Fig. 1From: Bacterial diversity associated with volatile compound accumulation in pit mud of Chinese strong-flavor baijiu pitPCR-DGGE fingerprints based on 16 S rRNA genes amplified from bacteria found in pit mud samples collected from different positions within the fermentation pit. Lanes U, M, D, and B respectively correspond to pit mud samples from the upper wall, middle wall, lower wall, and bottom layers of the cellar. Bands marked by numbers were excised for sequencing, with the resultant alignment results being compiled in Table 2Back to article page
