Biofilm-forming Bacillus species are often involved in persistent contamination and spoilage of dairy products. Therefore, they present a major microbiological challenge in the field of dairy food quality and safety. Due to a vast physiological versatility, Bacillus species can survive in various sections of dairy manufacturing plants, leading to high risk in product spoilage and potential dissemination of foodborne diseases. Furthermore, biofilm and heat-resistant spore formation make these bacteria challenging to eliminate. Thus, some strategies have been employed to remove, prevent, or delay the formation of Bacillus biofilms in the dairy industry, but with limited success. Lack of understanding in the Bacillus biofilm structure and behavior in conditions relevant to dairy-associated environments could partially account for this situation. Current paper reviews dairy-associated biofilm formation by Bacillus species, with particular attention to the role of biofilm in Bacillus species adaptation and survival in a dairy processing environment. Besides, relevant model systems are discussed for developing novel antimicrobial approaches to improve the quality of dairy food. This article is protected by copyright. All rights reserved.

芽孢杆菌在乳制品行业生物膜持久性和新兴抗生物膜策略中的作用

形成生物膜的芽孢杆菌通常与乳制品的持续污染和腐败有关。因此，它们对乳制品质量和安全领域提出了重大的微生物挑战。由于具有广泛的生理多样性，芽孢杆菌可以在乳制品制造厂的各个部分存活，从而导致产品腐败和食源性疾病潜在传播的高风险。此外，生物膜和耐热孢子的形成使这些细菌难以消除。因此，已经采用了一些策略来去除、预防或延迟乳制品行业中芽孢杆菌生物膜的形成，但效果有限。在与乳制品相关环境相关的条件下，对芽孢杆菌生物膜结构和行为缺乏了解可能部分解释了这种情况。当前论文回顾了芽孢杆菌属物种与乳制品相关的生物膜形成，特别关注生物膜在乳制品加工环境中芽孢杆菌属物种的适应和生存中的作用。此外，还讨论了相关模型系统，以开发新的抗菌方法以提高乳制品的质量。本文受版权保护。版权所有。
