Evaluation of the ability of Micrococcus sp. isolated from Barada river to biodegradation of vegetable oil wastes

Alsulaiman A., . and Ali Nizam A., . Evaluation of the ability of Micrococcus sp. isolated from Barada river to biodegradation of vegetable oil wastes. pp. 345-350. ISSN 2231-7546

Fifty six strains of Micrococcus sp. were isolated from the water samples from Barada River in Damascus. Ten isolates of Micrococcus sp. species were taken for the present study for investigate biodegradation ability of vegetable oil wastes under the influence of this genus. The vegetable oil wastes dependent growths of these isolates were assessed for 15 days by monitoring the gradient fluxes in pH optical density OD and total viable count TVC in the medium. Results showed an increase in OD and TVC as well as fluctuations in pH values. The relationship between these values was studied and determined if the relationships were statistically significant and values were compared with the results in the positive control to the same strain. Biodegradation activity of different Micrococcus sp. species was tested in vegetable oil wastes which showed a good activity with 1 concentration of vegetable oil wastes but decreased in 2 and 3 concentration. The genus Micrococcus sp. showed a good ability to grow in different concentrations of vegetable oil wastes that refers to the ability of the genus to use vegetable oil wastes as the only carbon source.

Abstract

Fifty six strains of Micrococcus sp. were isolated from the water samples from Barada River in Damascus. Ten isolates of Micrococcus sp. species were taken for the present study for investigate biodegradation ability of vegetable oil wastes under the influence of this genus. The vegetable oil wastes dependent growths of these isolates were assessed for 15 days by monitoring the gradient fluxes in pH optical density OD and total viable count TVC in the medium. Results showed an increase in OD and TVC as well as fluctuations in pH values. The relationship between these values was studied and determined if the relationships were statistically significant and values were compared with the results in the positive control to the same strain. Biodegradation activity of different Micrococcus sp. species was tested in vegetable oil wastes which showed a good activity with 1 concentration of vegetable oil wastes but decreased in 2 and 3 concentration. The genus Micrococcus sp. showed a good ability to grow in different concentrations of vegetable oil wastes that refers to the ability of the genus to use vegetable oil wastes as the only carbon source.
