Abstract
Malachite green, a water-soluble dye is considered be an efficient dye that has its usage in various fields be in textile or in medical or in pharmaceutics. The dye has been reported to cause health hazard thus the effluent with such a dye demands proper treatment. But, the fate of such dye treated water is also another concern in the recent times. In this study, the toxicity of such dye was analyzed on Vigna radiata(moong) plant on the basis of radical and plumule growth and percent germination. A comparison of the above parameters was done with dye, wheat bran treated, acid and alkali modified wheat bran treated dye and also by organism (Schizophyllum- S4) treated dye on the plant. The study has revealed that there was 100% germination of seeds under all the conditions, with 10% and 12.3% increase in radical and plumule growth by Schizophyllum-S4, a white rot fungus, treated dye (initial concentration 100mg/L) after an incubation period of 10 days but has shown a better result with alkali treated wheat bran as an adsorbent with around 15% and 11.7% increase in the radicle and plumule growth with 23% and 48% increase in chlorophyll a and chlorophyll b, respectively in comparison to the control (plant without aqueous solution of dye)under the same conditions applied.
