The problem of microbial biofilms has come to the fore alongside food, pharmaceutical, and healthcare industrialization. The development of new antibiofilm products has become urgent, but it includes bioprospecting and is time and money-consuming. Contemporary efforts are directed at the pursuit of effective compounds of natural origin, also known as "green" agents. Mushrooms appear to be a possible new source of antibiofilm compounds, as has been demonstrated recently. The existing modeling methods are directed toward predicting bacterial biofilm formation, not in the presence of antibiofilm materials. Moreover, the modeling is almost exclusively targeted at biofilms in healthcare, while modeling related to the food industry remains under-researched. The present study applied an Artificial Neural Network (ANN) model to analyze the anti-adhesion and anti-biofilm-forming effects of 40 extracts from 20 mushroom species against two very important food-borne bacterial species for food and food-related industries- and . The models developed in this study exhibited high prediction quality, as indicated by high r values during the training cycle. The best fit between the modeled and measured values was observed for the inhibition of adhesion. This study provides a valuable contribution to the field, supporting industrial settings during the initial stage of biofilm formation, when these communities are the most vulnerable, and promoting innovative and improved safety management.
随着食品、制药和医疗保健行业的工业化,微生物生物膜问题日益凸显。新型抗生物膜产品的研发变得紧迫,但这包括生物勘探,既耗时又费钱。当代的努力方向是寻找天然来源的有效化合物,即所谓的“绿色”制剂。最近的研究表明,蘑菇似乎是抗生物膜化合物的一个可能新来源。现有的建模方法旨在预测细菌生物膜的形成,而非在抗生物膜材料存在的情况下。此外,建模几乎完全针对医疗保健领域的生物膜,而与食品工业相关的建模研究仍不足。本研究应用人工神经网络(ANN)模型,分析了20种蘑菇的40种提取物对食品及食品相关行业中两种非常重要的食源细菌的抗黏附及抗生物膜形成作用。本研究中开发的模型显示出较高的预测质量,训练周期内的高r值表明了这一点。在抑制黏附方面,模型值与测量值之间的拟合度最佳。本研究为该领域做出了宝贵贡献,在生物膜形成的初始阶段为工业环境提供支持,此时这些群落最为脆弱,并促进创新和改进安全管理。
