SummaryA flocculent, high ethanol-producing strain ofZymomonas mobilis subsp.mobilis was isolated from spontaneously-fermenting sugar-cane juice. Cells collected during the stationary growth phase of a culture in sucrose based medium, were examined in thin section by electron microscopy and showed elongated crystalloid cytoplasmic structures, resembling eukaryote peroxisomes, but devoid of an external membrane. These structures have not been previously described inZymomonas. The formation of vesicles from an external membrane as well as zones of lysis were also observed. General considerations on the unusual structures are discussed in this report as well as their possible relationship between ethanol, sugar concentration and growth phases of the culture.RésuméUne souche floculante deZymomonas mobilis subsp.mobilis a été isolée du jus de canne à sucre fermentée par sa flore microbienne naturelle. L'observation de coupes minces de cellules récoltées pendant la phase stationnaire, développées sur un milieu de culture avec saccharose, observés au microscope electronique on montré structures cytoplasmiques cristalloïdes allongées semblables aux peroxisomes des cellules eucaryotes, mais dépourvues d'une membrane extérieur. Ces structures n'ont pas été descriptes chezsZymomonas. En plus on a vu la formation de vésicules à partir de la membrane extérieur et aussi des zones de lyse. On discutés dans le travail considerations générales sur ces structures inhabituelles et aussi sa possible rélation parmi concentration d'ethanol, sucre et la phase de croissance des cultures.
