SynCom + Chlorella sorokiniana Biogas-slurry Coupling System

Community ID CommunityMech:000285
Ecological State ENGINEERED
Environment livestock biogas slurry treatment bioreactor
ENVO:00002123

A sequential synthetic microbial community (SynCom)-microalga coupling system engineered to treat livestock biogas slurry. An autochthonous microalga, Chlorella sorokiniana, isolated from the slurry is coupled with a SynCom pretreatment stage. The system operated stably for 60 days, achieving 94.41% nitrate-nitrogen removal, 81.84% total-phosphorus removal, and 6.31% chemical oxygen demand removal. SynCom pretreatment increased the biomass and soluble protein content of C. sorokiniana (by 27.15% and 488.10% vs the BG11 control), upregulating Rubisco and glutamine synthetase, providing a strategy for simultaneous pollutant abatement and resource recovery.

COMMENSALISM

Target Taxon: Chlorella sorokiniana

Evidence

    "SynCom pretreatment increased the biomass and soluble protein content of C. sorokiniana by 27.15% and 488.10%, respectively"

Growth Media

livestock biogas slurry (SynCom-pretreated); BG11 (control)

Preparation notes: Chlorella sorokiniana grown on SynCom-pretreated livestock biogas slurry in a sequential SynCom-microalgae coupling system operated stably for 60 days; BG11 medium served as the growth control. Reported slurry effluent typically had total nitrogen 56.5-830 mg/L and total phosphorus 0.2-476 mg/L. System temperature, pH and light regime not stated in the accessible abstract.
