ABSTRACT Postharvest loss of sweet pepper and other fresh produce is a major challenge throughout the world. The control of the loss of these valuable farm produce is primarily based on the use of synthetic fungicides. Nevertheless, there are concerns based on the impact of these chemicals on the environment and human health. Hence, call for a much safer and environmentally friendly alternative. Among the various biological alternatives, the use of bacterial antagonistic strain is becoming popular throughout the globe. Bacterial antagonists are now controlling a number of postharvest pathogens. Several modes of action have been suggested by which microbial antagonists inhibit the growth of postharvest pathogens. However, very little is known about the overall diversity of microbial communities on harvested produce; and how these communities can serve as a foundation for research on postharvest biocontrol. Competition for nutrients and space is the most widely accepted mechanism of action for bacterial antagonists. In addition, antibiosis through the production of antibiotics, mycoparasitism through the production of cell wall lytic enzymes, production of volatile organic compounds and induced resistance are other modes of bacterial antagonist actions by which they suppress the activity of postharvest pathogens.

利用附生细菌拮抗剂管理甜椒和其他新鲜农产品的收获后病害——一种可行的选择

摘要 甜椒和其他新鲜农产品的收获后损失是全世界的主要挑战。控制这些有价值的农产品的损失主要基于合成杀菌剂的使用。然而，人们对这些化学品对环境和人类健康的影响表示担忧。因此，呼吁更安全和环保的替代品。在各种生物替代品中，细菌拮抗菌株的使用在全球范围内变得流行。细菌拮抗剂现在可以控制许多收获后病原体。微生物拮抗剂抑制收获后病原体生长的几种作用模式已被提出。然而，人们对收获的农产品上微生物群落的整体多样性知之甚少。以及这些社区如何作为收获后生物防治研究的基础。对营养和空间的竞争是细菌拮抗剂最广泛接受的作用机制。此外，通过产生抗生素产生的抗菌作用、通过产生细胞壁裂解酶产生的真菌寄生、产生挥发性有机化合物和诱导抗性是细菌拮抗剂作用的其他方式，它们通过这些方式抑制收获后病原体的活性。
