文摘

An autochthonous microalgal-bacterial consortium was cultivated mixotrophically. The link between reactor performance and microbial community changes was identified. Stepwise increase in VFAs concentration enhanced algal biomass and lipid production. VFAs produced from sewage sludge were efficiently used as organic carbon sources. The addition of VFAs benefited enhanced nitrogen and phosphate removals.
