Microorganisms in Agriculture and Food industry

1.4K
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...

  • 为了比较两种大米品种的污染水平.
  • 评估加工对真菌和真菌毒素负载的影响.

主要方法:

  • 分离和鉴定真菌属 (Penicillium,Alternaria,Aspergillus,Fusarium,Talaromyces) 的情况.
  • 针对22种毒素进行多种真菌毒素查.
  • 集群分析以基于真菌和毒素配置的样进行分组分析.

主要成果:

  • 变种II显示了更高的Alternaria流行率 (63%) 和显著的亚酸 (TeA) 污染 (>4000μg/kg).
  • 处理减少了真菌负载,但TeA,泽拉伦 (ZEN),15-乙-脱氧尼瓦伦 (15-AcDON) 和素 (CIT) 仍然存在.
  • 与TeA和ZEN共同聚集的Alternaria,表明了现场污染.

结论:

  • 抛光大米并不能消除菌毒素的风险.
  • 整个大米供应链的综合管理至关重要.
  • 由真菌污染物造成的消费者健康危害需要全面监测.
