| Abstract | ||
| SIX LOCALITIES along the Suez freshwater canal were studied. ……The characterization of water quality included physical, biochemical and microbiological analyses. The obtained results showed that the maximum turbidity was recorded at Abu Atwa station (70 NTU), while maximum electrical conductivity (EC) were recorded at two sites, Suez water station and Amir village (633 and 607 μS/cm). Results also indicated high level in the organic load represented by an increase in the biological oxygen demand (BOD) and chemical oxygen demand (COD) above the permissible levels at Amir village and Abu Atwa sites, while slight increase in (COD) was observed at Kobry El Saal and Sarabium water station. The total viable bacterial count (TVB) ranged from 4.7× 102 to 20.2×102 cfu/ml, which greatly exceeded the permissible levels also the fecal coliform and fecal streptococci were detected in all investigated sites. The isolation of actinomycetes from Suez fresh water canal sediments by enrichment culture technique resulted in two isolates (N1 and N2) using DDT enrichment technique. The isolate N2 showed weak results in biodegradation of selected hydrocarbons, while N1 showed much more activity, so its identification was confirmed by phylogenic analyses and selected for further investigation. Conclusion, the water characteristics demonstrated water quality deterioration especially in the Amir village which may be due to industrial and domestic wastewater from human and agriculture activities. | ||
