Biofilms were grown on preconditioned voice prostheses with biosurfactants obtained from probiotic bacteria Lactococcus lactis 53 and Streptococcus thermophilus A in an artificial throat model. Both biosurfactants greatly reduced microbial numbers on prostheses and also induced a decrease in the airflow resistance that occurs on voice prostheses after biofilm formation. This study presents a promising strategy for prolonging the lifespan of voice prostheses.
在人工喉模型中,使用从益生菌乳酸乳球菌53和嗜热链球菌A中获得的生物表面活性剂,在预处理过的语音假体上培养生物膜。两种生物表面活性剂都大大减少了假体上的微生物数量,并且还使生物膜形成后语音假体上出现的气流阻力降低。这项研究提出了一种延长语音假体使用寿命的有前景的策略。
