中文摘要:
      研究气调包装中华鳖贮藏过程中微生物菌相变化,为中华鳖贮藏保鲜提供参考。采用宏基因组学法研究气调包装(50%CO2 / 50%N2,3 mL∶1 g)的中华鳖4 ℃贮藏过程中的菌相变化,结果表明:整个贮藏过程中,气调包装样品的群落丰富度逐渐上升,物种多样性呈先上升后下降趋势;气调包装的优势腐败菌属为希瓦氏菌属,在贮藏末期占29.68%;气调包装能有效抑制假单胞菌属、黄杆菌属等水产品中常见的腐败微生物,维持产品新鲜品质,是中华鳖包装贮藏的优良选择。
英文摘要:
      The present study aims to reveal bacterial diversity changes of modified atmosphere packaging Chinese soft-shelled turtle, so as to provide reference for the preservation. The composition and diversity in bacterial communities in modified atmosphere packaging(50%CO2 / 50%N2,3mL∶1g) Chinese soft-shelled turtle during chilled storage (4 ℃) were investigated,using metagenomic approach. Results indicated that during the storage, the richness of microbial community went up gradually, while the diversity of microbial community incresed at first then decreased significantly; the dominant spoilage bacterias was Shewanella (29.68%). It was proved that modified atmosphere packaging could effectively inhibit the growth of spoilage microorganism (Pseudomonas, Flavobacterium). Modified atmosphere packaging was a good choice for Chinese soft-shelled turtle preservation.
