In this study, an eight-week culture trial of Penaeus vannamei juveniles was conducted in commercial intensive systems to compare the impacts biochar and molasses addition on biofloc nitrifying bacteria inorganic nitrogen dynamics under limited water exchange conditions. During trial, concentration (in terms VSS TSS), quantities total (TB) Vibrio (TV), ratio TV/TB were lower group compared group. Metagenomic sequencing analysis revealed that bacterial community composition bioflocs showed higher α-diversity complexity Moreover, abundance genera functional genes Inorganic NH4+-N NO2−-N better controlled group, as reflected by peaks NO3−-N concentrations. Excellent production performance shrimp achieved, which turn proved reliable effect mediation transformation through bacteria. These results could promote nitrification more effectively control harmful for efficient production. This study provides a practical example application biofloc-based aquaculture.

Background This study explores the impact of varying altitudes on quality characteristics Mianning ham. Methods By utilizing Solid-Phase Microextraction—Gas Chromatography–Mass Spectrometry (SPME-GC-MS) technology and high-throughput sequencing techniques, physicochemical properties, volatile flavor compounds, shifts in microbial communities ham at different were investigated. Results Ham’s water content, aw, pH, malondialdehyde content,and nitrite content high higher, while salt low was higher. 112 compounds identified fermented for 0, 1, 2 years altitude altitude, more abundant than those altitude. The main 1-octene-3-ol, Nonyl aldehyde, Octanal, 15 other compounds. At phylum level, dominant bacteria Firmicutes Proteobacteria, fungus Basidiomycota. Staphylococcus bacterium genus Aspergillus fungus.The correlation analysis microorganisms substances showed that Cobetia promoted formation Benzaldehyde altitudes. In contrast, Kocuria 1-Octanol, Heptanol,1-Butanol, 2-Heptanone, 3-Hydroxy-2-butanone, Hexanal Discussion There obvious differences between two
