Most isolates recovered from marine environments are Gram‐negative proteobacteria, even with the use of various media and media additions to enhance recoverability. Cultivation studies with two genera of deep‐water sponges yielded nine isolates that demonstrated bulbous branching rod morphology, which is usually associated with microorganisms staining Gram‐positive. Gram reactions indicated that the isolates were Gram‐negative, which was confirmed by partial 16S rDNA sequencing. All nine isolates were shown to be α‐proteobacteria most closely related to other α‐proteobacteria isolated from various sponges.
