Abstract

East coast of Algeria suffers from several types of pollution, mainly hydrocarbons. The hydrocar-bon-based bacteria of the littoral were investigated. 53 indigenous strains were isolated, identified according to morphological and biochemical nature. Dietzia sp. CNJ898 PLO4 and Vibrio alginolyticus PB-WC 11099 were selected for growth tests in the presence of monoaromatic hydrocarbons as a sole source of carbon and energy and total hydrocarbons at the end of growth. The results showed that both strains used monoaromatics to grow. The total hydrocarbons determined after growth showed that all monoaromatics were biodegraded with different rates. The maximum rate was obtained with Dietzia sp. in the presence of xylene with 4.33 mg C/dm 3 at the end of the process, followed by toluene with a level of 5.07 mg C/dm 3 and 5.60 mg C/dm 3 in the presence of Vibrio alginolyticus . The lowest degradation rate was obtained in the presence of benzene with Dietzia sp. with 15 mg C/dm 3 compared to the control, which was 27 mg C/dm 3 at the beginning of growth. The results obtained showed that both selected strains assimilated the monoaromatics tested and could be used for the bioremediation of the polluted littoral.

从阿尔及利亚东海岸分离的原生细菌溶藻弧菌和Dietzia sp.在单芳烃存在下的生长

阿尔及利亚东海岸遭受几种类型的污染，主要是碳氢化合物。对浅海中烃基细菌进行了研究。分离得到53株本地菌株，经形态学和生化性质鉴定。选择Dietzia sp. CNJ898 PLO4和alginolyticus Vibrio PB-WC 11099在单芳香烃存在的情况下进行生长试验，单芳香烃是生长结束时碳和能量和总碳氢化合物的唯一来源。结果表明，两种菌株均利用单芳香剂生长。生长后测定的总烃表明，所有的单芳烃都以不同的速率被生物降解。以Dietzia sp在二甲苯(4.33 mg C/dm)存在下的反应速率最高，其次是甲苯(5.07 mg C/dm)和溶藻弧菌(5.60 mg C/dm)存在下的反应速率。在苯存在下，Dietzia sp.的降解率最低，浓度为15 mg C/dm 3，而对照在生长初期为27 mg C/dm 3。结果表明，所选菌株均能吸收所测单芳烃，可用于污染沿岸的生物修复。
