常压低温等离子体对羊肚菌栽培基质细菌群落的影响
Effect of Low-Temperature Plasma on Bacterial Community of Morchella Cultivation Substrate
摘要
Abstract
Cultivation substrate of Agaricus Morchella was used to investigate the sterilization effect of bacteria through the low-temperature plasma technology carried out at atmospheric pressure.High-throughput sequencing technology was performed to analyze the changes of bacterial community,such as composition and diversity in the substrate,before and after treatments of low-temperature and room-temperature as well as low-temperature plasma.Our results showed that the diversity,richness and evenness of bacterial community were significantly reduced after treatment by low-temperature plasma,with the largest decrement rate up to 32%,34%and 9%,respectively.Among different families detected from the bacterial community,however,relative richness of Burkholderiaceae increased continuously after treatment while among the genera,the dominant bacterium was Aquabacterium after treatment.The bactericidal rate of low-temperature plasma treatment against a variety of pathogenic bacteria such as Streptomyces,Xanthomonas,Ochrobactrum,and Paraburkholderia was above 99%.This study,as the first time,applied the new technology by using the atmospheric low temperature plasma for substrate sterilization of Morchella,which could effectively kill a variety of pathogenic bacteria,thereafter,demonstrating a good example and prospects for the future applications of above technology to the effective sterilization and preservation of Morchella cultivation substrates.关键词
