Rezumat

15 strains bacteria and 3 strains yeasts are investigated for their ability to treat goose down washing wastewater. Bacterial strains 2, 3.1LBG, 3.2 LBG, 3.3LBG, 3.4LBG, 3.1.MRS, 3.2MRS, 3.3MRS, 3.5MRS, 3.7MRS, 4, 5, 7, 8 and yeast strain Y are isolated from soil, strain Micrococus 2 – from raw dried meat products. Yeast strains C1 and C2 are provided from yeast strains’ collection. Bacterial strains 2, 3.4LBG and 3.7LBG are non-spore forming long rods, while strains 3.1LBG, 3.2 LBG, 3.3LBG, 3.1.MRS, 3.2MRS, 3.3MRS, 3.5MRS, 4, 5, 7, 8 - non-spore forming short rods. Analyses are carried out with preliminary flocculated and filtered goose down washing wastewater. It was found that yeast strains show higher purification degree of goose down washing wastewater than bacterial strains. Short rods treat wastewater with 27, 24 % more effectively that long rods. From yeast strains C1 has highest purification degree – 28,53 %, and from bacterial strains – MRS 3.3 – 25,58%.
