摘要
该文研究酱香型白酒及不同质量浓度大鲵皮肤泡制的酱香型白酒(MSAS)对肠道微生物的影响,以优化大鲵皮肤泡制浓度。采用实时荧光定量PCR(RT-PCR)方法测定肠道菌群数量。结果表明:6.25 g/L及12.50 g/L的MSAS,与空白对照组相比可显著(P<0.05)增加肠道乳杆菌(Lactobacillus)数量,维持(P>0.05)肠道脆弱拟杆菌(Bacteroides fragilis)数量,且与空白及白酒组相比可显著(P<0.05)降低大肠杆菌(Escherichia coli)数量;与白酒组相比,除25.00 g/L以外的MSAS组可显著(P<0.05)改善白酒对双歧杆菌(Bifidobacterium)、厚壁菌门(Firmicutes)、拟杆菌门(Bacteroidetes)及总肠道菌群的抑制作用,且12.50 g/L组厚壁菌门/拟杆菌门高于其他处理组,更有利于肠道菌群平衡。6.25 g/L及12.50 g/L的MSAS有进一步研究的意义。
The effect of Moutai-flavor Baijiu (liquor)(MB) and Moutai-flavor soaking spirit containing different amounts of Andrias davidianus skin (MSAS) (3.125 g/L, 6.25 g/L, 12.50 g/L, 25.00 g/L) on mouse intestinal microflora was investigated to optimize the soaking concentration of A. davidianus skin. Real Time-PCR method was used to determine the composition of the intestinal microflora. The results showed that Lactobacillus count increased significantly (P<0.05) in 6.25 g/L and 12.50 g/L MSAS groups, Bacteroides fragilis count maintained (P>0.05), and Escherichia coli count decreased in mouse gut in comparison with the control group. The inhibitory effect of MB on Bifidobacterium, Firmicutes, Bacteroidetes and total intestinal flora reduced significantly (P<0.05) in mouse guts in MSAS groups (except 25.00 g/L) in comparison with the MS group. In addition, the ratio of Firmicutes/Bacteroides in 12.50 g/L MSAS group was higher than that in other treatment groups, which indicated this treatment was more conducive to the balance of intestinal flora. MSAS with 6.25 g/L and 12.50 g/L were suggested to be applied for further studies.
