The biotechnological potential of bacterial extracellular polymeric substances in lead biosorption.

ABSTRACT:

Introduction

Extracellular polymeric substances are composed of a diverse range of functional groups, thereby making a strong case for their consideration as biosorbents in heavy metal bioremediation. This study, therefore, assessed strategies to enhance the biotechnological potential of extracellular polymeric substances produced by an endophytic bacterium, Bacillus MHSD_36.

Methods

Design of experiments were used to optimize the yield of extracellular polymeric substances from Bacillus MHSD_36. A mixture design was subsequently used to develop a cocktail of EPS and hydrophobicity components for the optimal biosorption of lead.

Results

The production of the EPS, from MHSD_36, was optimized through lead induction at a concentration and time of 5.23 mg/L
