In order to examine the importance of the microbial composition on these effects, a panel of quantitative PCR (qPCR) primers for major groups of the microbiota, which account for up to 90% of the total cells, was employed (32,44). Louis P, Flint HJ. A 400 μl aliquot of each upper aqueous phase was transferred to a new tube; 100 μl pyridine and 80 μl isobutanol was added; and the volume of each sample was adjusted to 650 μl by adding ultra-pure water.

J Crohns Colitis. The major SCFA found in the stool samples were acetate, propionate, butyrate, and valerate as well as iso‐valerate and iso‐butyrate (Table 2). Naive Bayesian classifier for rapid assignment of rRNA sequences into the new bacterial taxonomy.

Supplementary Table S4. Fecal microbiota transplantation: in perspective. Nature. miRNAs, secreted by intestinal epithelial cells, are detected in stool and play a role in crosstalk between microbiota and their hosts [35, 36].

The working volume of each vessel was 235 mL and the growth medium feed was set to a retention time of 21 hours. 2017;389(10075):1218–28.
