STUDY OF SOME BACTERIAL POLLUTANUTS IN EUPHRATES WATER AND THE LAKES OF THERTHER AND HABBANIAH

Abstract

ABSTRACT:This research included a study about the pollution of environment that out came frompublic efficiencies and humanity activities on the quality and context of Euphrates river from the Ramadientrance city to its end in Falluja city involving Habbanyah and Therthar lakes. This study included somebacterial pollution involving the Total Plate Count of the aerobic microbes in addition to isolation andidentification of some bacteria that present in the Euphrates river and Habbanyah and Therthar lakes andDissolved Oxygen and the rate of Biological Oxygen Demand. The results have shown an averageallowable values of dissolved oxygen were (7.7) mg/L and (4.67) mg/L the biological oxygen demandwhich was exceeded the allowable values average.Microbial study showed that the total aerobic bacteria which have recorded different results as itreached aminimum levels in some sites (F1 station (70 CCm3) and maximum levels in others (F2 station)(314×104 CCm3). The results of isolation and identification of bacteria have shown the presence of thefollwing genera :Enterobacter (24%) ،Klebsiella Pneumoniae (17.6 % ) ،Pseudomonas spp (16.2%) ،Citrobacter (12.5%) ، Escherichia coli (12.1%) ،Proteus mirabilis (5.5)، Salmonella spp (5%) Shigellaspp (3.7%)، Flavimonas Oryzihabitas (2.8%) . Enterobacter spp was the dominant genus compared withothers bacteria have indicated surely the organic and microbial pollutions of the Euphrates water at thestudied sites.
