| Abstract | ||
| ABSTRACT Two isolates Staphylococcus aureus and Escherichia coli were used in this study, Results showed that bacteria treated with 100 mM Trehalose was able to preserved S.aureus from drying for one month in room temperature, while no effect was observed in the Trehalose treated E.coli. Results also indicated that Trehalose preservative effects were for month. The survival percentage of S.aureus treated with Trehalose after 1 month was 67% compared with the control 30%, while the results of E.coli was 66% compared with the control 32%. Results also indicated that Trehalose can protect the lyophilized bacteria stored in room Temperature for 4 months. The percentage of the viable cells of bacteria was 27% compared with the control 2%. Results also revealed that the protective effects of Trehalose reduced the lethal effects of UV Irradiation. Results indicated that S.aureus treated with Trehalose was more resistance to Tetracycline, Gentamycin, Erythromycin and Norfoxacin, Antibiotics in comparison with the control treatment, while no effect was indicated in the trehalose treated E.coli resistance ability to these antibiotics. | ||
