Judgement of the National Green Tribunal (Southern Zone, Chennai) in the matter of NGI Action Council Vs Nitta Gelatin Inc. & Others dated 27/02/2017 regarding pollution caused by the industry Nitta Gelatin India Ltd. It is contended that the industry releases everyday 25.08 tonnes of chlorides and 43.89 tonnes of total dissolved solids (TDS) into the Chalakkudy river along with other chemical and industrial effluents.
Petroleum hydrocarbons (PHCs) are among the most prevalent sources of environmental contamination. It has been hypothesized that plant root exudation of low molecular weight organic acid anions (carboxylates) may aid degradation of PHCs by stimulating heterotrophic microbial activity. To test their potential implication for bioremediation, we applied two commonly exuded carboxylates (citrate and malonate) to uncontaminated and diesel-contaminated microcosms (10 000 mg kg−1; aged 40 days) and determined their impact on the microbial community and PHC degradation.
