Abstract: A series of streptococcus strains were primailys screened by sensory evaluation the susceptibility to synerssis, thewater holding capacity and aparent viscosity of the yoghurt and were determined. The yoghurt made from mixed cultivation ofthe two strains was better than the yoghurt made from contrasting strains and market yoghurt. By using electron microscope, thebacillus was determined as film forming stram and the streptococcus a ropy strain.

Key words: sliming yoghurt lactic acid bacteria, exopolysaccharides, susceptibility to syneresis, apparent viscosity
