What the literature leaves open

  • The microbial mechanisms of bio-drying are complex and remain poorly understood. There is a lack of understanding of the effect of adding exogenous microorganisms on the ecological network during the bio-drying process. The study aims to address this gap by investigating the changes in the microbial network during the bio-drying process.
