About this Research Topic
Since the dawn of the industrial revolution, the chemical industries have played a pivotal role in modernizing and transforming our daily life by providing various consumer goods and services. These industries are, therefore, considered as the backbone of modern economies and industrialized nations around the world. Ironically, these industries are the primary contributors to the current climate crisis caused by the unprecedented rise in global greenhouse gas (GHG) emissions. Thus, sustainable chemical industries incorporating innovative biological, electrochemical, and biochemical processes to recycle and reuse GHGs to curb their emissions can not only help tackle the climate emergency but also help achieve and secure a sustainable net-zero future.
Sustainable chemical industries can be developed through implementing state-of-the-art, innovative, and sustainable chemical and biochemical processes, including single carbon-gas fermentation, mixotrophic fermentation, microbial electrosynthesis, and electro-fermentation. Although these innovative and promising alternatives have shown encouraging results in lab-scale experiments, further upstream and downstream optimization of these processes are required before considering them for industrial-scale applications. Such upstream and downstream optimization possibilities involve the development of appropriate cell factories/chassis strains, required biochemical pathways and their engineering into cell factories/chassis strains, appropriate logistics and support systems including electrochemical cells and bioreactors suitable for microbial electrosynthesis and electro-fermentation applications. The goal of this Research Topic is to highlight and promote these technologies.
