“…Whereas, in the Powell model, other than the use of substrate for energy for the build-up of new cells (growth), the energy was also used to maintain the metabolism. The energy is utilised to sustain the life and mortality of cells by maintaining chemical reactions in the cells ( Priyadarshini et al., 2021 ; Muloiwa et al., 2020 ). In substrate inhibition condition, when the concentration of substrate exceeds the ideal values in biological system, substrate inhibition occurs, slowing the rate at which the cells develop.…”

“…On the other hand, contaminated sites with a low bioavailability index might need additional treatments to solubilise and raise up the concentrations of the contaminants in the water ( Haws et al., 2006 ). Furthermore, other than bioavailability effect, substrate inhibition, enzyme activities and terminal electron acceptor have also play a major role in remediating PAHs contaminated sites ( Priyadarshini et al., 2021 ; Mu et al., 2022 ).…”

“…first order, second order), growing organism (i.e. Monod, Logistic) and substrate-inhibition (i.e Edward, Haldene) can be used to estimate the biodegradation kinetics parameters ( Priyadarshini et al., 2021 ). The accuracy and reliability of the estimated model parameters is important to assess the prospect of remediation strategy which can save time and cost.…”

“…Phenolic wastewater frequently percolates into the soil, contaminating nearby water reservoirs, lakes, rivers, and even cropland. It was found in natural water in the range of 0.01–2.0 μg/L, whereas, in river water polluted by petrol processing plants, the concentration can approach or surpass 40 mg/L (Mohd, 2020; Priyadarshini et al., 2021).…”

The rapid growth and development of industrial sectors releases massive amounts of phenolic contaminants into the aquatic environment. Bioremediation is a long‐term and cost‐effective way of removing phenolic contaminants from the environment. The success of bioremediation depends heavily on the biomass growth, enzymatic activities of microbial communities, their interactions, and other cellular metabolic activities related to phenolic degradation. Thus, the current review paper focuses on evaluating the microbial remediation of phenolic contaminants as well as the many challenges that come with it, with special reference to: (i) uses, occurrence of phenolic pollutants, and contamination levels; (ii) factors affecting phenolic biodegradation and biomass growth, such as the effect of temperature, pH, agitation speed, carbon sources, inoculum size, and age. The nutritional requirements for improved microbial growth and biodegradation of phenolic from contaminated environments were also highlighted, with a particular emphasis on the role of culture medium components and various redox mediators in phenolic compound removal. The efficiency of phenolic biodegradation has also been compared with a number of previously described advanced oxidation processes.

In this study, a three-dimensional coupled lattice Boltzmann model and cellular automata platform was developed to simulate biofilm growth and phenol biodegradation as an effective and sustainable way to remove phenolic contaminants in aquatic systems. Two three-dimensional bioreactors with cubic or spherical obstacles at varying inlet phenol concentrations and flow velocities were examined. The results showed that the cubic-bioreactor had higher phenol reduction than the sphericbioreactor due to the greater effects of cubic obstacles on flow patterns. The biofilm concentration in bioreactors decreased up to 36.4% as inlet velocity increased and in the spheric-bioreactor at the same inlet phenol concentration. The cubic-bioreactor had the highest normalized reduction rate of 1.194 at the lowest inlet phenol concentration, while the spheric-bioreactor had the lowest one of 0.871 at the highest inlet phenol concentration. The results proved the accuracy of the model to assess the performance of wastewater treatment bioreactors under different conditions.
