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.
