Abstract:

Worldwide the bioremediated textile effluent as a water source for agricultural irrigation has been introduced as an alternative for wastewater destination in the environment. Focusing on agricultural environmental aspects, the objectives of the present study was to analyse the physico-chemical parameters of textile effluent and methyl orange treated with the selected algae Oedogonium subplagiostomum AP1. To analyse the biometric parameters such as germination percentage, height (shoot and root length), vigour index, number of flowers, buds, branches, leaves, nodes, size of the flowers (cm), weight of the flower (g) and fresh weight of the test plants namely Marigold (yellow and orange) and Celosia argentea on 7th and 60th day using tap water (T1), untreated methyl orange (T2) and bioremediated methyl orange (T3) solutions respectively. The physico-chemical characteristics of the soil before and after harvest were also analysed. The degraded metabolites in bioremediated methyl orange and untreated methyl orange solution were also checked for its toxicity against the selected bacterial and fungal isolates. The results revealed that the physicochemical parameters of the textile effluent, untreated and treated methyl orange falls within the limit prescribed by BIS. The biometric parameters analysed on 7th day shows that the germination percentage was maximum in control (T1) followed by plants treated with bioremediated dye solution (T3) and minimum in untreated dye solution (T2). Similar trend was observed in all the biometric parameters tested for the selected plants on 7th and 60th day respectively. The soil parameters were found to be high in T2 treatment when compared with control (T1) and T3. The microbial toxicity shows that there was no zone of inhibition in the control and treated dye solution whereas significant inhibition was recorded in untreated dye solution. Thus the present study validates the use of bioremediated methyl orange solution as an eco-friendly alternative water source for irrigation.
