About this Research Topic
Microorganisms such as microalgae, bacteria, and fungi exhibit characteristics of small size, rapid growth/reproduction rates, and strong adaptability. They hold immense potential in the utilization of by-products from agricultural and food processing, also the harmless treatment and resource utilization of waste materials like biogas slurry and brewery wastewater. Additionally, they offer possibilities for producing high-value-added compounds and products such as lipids, proteins, polysaccharides, and prebiotics during waste recycling. However, challenges persist in achieving efficient cultivation, cost-effective biomass harvesting, and the low-cost extraction of high-value-added compounds. Moreover, there is a need for in-depth research into the metabolic regulation mechanisms of microorganisms concerning different treatment substrates and the targeted synthesis of diverse high-value-added compounds. Specifically, understanding the synergistic interactions among multiple microorganisms for enhanced substance utilization and the precise mechanisms underlying the production of high-value-added compounds requires further investigation.
Expanding the applications of microalgae, bacteria, fungi, and their symbiotic organisms in by-products and waste harmless treatment, and high-value-added compound production requires the development of novel, efficient bioreactors, strains tailored to specific demands, and innovative, cost-effective methods for biomass harvesting and high-value compound extraction. Meanwhile, microalgal-microbiome symbiosis (Microalgal-bacterial biofilms, microalgal-bacterial granular sludge, etc.) can be self-sustaining systems that offer an energy-efficient and manageable option for low-cost wastewater treatment with enhanced efficiency of degradation of organic pollutants and removal of inorganic pollutants compared with the actions of either of the partners alone. Indeed, it's also essential to enrich and advance research into the microbial metabolic regulation mechanisms involved in relevant processes, particularly the molecular biological mechanisms behind the synergistic interactions (nutritional reciprocity, signal transduction, toxic resistance, transcriptional responses, horizontal gene transfer, etc.) among multiple microorganisms that drive waste recycling, and the synthesis of high-value-added compounds.
This Research Topic welcomes contributions focusing on the application and fundamental research of microbes for utilizing low-quality agricultural waste materials, and the production of high-value-added compounds. Submissions may include studies on the development of efficient bioreactors, low-cost biomass harvesting, and the design of extraction processes for high-value compounds. Additionally, research on microbial metabolic regulation mechanisms during these processes is encouraged, particularly exploring the molecular biological mechanisms underlying the synergistic interactions among multiple microorganisms that drive harmless treatment of by-products and waste, resource utilization, and the synthesis of high-value-added compounds.
