Abstract

Abstract This study demonstrates the potential application of a portable 3D‐printed sensor to monitor microbial growth during soil bioremediation. Bacillus subtilis , a commonly found soil microorganism, is used to evaluate its growth characteristics. The integration of real‐time oxidation–reduction potential (ORP) reading and voltage output allows for a better illustration of microbial growth, with a focus on the mid‐exponential growth phase. This new technology can potentially increase the efficiency of soil bioremediation techniques by providing a better understanding of the microbial interactions and growth patterns involved.

Key findings

  • The sensor effectively monitors microbial growth, particularly during the mid-exponential growth phase.
  • The integration of ORP and voltage output provides a better understanding of microbial interactions and growth patterns.
  • The technology has potential to increase the efficiency of soil bioremediation techniques.
