Contact Dr Mithil Mahale

Background

Dr Mithil Mahale is a Research Fellow in Phototrophic Bioprocesses at the Cranfield Water Science Institute, Cranfield University, with expertise in environmental microbiology, microbial bioremediation, water quality monitoring, and biological wastewater treatment. His research focuses on harnessing microorganisms and phototrophic bioprocesses to address environmental challenges, including microbial remediation of hazardous pollutants, bacteriophage ecology and monitoring in water systems, and resource recovery from wastewater and waste-derived streams.

His current research focuses on the development and optimisation of purple non-sulphur bacteria (PNSB)-based phototrophic bioprocesses for the treatment of liquid digestate and biorefinery effluents. This work investigates nutrient removal, biomass production and recovery of value-added products such as polyhydroxyalkanoates (PHAs), contributing to the development of resource-efficient and circular approaches to wastewater and waste management.

His doctoral research at Savitribai Phule Pune University, awarded in January 2026, investigated microbial remediation of the "Toxic Trio", heavy metals, antibiotics, and other hazardous contaminants from wastewater under a One Health framework. This work elucidated the genomic and mechanistic basis of pollutant remediation by environmental bacteria, exemplified by the characterisation of Achromobacter sp. M1, published in the Journal of Hazardous Materials (2024).

Mithil brings broad technical expertise spanning environmental microbiology, microbial cultivation, molecular biology, enzymology, and analytical chemistry. His technical experience includes PCR, RT-qPCR, Sanger and Nanopore sequencing, NGS bioinformatics, HPLC, FTIR, microbial cultivation and characterisation, and wastewater analysis.

Current activities

Dr. Mithil Mahale is currently working on the development of phototrophic bioprocesses using purple non-sulphur bacteria (PNSB) for the treatment of liquid digestate and biorefinery effluents within the European OLinWASTE project. His work focuses on optimising PNSB cultivation under different operating conditions, including near-infrared light intensity, digestate dilution and microbial source, with the aim of improving nutrient removal and biomass production.

A key focus of his research is the recovery of value from waste-derived streams through PNSB-based bioprocesses, including the production and accumulation of polyhydroxyalkanoates (PHAs). The work contributes to the development of scalable and resource-efficient processes for nitrogen and phosphorus removal, biomass recovery and bioproduct generation within a circular bioeconomy framework.

His previous research at Cranfield also included the investigation of microplastic generation within wastewater treatment works through attrition, supporting the validation of pilot-scale treatment systems and the development of approaches for improved microplastic removal.

He has also investigated the role of somatic coliphages as viral indicators for water treatment strategies, contributing to the development of microbial monitoring frameworks for drinking water safety. This work, funded by UK Water Industry Research (UKWIR), integrates culture-based phage methods with sequencing-enabled approaches to improve understanding of microbial risk and treatment efficacy.
