Effects of Intracellular and Extracellular Substances of Chlorella Pyrenoidosa on Water Quality, Floc Formation, and Microbial Composition in Biofloc System

Published: Jan. 1, 2025

Chlorella pyrenoidosa was recognized for its ability to bolster biofloc formation, but the specific components responsible this enhancement have not been fully elucidated. In study, six groups were set up—algal cell culture solution (ACC), algal cells (AC), extracellular secretions (ES), intracellular substances (IS), fragments (CF), and medium (CK)—to assess their impacts on water quality, microbial community structure. The results revealed that IS group of had highest flocculation rate, total amount flocs in each ranked as > AC CF ACC CK ES. significantly outperformed other promoting having largest 400 mL/L. component could provide essential nutrients growth enhance floc stability by increasing prevalence dominant bacterial genera such Flavobacterium Shinella. addition contributed removal nitrogen. achieved a nitrogen rate up 40%, while ES demonstrated efficiency, reaching 80%. These findings are pivotal elucidating role formation quality regulation.
