Kefir is a probiotic that has several health promising properties. Its grains can form microbial films on different types of substrates. In the present work, the surface characteristics of kefir biofilms associated with Maytenus rigida Mart. extract were minutely studied. Three different concentrations of plant extract were included in the biofilm forming solutions, where fresh grains of kefir were inoculated. The results showed that the plant extract was successfully incorporated into the exopolysaccharide matrix of the biofilm. The main chemical components found linked to the plant extract were triterpenes. The crystallinity of biofilms increased with the addition of the plant extract. The morphology revealed that at low concentrations of the extract there was a prevalence of lactobacilli, while at high concentrations yeasts were more observed. Adhesion and wettability were higher for biofilm with less extract. These results revealed that a combination of plant extract and kefir's exopolysaccharide could form biofilms with chemical and topographic properties of great interest in regenerative medicine.

生长在装有 Maytenusrigida 提取物的开菲尔上的聚合物微生物膜的结构评估
开菲尔是一种益生菌，具有多种有益健康的特性。它的颗粒可以在不同类型的基材上形成微生物膜。在目前的工作中，与Maytenusrigida Mart相关的开菲尔生物膜的表面特征。提取物进行了仔细研究。生物膜形成溶液中包含三种不同浓度的植物提取物，其中接种了新鲜的开菲尔谷物。结果表明，植物提取物成功地结合到生物膜的胞外多糖基质中。发现与植物提取物有关的主要化学成分是三萜。随着植物提取物的加入，生物膜的结晶度增加。形态学显示，在低浓度的提取物下，乳酸杆菌普遍存在，而在高浓度酵母中观察到更多。提取物较少的生物膜的粘附性和润湿性更高。这些结果表明，植物提取物和开菲尔胞外多糖的组合可以形成具有化学和地形特性的生物膜，这在再生医学中非常重要。
