Abstract

The current study aimed to evaluate the phytotoxicity of tetracycline and amoxicillin on Vigna radiata and its remediation potential in hydroponic system. Germinated seeds of Vig-na radiata were planted with varying concentra-tions of tetracycline and amoxicillin (150 – 500 mg L−1) in triplicates (n=3) for three weeks. Tox-icity biomarkers, i.e. changes in plant biomass, photosynthetic pigment, phenol, flavonoid con-tent and antioxidative enzymes were estimated after completion of 3 weeks. The results illus-trated that high tetracycline concentration (500 mg L-1) in hoagland media resulted decrease in total chlorophyll content (3.045- 2.252 mg total chlorophyll /g tissue) while in case of amoxicillin, chlorophyll content was increased (5.18 - 7.309 mg total chlorophyll /g tissue). Carotenoid, Total flavonoid and phenolic content, were also sig-nificantly (p < 0.05) reduced due to toxicity of these antibiotics. Antioxidant enzyme like cata-lase showed 7.22 % degradation in their activity with highest concentration (500 mg kg-1) of tet-racycline and 27.3 % degradation was found in case of amoxicillin. Glutathione peroxidase ac-tivity was also decreased in both of the cases. Subsequently, the Vigna radiata showed 63% remediation potential with tetracycline and 93 % in case of amoxicillin. Hence, overall results indicate that, the phytoremediation rate shown by Vigna radiata is very promising and these antibiotics also showed its toxicological impact on plants.
