Abstract: The objective of the present study was to investigate the biodegradation capacity of endophytic organisms isolated from Oryza sativa shoots on industrial effluent. A comparative analysis was done on coir and sugar mill effluent. Physico-chemical parameters and microbial screening were conducted. The endophytic organisms were isolated from shoots in flowering stages of Oryza sativa–both bacteria and fungi–which were co-cultured for a period of 10 days. After the biofilm formation they were introduced into the coir and sugar mill effluents and the physico-chemical parameters were analysed. The results from this study indicate that there was reduction in BOD, COD, chloride, sulphide, calcium, magnesium, sodium and potassium in coir effluent and pronounced decrease in sugar mill effluent which was found to be proved statistically significant. The endophytic organisms were identified by morphological and biochemical parameters and further confirmed with RAPD analysis.
