Special Issue Information

Dear Colleagues,

This Special Issue, titled “Application of Biotechnology in Water Purification”, aims to showcase and disseminate recent developments related to bio-based technologies for water treatment and pollutant removal. We aim to explore key challenges in developing sustainable bio-based processes for water and wastewater treatment.

Topics of interest for this publication include, but are not limited to, the following:

-Emerging technologies for wastewater treatment based on biological degradation;

-Use of metabolic engineering to enhance degradation of water pollutants;

-Microbial electrochemical systems;

-Integrated systems combining microbes and other advanced oxidation processes, such as photocatalysis;

-Modelling of biological systems for wastewater treatment;

-Removal of persistent pollutants, including microplastics, antibiotics, pesticides, etc.;

-Techno-economic and environmental impact assessment of hydrogen production bio-based water treatment;

-Renewable energy generation from wastewaters using microbes;

-Algal-based wastewater treatment;

-Various bioreactor configurations such as aerobic, anaerobic, membrane bioreactors, etc.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

We developed a solar-driven photo-bioelectrochemical cell (s-PBEC) employing a novel anode photocatalyst material (Co3(PO4)2/Mg(OH)2) intimately coupled with electrochemically active bacteria for synergic electricity generation from wastewater. An s-PBEC was inoculated with a natural microbial community and fed with synthetic wastewater to analyze the performance of the system for electricity generation. Linear sweep voltammetry indicated an increase in power output upon light illumination of the s-PBEC after 1 h, rising from 66.0 to 91.5 mW/m2. The current density in the illuminated s-PBEC exhibited a rapid increase, reaching 0.32 A/m2 within 1 h, which was significantly higher than the current density in dark conditions (0.15 A/m2). Shotgun metagenomic analysis revealed a significant shift in the microbial community composition with a more diverse anodic biofilm upon illumination compared to the microbial communities in dark conditions. Three unclassified genera correlated with the enhanced current generation in illuminated s-PBEC, including Neisseriales (16.31%), Betaproteobacteria (7.37%), and Alphaproteobacteria (5.77%). This study opens avenues for further exploration and optimization of the solar-driven photo-bioelectrochemical cells, paving the way for integrative approaches for sustainable energy generation and wastewater treatment.
