Researchers seek a more renewable and natural alternative for water soluble anionic polyacrylamide (PAM), a highly-effective, petroleum-derived polymer used in agriculture to control erosion and reduce water seepage from unlined irrigation structures. This study evaluated four anionic polymers including low-(0.5 Mg mol-1) or high molecular-weight (MW) (10-20 Mg mol-1), bacteria-produced…,Polyacrylamide and biopolymer effects on flocculation … ,Biofilms may affect the soil structure stability and functioning as they are constituted by the extracellular polymeric matrix that may work as a flocculating agent or protective surface coating…,Polyacrylamide and biopolymer effects on flocculation … ,After 140 h, the biopolymer reduced seepage loss rates by 21%, while PAM increased loss rates 1.6-fold, compared to controls. These data suggest that the biopolymer would be less effective than PAM for reducing water erosion owing to its lesser flocculation and aggregate-stabilizing potential.
