Abstract
From two sites at each of El-Rahawi and Belbeis agriculture drains located at Nile Delta as well as from river Nile, one surface water sample from each was collected, and their indigenous microbial intensities were estimated. The studied indigenous microorganisms included total bacteria, total fungi, Azotobacter sp., Clostridium sp., Pseudomonas sp., phosphate dissolving bacteria and cellulose decomposers. Results revealed that the counts of bacteria, fungi, Azotobacter sp < em>., Clostridium sp., Pseudomonas sp., phosphate dissolving bacteria and cellulose decomposers were 93x106, 1x106, 1x103, 6x106, 27x106, 1x106, 2x106 and 18x106, 2x106, 1x104, 7x106, 25x106, 25x106, 2x106 respectively at El-hod and El-hadar sites at El-Rahawi agriculture drain. Whereas, the counts of bacteria, fungi, Azotobacter sp., Clostridium sp., Pseudomonas sp., phosphate dissolving bacteria and cellulose decomposers were within the range of 62x106, 1x106, 1x102, 30x106, 20x106, 1x106 and 7x106 and of 50x106, 2x106, 1x104, 79x107, 6x106, 88x106 and 75x106 respectively at the Bridge and Mosque sites at Belbeis agriculture drain. However, the counts of bacteria, fungi, Azotobacter sp < em>., Clostridium sp.,Pseudomonas sp., phosphate dissolving bacteria and cellulose decomposers were within the range of 57x106, 2x104, 1x102, 45x106, 7x106, 1x106 and 2x106 respectively in River Nile water. The functions of the studied indigenous biotas existing in drainage water and soil ecosystem and crops are discussed.
