Extract

Previous work has shown that the biohydrogenation of fatty acids is different in solid and liquid fractions prepared from rumen fluid (Dorel et al. , 2005). This study aimed to relate this observation to differences in the microbial population in the different fractions. Molecular techniques allow the rapid investigation of microbial numbers and diversity in environmental samples. However, description of the microbial diversity can be affected by the efficiency of DNA extraction from samples as it is known that it is harder to quantitatively extract DNA from some microbes than others (Clement and Kitts, 2000). The aim of this study was to investigate different protocols for preparing samples and extracting DNA from different fractions of rumen fluid, in terms of both the numbers and diversity of bacteria that could be recovered.
