Introduction of Microbial Biopolymers in Soil Treatment

Polyacrylamide (PAM) is a simple linear- or cross-linked polymer synthesized by acrylamide (i.e., CH 2 CHCONH 2) subunits, which are non-toxic and hydrophilic . Anionic polyacrylamide (PAM) has negative charge density and induces electrostatic bonding with clay particles [36,37], which results in reduced soil erosion and runoff control .
