A Tn5 transposon mutant was isolated of the alkylphenol degrader Pseudomonas sp. KL28 that showed increased growth at higher levels of m-cresol on solid and in liquid cultures. The transposon was inserted at the 5'-terminus of rpoS, which encodes a stationary-phase sigma factor. When grown on agar plates, the rpoS mutant developed prominent wrinkles, especially at lower temperatures, and spread faster on soft agar. In addition, the rpoS mutant had enhanced biofilm-forming ability that was not due to self-produced diffusible signals.
