Abstract

The use of microalgae for wastewater treatment has been proposed as a cost-effective method to produce biofuels while remediating waste streams. This study examined the microalgae biomass production rate, wastewater treatment efficiency, and prokaryotic organism microbiome associated with microalgae Chlorella sorokiniana cultivated on anaerobic digestate effluent. Final microalgae biomass concentrations from nine photobioreactors were highly variable and had values that ranged between 0.14 g/L and 0.90 g/L. Nutrient removal efficiencies for TN (total nitrogen), N-NH 4 (ammonium nitrogen), and COD (chemical oxygen demand) ranged from 34% to 67%, 65% to 97%, and-60% to 14%, respectively. Analysis of individual OTUs (operational taxonomic units) from the microbial community revealed that microalgae biomass concentrations were significantly correlated with the relative abundance of OTUs in the genus Pusillimonas. Predictive metagenomic analyses identified additional correlations associated with biomass production and nutrient removal. These results suggest that the microbial community present during microalgae cultivation on wastewater can impact the performance of the system for biomass production and wastewater treatment.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Analyses of the microbiome associated with Chlorella sorokiniana cultivated on anaerobic digestate effluent revealed that the microalgae biomass was correlated negatively with the relative abundance of the genus Pusillimonas.

    “For instance, analyses of the microbiome associated with the microalga Chlorella sorokiniana cultivated on anaerobic digestate effluent revealed that the microalgae biomass was correlated negatively with the relative abundance of the genus Pusillimonas [98].”
  • The use of microalgae-bacteria consortia in wastewater treatment has been widely studied, revealing that the microbial community plays an important role on the performance of the system.

    “Therefore, the use of microalgae–bacteria consortia in wastewater treatment has been widely studied, revealing that the microbial community plays an important role on the performance of the system [98,99,100].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
