Investigation on the feasibility of Chlorella vulgaris cultivation in a mixture of pulp and aquaculture effluents: treatment of wastewater and lipid extraction
Open accessAbstract
In this study, feasibility of Chlorella vulgaris cultivation in pulp wastewater (PWW) diluted with lake water (LW) and aquaculture wastewater (AWW) was investigated. The best ratios of PWW and AWW (PAWW) viz., 80% PWW:20% AWW and 60% PWW:40% AWW were selected as microalgal culture medium. Algal growth was investigated with and without addition of macro and micronutrients to the cultivation medium. The highest dry algal weight was observed as 1.31 g/L in 60% PWW:40% AWW without adding micronutrients. Nutrients and organic compounds removal efficiencies by microalga were studied in PAWW. Protein, carbohydrate and lipid percentage of harvested microalga from wastewater and Bold's Basal Medium (BBM) solution were analyzed. Fatty acids analysis revealed that C16 and C18 are the major fatty acids in C. vulgaris cultivated in BBM and PAWW. The results of this study revealed that C. vulgaris is a potential candidate for PAWW treatment and lipid and carbohydrate accumulation.

Microalgae-mediated pharmaceutical bioremediation has benefits including being solar-powered, having low operational costs, being environmentally friendly, and contributing to carbon fixation and turnover.

From Microalgae-based wastewater treatment: Mechanisms, challenges, recent advances, and future prospects (2023) · cites this paper as [152]
The Introduction (page not provided) describes microalgal wastewater treatment as inexpensive and eco-friendly, says most microalgae grow using sunlight and CO₂, and notes that treatment avoids expensive chemicals. Section 3.3 (page not provided) reports that C. vulgaris uses organic carbon in wastewater. The paper does not establish these benefits specifically for pharmaceutical bioremediation; it mentions antibiotics as possible wastewater contaminants but does not report their removal.

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.
