Metatranscriptomic Analysis of Interaction Mechanisms Between Heterotrophic and Autotrophic Denitrifiers in Mixotrophic Denitrification Systems
This study aims to investigate the interaction mechanisms between dominant heterotrophic denitrifiers and sulfur-autotrophic denitrifiers in a mixotrophic denitrification sludge system, using metatranscriptomic analysis. We will analyze the gene expression profiles related to denitrification and sulfur metabolism, reveal the symbiotic and metabolic complementation patterns within the microbial community, and provide insights into the functional stability and efficiency of mixotrophic denitrification processes.
