Differential recovery of bacterial and archaeal 16S rRNA genes from ruminal digesta in response to glycerol as cryoprotectant
Özet
Bacteria and archaea in frozen (-20 degrees C) ruminal digesta were analysed by qPCR and cloning/sequencing of 16S rRNA genes. Samples frozen with and without glycerol as cryoprotectant indicated a major loss of Bacteroidetes in unprotected samples, resulting in higher proportions of Firmicutes. Archaeal numbers and diversity were unaffected. (C) 2013 Elsevier B.V. All rights reserved.
