Diversity and Characterization of the Bacterial Communities of Different Water Resources in Egypt Concerning Contamination Type

The habitat of microorganisms is different from one to another, some are naturally found in water environment, others introduced due sources contamination. present study aimed characterize the bacterial community diverse resources Egypt relation contamination source pursued them. So, samples were collected seven resources; groundwater, Nile River water, agricultural drainage (El-Hussieniya drain), sewage contaminated drain (Bahr El-Baqr industrial wastes (Al-Khadrawiya fresh Lake (Nasser Lake) and brackish (Qaroun Lake). A total 2218 isolates collected, purified identified by means biochemical reactions 16S rDNA sequence analysis 21 genera. drain) has highest community, while (Nasser) lowest lake  In addition, Bacillus, Pseudomonas Staphyllococcus most popular genera, where they have been detected all types resources. less genera Yersinia, Klebsiella, Aerumonas, Shigella, Salmonella, Cardiobacterium, Arthrobacter Streptobacillus, once.
