abscisic acid (ABA) and salicylic acid (SA), are involved in heavy metal stress signaling in plants. In various plants, ABA and SA levels are increased with Cd stress; however, they can also increase Ni resistance [35–38]. Together with the plant defense system, plant growth-promoting endophytes (PGPEs) also play

These acids work as good chelating agents, so they become polymerised with sugarcane bagasse because it increases the number of chelating sites and helps in heavy metal removal from wastewater. Garg et al. used succinic acid for modification of sugarcane bagasse and reported 92% removal obtained at an optimum pH of 2.
