Summary: Electropherograms of soluble protein from 43 Zymomonas strains were compared, visually and by a quantitative computer-assisted clustering technique. Experimental conditions and mathematical procedures were explored to increase the reproducibility as much as possible. All isolates from British deteriorated beer samples, and from fermenting plant saps from Zare, Mexico and Indonesia had very similar electrophoretic protein patterns. There was no noticeable difference between Zymomonas mobilis and Z. anaerobia. The protein pattern of the only available strain of Z. anaerobia subsp. pomaceae was different.
