Fig. 4From: Salinity effect on the metabolic pathway and microbial function in phenanthrene degradation by a halophilic consortiumPhylogenetic trees of catabolic gene fragments obtained from clone libraries and isolated pure cultures. a Genes encoding RHDs; b genes encoding C12Os; c genes encoding C23Os; d genes encoding G12Os; e genes encoding P34O. The sequences obtained from clone libraries were separated into different OTUs with 90% identity. Each OTU was shown in red bold, with proportion shown in the brackets. The sequences of fragments obtained from isolated pure cultures were shown in black boldBack to article page
