[Screening and identification of GABA-producing microbes in fermentation process of Sojae Semen Praeparatum].

A high-content GABA was found in Sojae Semen Praeparatum(SSP), which is a famous traditional Chinese medicine and officially listed in Chinese Pharmacopoeia. To screen out and identify GABA-producing microbes from samples at different time points during the fermenting process of SSP, traditional microbiological methods combined with molecular biological methods were used to study the predominant GABA-producing microorganisms existing in the fermenting process of SSP. This study would lay a foundation for further studying the processing mechanism of SSP.

[Identification of dominant microbes from traditional Chinese medicine Pinelliae Rhizoma Fermentata].

To investigate the microbial species, amount changes as well as the isolation and identification of domain strains at different fermentation time points of Pinelliae Rhizoma Fermentata, and provide basis for exploring the mechanism of Pinelliae Rhizoma Fermentata processing. Five samples were chosen at the time points (0, 18, 36, 54, 72 h) of Pinelliae Rhizoma Fermentata processing. Bacteria, mold and yeast from the samples were cultured; their colonies were counted, and the dominant strains were isolated and purified.
