The biodegradable polymer poly(butylene succinate-co-adipate) modulates the community structures of actively growing bacteria in rotifer culture water.

ABSTRACT: The production efficiency of rotifers, representing a crucial feed for fish larvae, is a key factor determining fish production in aquaculture. Poly(butylene succinate-co-adipate) (PBSA) is a biodegradable polymer that enhances rotifer growth, but its effect on bacterial composition remains unknown. This study was aimed to investigate changes in the structure and function of actively growing bacterial communities in rotifer culture water after PBSA treatment. PBSA induced rapid changes in water quality, including elevated organic carbon levels, decreased pH, and increased in bacterial abundance and respiration, suggesting the elution of oligomers and monomers. Consequently, these conditions led to the increased prevalence of certain actively growing bacterial families, notably Alteromonada
