Characterization and application of polysaccharides produced by Pseudomonas atacamensis M7D1 for chromium (III) removal from tannery effluent.

The wastewater from various industries contaminated with heavy metals poses significant environmental challenges. Biosorption has emerged as a widely used method for removing heavy metals from industrial wastewater. Pseudomonas atacamensis M7D1 is known to produce polysaccharides, but the potential of its polysaccharides as an adsorbent for heavy metal removal still needs to be explored.

Exploring biosynthesis strategies to boost the yield of exopolysaccharide-protein blend from Bacillus arachidis SY8(T), an isolated native strain, as a potent adsorbent for heavy metals removal.

This investigation centers on the synthesis of a polysaccharide-protein blend produced by an isolated native strain (99.12 % phylogenetic affinity with Bacillus arachidis SY8(T)). The primary objective was to investigate the production of extracellular polymeric substances (EPS) under diverse stress conditions, encompassing exposure to heavy metal ions, salt, and toxic agents.
