Earth and Environmental Sciences: Microalgal-bacterial Processes

With fast-evolving global climate change, increasing efforts have been dedicated to the mitigation of greenhouse gases emission from municipal wastewater treatment plants. Considering that carbon taxing and trading schemes have been gradually implemented worldwide, an increase in future operating costs of wastewater treatment would be inevitable. As such, great attention has been paid to carbon-neutral or even carbon-negative municipal wastewater treatment technologies. Since microalgae can grow upon inorganic carbon from the bio-oxidation of organics by bacteria, microalgae-bacteria consortia are believed to serve as a carbon sink for wastewater treatment. Moreover, the circular economy is game-changing wastewater management with the aim to maximize water reuse, energy and resource recovery from wastewater. Given such a situation, this Topical Collection will focus on microalgae-bacteria-based technologies for carbon-neutral wastewater treatment, meanwhile highlighting the latest technology advancements. We welcome high-quality research articles and state-of-the-art critical reviews including, but not limited to, the following areas: (1) Emerging microalgae-bacteria-based technology; (2) Microbial structures and metabolisms of microalgae-bacteria; (3) Microalgal-bacterial granular sludge; Algal-bacteria granular sludge; Photogranule; (4) Circular economy-driven microalgae-bacteria-based technologies towards carbon neutrality of wastewater treatment; (5) Recovery of value-added products from microalgal-bacterial biomasses.
