The phylogeny of bacteria belonging to the genus Nitrobacter was investigated by sequencing the whole 16S rRNA gene. The average level of similarity for the three Nitrobacter strains examined was high (99.2%), and the similarity level between Nitrobacter winogradskyi and Nitrobacter sp. strain LL, which represent two different genomic species, was even(More)
Gene selection has become a common task in most gene expression studies. The objective of such research is often to identify the smallest possible set of genes that can still achieve good predictive performance. To do so, many of the recently proposed classification methods require some form of dimension-reduction of the problem which finally provide a(More)
