Phytopathogenic fungi induce severe diseases in plant hosts, potentially leading to significant crop quantity and quality reductions. In this study, we isolated and identified pathogenic fungi that threaten the successful cultivation of annual and perennial crops in northern Thailand. Samples with leaf spots, fruit rot, wilting, and dieback symptoms were collected from 19 different crops in Chiang Rai, Chiang Mai, and Sakon Nakhon provinces in Thailand.

This study focused on optimizing fungal chitin (CT) production from a newly identified Fusarium incarnatum (GenBank: OL314753) for subsequent synthesis of submicron chitosan (sm-CS) tailored for enhanced heavy metal removal. Initial attempts to optimize CT yield using mixed nitrogen sources (potassium nitrate, peptone, yeast extract) via Box-Behnken Design (BBD) were insufficient for predicting optimal conditions. Consequently, Artificial Neural Networks (ANN) successfully modeled the BBD experimental data, the optimal nitrogen concentrations to 4.

This research presents the synthesis and application of a hybrid nanomaterial, Lanthanum (La) doped in reduced graphene oxide (rGO), embedded with a chitosan-decorated gum rosin (CS-GR) matrix mediated via pine tree, which is designed to address these dual challenges. The La-rGO/CS-GR nanomembrane (NMb) shows enhanced mechanical properties, with a tensile strength of 46 MPa at 4 wt% La-rGO doping, and achieves high adsorption efficiency for pollutants. The 4 wt% La-rGO/CS-GR: NMb demonstrated 85 % dye rejection efficiency for Congo red dye under filtration conditions, while also facilitating bio-electrochemical energy harvesting.

and are genera in Bionectriaceae, and known in sexual perithecial ascomata and hyphomycetous asexual morphs. In their asexual morph, both genera share similar morphology in conidiophores and conidiogenous cell characteristics but differ in the development of conidiophores. The members of are distributed worldwide with the majority occurring in the tropics and the species are commonly reported as soil-borne fungi but also reported as endophytes, epiphytes, and saprotrophs.

Cancer remains a predominant global health concern, necessitating effective treatment options. Conventional cancer therapies, particularly chemotherapy, often face constraints such as low selectivity, insufficient solubility, and multidrug resistance (MDR), which diminish effectiveness and exacerbate negative effects. Metal oxide nanoparticles (MONPs), such as iron oxide, zinc oxide, and copper oxide, offer a promising solution by enhancing targeted drug delivery, reducing systemic toxicity, and mitigating chemotherapy-induced disabilities like neurotoxicity and cardiotoxicity.

In response to the World Health Organization's research agenda of antimicrobial resistance in human health, this study appraised the antibacterial and antibiofilm synergistic activity of meropenem and ZnO nanoparticles (ZnO-NPs) combination against carbapenem-resistant Klebsiella pneumoniae (CRKP). The minimum inhibitory concentration (MIC) of meropenem in combination was found to be ~1/12 of its MIC alone. The results of microtiter dilution assay showed that the combination was more efficient in reducing the biofilm biomass than meropenem alone or ZnO-NPs alone.
