(A) A 24 h old culture of Pseudomonas aeruginosa RTE4 grown on Luria agar. (B) Phylogenetic tree based on the 16S rRNA gene sequences, showing the relationship between the strain RTE4 and other members of the genus Pseudomonas. The tree was reconstructed by the neighbor-joining method using the Kimura 2-parameter method (rooted with Oblitimonas alkaliphile B4199T as an outgroup). Bootstrap values (expressed as percentages of 1,000 replications) above 50% are shown at branch points. Bar, 0.005 substitutions per nucleotide position. (C) Protease activity of RTE4 on skim milk agar plate. (D) Cellulase activity of RTE4 on cellulose Congo red agar plate. Clear halo around spot inoculated RTE4 is an indicative of cellulose production by RTE4.
