BIOREMEDIATION OF AGRICULTURE WASTEWATER USING SOME PLANT GROWTH PROMOTING RHIZOBACTERIA AND ITS REUSE FOR IRRIGATION OF SOME CROPS

Abstract

This work was conducted to study the ability of PGPRs strains to treat the agricultural drainage wastewater from El Mohete drain (Marioteya Canal) for irrigation the Mentha viridis cv. and Gladiolas grandiflorus cv. plants. Studied were focused on: 1-Collectingsamples from different places and different depth levels (summer and winter). 2-Determination of the morphological, chemical and microbiological properties of the water. 3-Counting, isolation and identification of pathogenic bacteria isolates (morphology- physiology- chemically) after each stage of sampling. 4-Determination rates of all the dominant of microbial group. 5-Determination of morphological and chemical properties of contaminated water compared to non-polluting on salinity, acidity, alkalinity, heavy metals, pesticides and nitrate nitrogen component. 6-Studying the ability to remove the pollution using some of (PGPRs) strains e.g. Bacillus megaterium , Bacillus subtillus , Bacillus circulans, Paenibacillus polymyxa , Pseudomonas fluorescens , Serratia sp. and Azotobacter sp. Azotobacter chroococcumAzo.5, Azo.9 and Azo.23 to treat the drainage water for irrigation of the Ment and Gladiolas plant . a-Studying the optimization of heavy metals removal by (PGPRs). b-Studying the ability of pesticides degradation by (PGPRs).
