| Abstract | ||
| The effeciency of ethanolic extract of Nostoc linkia algae has been tested in reducing three species of bacteria Escherichia coli , Pseudomonas aeruginosa and Staphylococcus aureus which isolated from contamination water in Laboratory conditions 37 ْ C in period treatment 72 hour in different concentration (0.25 , 0.5 , 0.75 , 1 mg/l ). It became obvious that the ethanolic extract of Nostoc linkia algae has high effeciency in reducing different bacterial number in removing ratio 98.9% after 72 hour . in concentrate 1 mg/l for bacteriaa Escherichia coli and 94.6, 75.3% in concentrate 1 and 0.75 mg/l respectivelly for bacteria Pseudomonas aeruginosa and 94.7, 80.1% in concentrate 1 and 0.75 mg/l respectivelly for bacteria Staphylococcus aureus . associated with different significant for two concentrate 1 and 0.75 mg/l . The total bacterial number reducing in removing ratio 90.8% in concentrate 1 mg/l of ethanolic extract of Nostoc linkia algae after 24 hour of experiment. | ||
