Sulfur (S) is an essential nutrient for plant growth, influencing not only crop yields but also the composition and function of soil microbial communities. However, differential effects S fertilization on abundant rare taxa in agricultural soils remain poorly understood. This study investigates impact different fertilizer types maize yield structure stability communities, with a particular focus taxa. led to significant increases two typical (black sandy soil) (5.3–24.3%) altered properties, including reducing pH (0.04–0.20) increasing available sulfur (AS) content (3.8–8.0 mg kg−1), ammonium sulfate having more pronounced effect than elemental sulfur. Microbial analysis revealed distinct impacts diversity community both Elemental reduced alpha sulfate, while NMDS indicated shifts structures, particularly among Network showed that decreased complexity interactions taxa, leading simpler networks resulting higher modularity. SEM highlighted played crucial role yield, alongside direct from properties such as AS SAR (aryl sulfatase). Functional predictions demonstrated amino acid metabolism xenobiotic biodegradation pathways were enriched suggesting implications health productivity. provides new insights into roles bacterial under fertilization, emphasizing their importance optimizing strategies enhanced specific types.

Abstract Algae-bacteria interactions play an essential role in the transformation of complex organics microalgal-bacterial granular sludge (MBGS), but intrinsic removal mechanisms have not been well understood. This study thus attempted to investigate performance and real municipal wastewater MBGS process. The results showed that could be effectively disposed during day-night cycles by MBGS, with process significant impacted influent C/N ratio. Further metagenomic metatranscriptomic analyses revealed upregulated gap2 gpmA genes glycolysis enhanced conversion CO2 mediated Chlorophyceae Acidobacteriae/Sumerlaeia/Fimbriimonadia, while petH gene NADPH synthesis Cyanobacteria strengthened fixation into biomass. Meanwhile, functional amyA starch metabolism Actinobacteriota was upregulated, along gldA glycerolipid through Chloroflexia/Verrucomicrobiae. Moreover, a close symbiotic relationship between Desulfobacterota I identified, which played crucial fatty acid decomposition. offers new insights degradation via symbiosis, also gains basic knowledge on carbon cycle natural water ecosystems symbiosis.
