Standard Methods for the Examination of Water and Wastewater

This was carried out using procedures which have been previously reported. This was carried out according to previously reported methods. Characterisation and Identification of Organisms The identification of bacteria was based on biochemical characterizations including citrase, urease, catalase, indole, raffinose, xylose, galactose, starch hydrolyses, and oxidase reaction.

The macroscopic colonial appearances of fungal growth in plates were observed and recorded. The macroscopic examinations were based on colony texture, size, pigmentation, time of growth, color on the reverse side of the plate and colony margin.

The preparation was covered with a cover slip.

Observed characteristics were recorded and compared with the established identification keys as previously described. Then, mL of the effluents was dispensed into mL flasks, the pH of the medium was adjusted to 7.

The autoclaved flask was inoculated with 1 mL of bacteria inoculum of the microorganism and the flask was incubated for 21 days. The pH was recorded every 48 hours. Fungi Mineral salt medium prepared with the following composition was used for the studies: disodium phosphate 1.

Then, mL of the effluents was dispensed into mL flasks, the pH of the medium was adjusted to 5. The fungi plate was emulsified with 10 mL of sterilized distilled water, and then 1 mL of the fungal inoculum was inoculated into each autoclaved flask.
