SUMMARY: Solutions containing pectic materials were digested by solutions from cultures of 25 bacteria and examined chromatographically for breakdown products. Galacturonic acid and oligo-uronides were found with soft-rot Erwinia spp., Xan- thomonas campestris, Pseudomonas marginalis, Bacillus polymyxa and Klebsiella aerogenes (galacturonic acid only).
