Plant-derived materials from L. (sage) have demonstrated significant antimicrobial potential when applied during fresh cheese production. In this study, the mechanism of action of sage components against , and was investigated through the development of predictive models that describe the influence of key parameters on antimicrobial efficacy. Molecular modeling techniques were employed to identify the major constituents responsible for the observed inhibitory activity. Epirosmanol, carvacrol, limonene, and thymol were identified as the primary compounds contributing to the antimicrobial effects during cheese production. The highest weighted predicted binding energy was observed for thymol against the KdpD histidine kinase from , with a value of -33.93 kcal/mol. To predict the binding affinity per unit mass of these sage-derived compounds against the target pathogens, machine learning models-including Artificial Neural Networks (ANN), Support Vector Machines (SVM), and Boosted Trees Regression (BTR)-were developed and evaluated. Among these, the ANN model demonstrated the highest predictive accuracy and robustness, showing minimal bias and a strong coefficient of determination (R = 0.934). These findings underscore the value of integrating molecular modeling and machine learning approaches for the identification of bioactive compounds in functional food systems.
来自鼠尾草的植物源材料在新鲜奶酪生产过程中应用时已显示出显著的抗菌潜力。在本研究中,通过建立描述关键参数对抗菌效果影响的预测模型,研究了鼠尾草成分对[具体菌种1]、[具体菌种2]和[具体菌种3]的作用机制。采用分子建模技术来确定对观察到的抑制活性起主要作用的成分。已确定表迷迭香醇、香芹酚、柠檬烯和百里酚是奶酪生产过程中产生抗菌作用的主要化合物。观察到百里酚对[具体菌种4]的KdpD组氨酸激酶的加权预测结合能最高,值为-33.93千卡/摩尔。为了预测这些鼠尾草衍生化合物对目标病原体的单位质量结合亲和力,开发并评估了包括人工神经网络(ANN)、支持向量机(SVM)和增强树回归(BTR)在内的机器学习模型。其中,ANN模型显示出最高的预测准确性和稳健性,偏差最小且决定系数很强(R = 0.934)。这些发现强调了整合分子建模和机器学习方法在功能性食品系统中鉴定生物活性化合物的价值。
