The normal microbiota in this anoxic environment are composed of bacteria, ciliate and flagellate protozoa, and anaerobic chytridiomycete fungi (Flint 1997 ; Gordon and Phillips 1998 ).Because cellulose and plant hemicellulose are the most abundant carbon and energy source in the rumen, the glycosyl hydrolases (GHs) of these organisms must play a significant role in their homeostasis.The smallest distance corresponds to the organism whose codon usage is most similar to that of the gene considered.The CAZy internet server ( was used to define the GH families (Henrissat and Bairoch 1996 ).

1995 ) which exhibits very high cellulase activity against crystalline cellulose (Wilson and Wood 1992 ) and is similar to that described for (Beguin and Lemaire 1996 ) and other bacteria (Karita, Sakka, and Ohmiya 1997 ).

As a measure of the distance between the codon usage of a gene (), we calculated the Hamming distance following a procedure similar to the one used for predicting protein structural classes (Chou and Zhang 1995 ).



In fact, one would expect that the ratio of oranges to apples would change in a very specific way over the time elapsed, since the process continues until all the apples are converted. A particular rock or mineral that contains a radioactive isotope (or radioisotope) is analyzed to determine the number of parent and daughter isotopes present, whereby the time since that mineral or rock formed is calculated.… continue reading »
