Figure 1From: Single-step ethanol production from lignocellulose using novel extremely thermophilic bacteriaPhylogenetic tree of Caldicellulosiruptor strains. Neighbor-joining tree based on 16S rRNA gene sequence comparisons of isolated Caldicellulosiruptor sp. strains and selected bacteria. Bootstrap values are based on 1,000 replicates. The scale bar represents 0.01 changes per nucleotide position. GenBank accession numbers are given in parentheses. T, type strain.Back to article page
