Cultivation of microalgae–bacteria consortium by waste gas–waste water to achieve CO2 fixation, wastewater purification and bioproducts production

Biotechnology for Biofuels and Bioproducts, Journal Year: 2024, Volume and Issue: 17(1)

Published: Feb. 15, 2024

Abstract The cultivation of microalgae and microalgae–bacteria consortia provide a potential efficient strategy to fix CO 2 from waste gas, treat wastewater produce value-added products subsequently. This paper reviews recent developments in fixation treatment by single microalgae, mixed consortia, as well compares summarizes the differences utilizing different microorganisms aspects. Compared monoculture consortium may mitigate environmental risk, obtain high biomass, improve efficiency nutrient removal. applied include Chlorella sp., Scenedesmus Pediastrum Phormidium sp. among others, most strains belong Chlorophyta Cyanophyta. bacteria are mainly activated sludge specific sewage sources. Bioengineer CBB cycle cells effective achieve improvement or yield high-value products. mechanisms removal microbial systems also explored concluded, importance technology is proven. After cultivation, biomass can be harvested through physical, chemical, biological magnetic separation methods used by-products, such biofuel, feed, food, biochar, fertilizer, pharmaceutical bio-compounds. Although this has brought many benefits, some challenging obstacles limitation remain for industrialization commercializing. Graphical

Effect of konjac glucomannan aerogel‐immobilized Chlorella vulgaris LH‐1 on oil‐contaminated seawater remediation and endogenous bacterial community diversity

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(1)

Published: Jan. 1, 2025

Abstract Ocean oil spills can severely impact ecosystems and disrupt marine biodiversity habitats. Microbial remediation is an effective method for removing thin slick contamination. In this study, the adsorption degradation of low‐concentration by Chlorella vulgaris LH‐1 immobilized in konjac glucomannan (KGM) aerogel were investigated. The effect KGM aerogel‐immobilized C. on bacterial community structure seawater environments was analyzed through diversity sequencing. containing 0.01 1.00 g/L crude oil, after 14 days with , removal rates 98.73% 95.13% achieved, respectively. FDA hydrolytic enzyme activity curve indicated that microbial growth group significantly higher than other groups. After remediation, top three dominant genera found to be Vitellibacter Roseitalea Methylophaga . a genus known its ability degrade polycyclic aromatic hydrocarbons (PAHs) environments, showed increased abundance treated suggesting enhanced PAH capability presence Functional prediction using PICRUSt metabolism bacteria promoted Practitioner Points High efficiency across various concentrations exhibited KGM‐immobilized microalgae. aerogels effectively confine C.vulgaris reducing loss systems. analyzed.

Effects of Different pH Control Strategies on Microalgae Cultivation and Nutrient Removal from Anaerobic Digestion Effluent

Microorganisms, Journal Year: 2022, Volume and Issue: 10(2), P. 357 - 357

Published: Feb. 3, 2022

This study investigated nutrient removal from anaerobic digestion effluent by cultivating mixed-culture microalgae enriched sludge under different pH conditions: RUC (uncontrolled), R7-8 (maintained at 7-8), and R<8 below 8). Significant amounts of NH4+-N were lost volatilization in cultures due to increased values (≤8.6) during the early period cultivation. The control strategies significantly affected biological (highest R7-8), microalgal growth biomass settleability R<8), relative bacteria R<8) cultures. Parachlorella completely dominated communities inoculum all cultures, grew well highly acidic (<3) induced culture acidification with growth. Microalgae-associated bacterial community structure developed very differently among findings call for more attention influence changes cultivation treatment effluent.
