概括

在食品加工环境中Listeria monocytogenes的持久性与特定的微生物伙伴有关,而不是总体的微生物多样性. 识别这些关联的属有助于制定针对性控制策略,以预防病原体的生存.

科学领域:

食品安全和微生物学
环境微生物学环境微生物学
微生物生态学微生物生态学

背景情况:

在食品加工环境 (FPE) 中Listeria monocytogenes的持久性挑战了对微生物社区动态的理解.
目前的病原体控制策略通常基于对微生物多样性和病原体存在的假设.

研究的目的:

系统地审查和对调查Listeria spp.的研究进行元分析. 在FPE中的微生物和微生物群落.
为了确定在FPE中Listeria存在和微生物α多样性之间的关系.
确定与FPE中的Listeria持久性相关的特定微生物属.

主要方法:

按照PRISMA指南进行系统审查和元分析.
搜索了PubMed,科学网和食品科学与技术摘要数据库.
分析了7项研究,包括1659个来自肉类和生产FPE的环境样本,使用元基因组学和差异丰度分析.

主要成果:

在Listeria存在和微生物社区的总体α多样性 (Shannon,反向Simpson,Chao1指数) 之间没有发现显著的相关性.
伪omonas,Psychrobacter和Acinetobacter属最常与李斯特菌的存在有关.
在一项研究中,Veillonella被确定与L. monocytogenes有显著的关联,这表明潜在的无氧相互作用.

结论:

在FPE中Listeria monocytogenes的持久性与特定的微生物伙伴有关,而不是一般的多样性指标.
相关属,特别是生物膜形成者,可能为李斯特菌的生存提供结构和代谢支持.
调查结果表明,针对这些特定微生物伙伴的有针对性的控制策略是有效控制FPE中的Listeria的必要条件.

Microorganisms in Agriculture and Food industry

Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Biological Methods for Microbial Control

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...
