Soil and Water Around Petroleum Products Depot Suleja, Nigeria
In this study, the polycyclic aromatic hydrocarbons (PAHs) present in soil and water in communities around Petroleum Products Marketing Company (PPMC) Suleja, Nigeria, were evaluated and degraded using indigenous microorganisms. The samples sites were divided into 7 plots from where samples of water and soil were obtained: one within the PPMC depot, five from communities surrounding the depot, and the control 93,000 km from the depot. The microbial counts were determined using spread plate inoculation technique on minimal salt media. The microbial isolates were characterized and identified based on their cultural, biochemi...

Electrospun polylactic acid nanofiber film modified by silver oxide deposited on hemp fibers for antibacterial fruit packaging
Int J Biol Macromol. 2023 Aug 28:126569. doi: 10.1016/j.ijbiomac.2023.126569. Online ahead of print.ABSTRACTBacterial and fungal contamination have become major factors in fruit spoilage and damage, posing a potential risk to human health. In this work, polylactic acid (PLA) nanofibers combined with Ag2O-hemp fibers for a good antimicrobial effect were developed and applied to antimicrobial fruit fresh-keeping packages. The results of molecular simulation calculations showed that the strength of hydrogen bonds between Ag2O and hemp fibers reached 45.522 kJ·mol-1, which proved that Ag2O and with hemp fibers formed a stable...

A "Magic Mushroom" Multi-Product Sesquiterpene Synthase
Chembiochem. 2023 Aug 23:e202300511. doi: 10.1002/cbic.202300511. Online ahead of print.ABSTRACTPsilocybe "magic mushrooms" are chemically well understood for their psychotropic tryptamines. However, the diversity of their other specialized metabolites, in particular terpenoids, has largely remained an open question. Yet, knowledge on the natural product background is critical to understand if other compounds modulate the psychotropic pharmacological effects. CubA, the single clade II sesquiterpene synthase of P. cubensis, was heterologously produced in Escherichia coli and characterized in vitro, complemented by in vivo p...

Anti-infective potential of the endophytic fungus < em > Aspergillus < /em > sp. associated with < em > Aptenia cordifolia < /em > root supported by metabolomics analysis and docking studies
In this study, Aptenia cordifolia associated endophytic fungi were explored for the first time. Seven isolates were identified morphologically followed by screening of these fungi by plug diffusion assay which revealed their potential activity against Staphylococcus aureus (ATCC 9144), Bacillus cereus (ATCC 14579), Serratia marcescens (ATCC 14756), Fusarium oxysporum (ATCC 48112), and Aspergillus flavus (ATCC 22546). Additionally, the crude ethyl acetate extract of the most potent three isolates in plug diffusion assay showed that Aspergillus sp. ACEFR2 was the most potent as anti-infective in disc diffusion assay; Accordi...

Chemical Composition, Mosquito Larvicidal and Antimicrobial Activities, and Molecular Docking Study of Essential Oils of Cinnamomum melastomaceum , Neolitsea buisanensis and Uvaria microcarpa from Vietnam
Chem Biodivers. 2023 Aug 2:e202300652. doi: 10.1002/cbdv.202300652. Online ahead of print.ABSTRACTThe leaf oil compositions of two Lauraceae and one Annonaceae plants cultivated in Vietnam were analysed by GC-MS (gas chromatography-mass spectrometry) analysis. The leaf oil of the first Lauraceae plant Cinnamomum melastomaceum contained 34 identified compounds, in which benzyl benzoate (38.5%), linalool (19.9%), (E)-caryophyllene (10.5%), and α-terpineol (6.9%) were the major compounds. The leaves of the second Lauraceae plant Neolitsea buisanensis gave an oil with the main compounds (E)-β-ocimene (24.0%), benzyl benzoate...

Bio-based antimicrobial food packaging films based on hydroxypropyl starch/polyvinyl alcohol loaded with the biosynthesized zinc oxide nanoparticles
Int J Biol Macromol. 2023 Jul 28:126011. doi: 10.1016/j.ijbiomac.2023.126011. Online ahead of print.ABSTRACTBio-based active food packaging materials have received much attention in the last decades. It is known that the traditional materials used for food packaging applications lack some critical characteristics such as resistance to the harmful microbes that cause damage to the preserved foods. Therefore, the current study aimed to find alternative packaging films based on efficient polymers. This research work was designed to prepare film mats using hydroxypropyl starch (HPS), polyvinyl alcohol (PVA), palmitic acid (PA)...
