The tiger shrimp Penaeus monodon is a commercially important species; however, the intensification of farming this species has led to production and release significant amounts organic waste. Traditional aquaculture uses water exchange for waste removal, which may cause pollution infection reared with external pathogens. This study aimed evaluate effects two different modes on antioxidant status, nonspecific immune response, growth performance P. monodon, reveal differences in their microbial communities. experiment was divided into groups: one using bioflocs zero (Group ZC), other clear system C). results showed that, compared those Group C, ZC exhibited higher final body weight, lower feed conversion ratio, survival rate, unit yield. Additionally, digestive enzyme activities, as well upregulated expression immune-related genes (such lysozyme, anti-lipopolysaccharide factor, Toll-like receptors). Therefore, biofloc technology can improve performance, immunity, capacity offering an environmentally friendly efficient model farming.

Substrate utilization and secondary metabolite biosynthesis in the phylum Planctomycetota

Applied Microbiology and Biotechnology, Journal Year: 2025, Volume and Issue: 109(1)

Published: May 15, 2025

Abstract The phylum Planctomycetota is changing our understanding of bacterial metabolism, driving critical biogeochemical processes through the transformation complex polymeric substrates into valuable bioactive compounds. Sophisticated methods for cultivation, genome sequencing and genetic strain engineering developed in last two decades have stimulated detailed studies on cell propagation, metabolic capabilities potential applications members beyond mere isolation characterization novel taxa. This review synthesizes recent advances physiology with a focus degradation phototroph-derived polysaccharides, anaerobic ammonium oxidation (anammox) biosynthesis secondary metabolites. New data especially collected over 5 years justifies more intensive research yet uncharacterized pathways substrate uptake utilization, as well mining-assisted bioprospection to exploit phylum's chemical repertoire. Key points • Planctomycetes can degrade high-molecular-weight sugars produced by algae Anaerobic used technical first metabolites were discovered
