Abstract. For the first time, we present a cytomorphological description of self-healing (repair) process damaged thalli sites, wound healing , in green filamentous algae, Ulothrix zonata (F. Weber & Mohr) K tzing 1833. In filaments this species from Lake Baikal and Angara (Baikal outflow), Zhilishche inflow) Ida (Angara rivers, light microscopy methods revealed dome-like conical protrusion...

Method for production and regeneration of Acetobacter pasterianus protoplasts is described. The protoplasts were obtained by treatment of cells with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplast formation was obtained in protoplast buffer with NaCl (0.5M) as ...

Protoplast wet densities (1.315 to 1.400 g/ml), determined by buoyant density sedimentation in Metrizamide gradients, were correlated inversely with the protoplast water contents (26.4 to 55.0 g of water/100 g of wet protoplast) of nine diverse types of pure lysozyme-sensitive dormant bacterial spores. The correlation equation provided a precise method for obtaining the protoplast water content...
