The Bai group is one of the 15 largest Chinese ethnic minorities.However,currently only limited knowledge is available on the intestinal microbiota of the Bai population.This study profiled the fecal microbiota communities of 43 Bai people residing at the Panlong District,Xishan District,Eryuan County and Jianchuan County using the 454 pyrosequencing technique.At the phylum level,the gut microbiota of the analyzed Bai people was dominated by Firmicutes(75.92%),with a high Firmicutes to Bacteroidetes ratio(4.83%).The core gut microbiota of the Bai ethnic group primarily comprised the family Enterobacteriaceae,Lachnospiraceae,Peptostreptococcaceae,Ruminococcaceae and Veillonellaceae.Principal coordinate analysis(PCoA) based on the unweighted UniFrac distances revealed structure segregation between rural and urban residents.The relative abundance of Faecalibacterium,Roseburia,Subdoligranulum,Selenornonas,Butyricimonas,Cronobacter and Yersinia were found to be significantly higher in urban than rural,whereas the other four genera,Acetonema,Phascolarctobacterium,Barnesiella and Propionispora were significantly lower in urban than rural (p≤0.05).In conclusion,Our study revealed that the abundance and diversity of gut microbiota were different between urban and rural residents.Dietary and lifestyle factors may explain the difference.

乳酸菌噬菌体感染被认为是目前食品发酵工业最大的问题之一，因为它可能会导致发酵失败，并造成经济损失。工业生产过程中，常常采用化学试剂对员工、设备以及工厂环境进行消毒，以避免发酵过程中由于噬菌体的出现带来影响。本研究通过对三种不同培养基(MRS培养基、RSM培养基和TMG培养基)中，不同温度及处理时间对噬菌体P1的灭活效果进行研究，发现不同培养基并未对噬菌体P1表现出保护效果；90℃可使噬菌体P1瞬时
羟苯乙酯是短短芽胞杆菌FJAT-0809-GLX的主要抑菌活性物质,为提高该菌株发酵液中羟苯乙酯的产量,本研究采用响应面法对其发酵培养基成分进行优化研究.首先通过单因素试验,对发酵培养基中的碳源、氮源和无机盐进行了优化,结果表明,培养基最佳碳源、氮源和无机盐分别为DL-苹果酸、蛋白胨和NaCl.进一步,通过Plackett-Buiman设计对培养基的影响因素进行筛选,结果表明,影响显著的3个因素分
