Bacterial biofilms pose significant challenges, from healthcare-associated infections to biofouling in industrial systems, resulting in significant health impacts and financial losses globally. Classic antimicrobial methods often fail to eradicate sessile microbial communities within biofilms, requiring innovative approaches. This review explores the structure, formation, and role of biofilms, highlighting the critical importance of exopolysaccharides in biofilm stability and resistance mechanisms. We emphasize the potential of microbial enzymatic approaches, particularly focusing on glycosidases, proteases, and deoxyribonucleases, which can disrupt biofilm matrices effectively. We also delve into the importance of enzymes such as cellobiose dehydrogenase, which disrupts biofilms by degrading polysaccharides. This enzyme is mainly sourced from Aspergillus niger and Sclerotium rolfsii, with optimized production strategies enhancing its efficacy. Additionally, we explore levan hydrolase, alginate lyase, α-amylase, protease, and lysostaphin as potent antibiofilm agents, discussing their microbial origins and production optimization strategies. These enzymes offer promising avenues for combating biofilm-related challenges in healthcare, environmental, and industrial settings. Ultimately, enzymatic strategies present environmentally friendly solutions with high potential for biofilm management and infection control.
细菌生物膜带来了重大挑战,从医疗保健相关感染到工业系统中的生物污垢,在全球范围内造成了重大的健康影响和经济损失。传统的抗菌方法往往无法根除生物膜内的固着微生物群落,因此需要创新方法。本综述探讨了生物膜的结构、形成和作用,强调了胞外多糖在生物膜稳定性和抗性机制中的关键重要性。我们强调了微生物酶法的潜力,特别关注糖苷酶、蛋白酶和脱氧核糖核酸酶,它们可以有效破坏生物膜基质。我们还深入探讨了诸如纤维二糖脱氢酶等酶的重要性,该酶通过降解多糖来破坏生物膜。这种酶主要来源于黑曲霉和齐整小核菌,优化的生产策略可提高其功效。此外,我们还探讨了果聚糖水解酶、海藻酸裂解酶、α淀粉酶、蛋白酶和溶葡萄球菌酶作为有效的抗生物膜剂,讨论了它们的微生物来源和生产优化策略。这些酶为应对医疗保健、环境和工业环境中与生物膜相关的挑战提供了有希望的途径。最终,酶策略提供了环境友好的解决方案,在生物膜管理和感染控制方面具有很高的潜力。
