20.500.12556/RUL-176671 Penicillium expansum adhesion to materials used in food industry Penicillium expansum causes rotting of fruits and vegetables and form secondary metabolites that present a food safety risk. The main purpose was to determine P. expansum adhesion to materials used in the food industry. Adhesion was evaluated with crystal violet method and observed with scanning electron microscopy (SEM). Adhesion was stronger when an inoculum was prepared from a 10-day-old colony than from a 7-day-old colony. Further, adhesion was evaluated on different materials and physical properties of investigated materials were determined. P. expansum adhered to all investigated materials inmira declining order polystyrene (PST), polypropylene (PP), high-density polyethylene (HDPE), polyethylene terephthalate (PET), glass (G), stainless steel (SS). SEM observation confirmed adhered conidia and mycelium of P. expansum on all investigated materials, except SS where only conidia were observed. SEM also revealed that conidia were surrounded with extracellular polymorphic substances especially in case of HDPE, G and PET. The physical properties of the materials (contact angle, roughness, zeta potential) showed a minor role in P. expansum adhesion to investigated materials. Since adhesion leads to biofilm formation, preventing the adhesion of P. expansum would reduce the likelihood of food contamination by molds, indicating the need for further studies. filamentous fungi Penicillium expansum adhesion food contact materials plesni Penicillium expansum adhezija plesni biofilm živila embalažni materiali true false true Angleški jezik Slovenski jezik Članek v reviji 2025-12-08 14:21:51 2025-12-08 14:21:56 2025-12-23 04:08:40 0000-00-00 00:00:00 2025 0 0 Str. 1803-1815 no. 16 Vol. 101 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 579.67:582.282.123.2 0021-8464 10.1080/00218464.2025.2499549 234966275 Penicillium_expansum_adhesion_to_materials_used_in_food_industry.pdf Penicillium_expansum_adhesion_to_materials_used_in_food_industry.pdf 1 A7A07BAA5BD3A82821CA858D2A3C534A 28f1c5b0a0271033ccf28969f09d2469358b04e7b91d855f860b4ec60c8ea9be a9443895-d438-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223156 https://www.tandfonline.com/doi/full/10.1080/00218464.2025.2499549 1 75d29036-d438-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=223155 Biotehniška fakulteta Zdravstvena fakulteta 0 0 0
