AbstractThe morphology of poorly known freshwater amoebae, Saccamoeba wellneri Siemensma, 1987 and Saccamoeba limna Bovee, 1972, were investigated using living observations at light microscopic level. S. wellneri was collected from Karloveské rameno branch of the Danube River and Štrkovecké jazero lake in Bratislava, Slovakia. Its locomotive form is typical with crescent-shaped and bipyramidal crystals and uroid with short wart-like papillae. S. limna was found in an indoor freshwater aquarium in Bratislava, Slovakia. The locomotive form of S. limna has broad monopodial shape and possesses typical hyaline uroid with short nonadhesive filaments. Many small bipyramidal crystals were noted. Additional data and details on the morphology of both species were described and illustrated and re-diagnoses are presented. This paper is helpful for their identification on the base of locomotive morphology, floating, and resting forms and allows distinguishing S. wellneri and S. limna from other hartmannellids at light microscopic level.

To identify the cellular forms that are responsible for the synthesis of pullulan produced by Aureobasidium pullulans, we performed cytochemical and ultrastructural localizations of glucan in the cellular forms of this microorganism (blastospores and resting forms). Growth conditions, cell populations, and pullulan production were studied concurrently. Our results are consistent with a model in which the resting forms (swollen cells and chlamydospores) might be primarily involved in this extracellular polysaccharide elaboration. At the cellular level, pullulan production could be the result of three main stages: (i) cell wall thickening and extracellular polysaccharide synthesis by the swollen cell, (ii) fibrillar arrangement of this polysaccharide into pullulan along a capsular network around the chlamydospore, and (iii) subcellular hydrolysis separating the capsule from the periplasmic zone and consequently permitting the solubilization of pullulan in the culture medium. A melanization process in the outer layer of the cell wall and the capsule accompanies these patterns.Key words: Aureobasidium pullulans, capsule, cytochemistry, polysaccharide, pullulan, resting forms.
