Abstract
Heat or ethanol shock of Zymomonas mobilis enhanced the labeling by [35S]methionine of several polypeptides and induced the synthesis of a new polypeptide (molecular weight, 18,500) associated with the envelope fraction. These results indicate the existence of a typical heat-shock response in Z. mobilis. This response could be involved in the induction of increased ethanol tolerance in Z. mobilis cells.
