Enhanced biomass production and bioelectricity generation in microalgae culture medium using electrode pairings

E3S Web of Conferences, Journal Year: 2025, Volume and Issue: 603, P. 03007 - 03007

Published: Jan. 1, 2025

Microalgae-based biofuel production offers promising avenues for sustainable energy generation. However, optimizing microalgae culture conditions enhanced biomass and bioelectricity generation remains challenging. This study addresses this problem by investigating the efficacy of different electrode pairings immersed in a medium. Two pairs, Al-Fe Cu-Zn were evaluated their impact on growth production. The optimum concentration obtained was 1.204 g/L electrodes with lipid content 15.1% 0.36V. results demonstrated that induced high culture, facilitating biodiesel Conversely, Cu paired Zn promoted elevated 0.95V. research sheds light potential tailored to optimize dual-purpose biofuels production, contributing advancement technologies. It recommended, among others, further exploration diverse within cultured medium could unveil additional effective strategies

An Investigation of the Impact of Flocculants on Process Optimization and Floc Properties in Chlorella vulgaris FACHB-15 Harvesting

Water, Journal Year: 2025, Volume and Issue: 17(7), P. 932 - 932

Published: March 22, 2025

This study systematically compared the harvesting efficiency and flocculation mechanisms of a bioflocculant (chitosan) chemical flocculant (Al2(SO4)3) for Chlorella cells. For first time, divergent underlying floc structure formation between two flocculants were elucidated by analyzing EPS distribution dynamic changes in microalgal surface functional groups. By optimizing critical operational parameters—including dosage, pH, biomass concentration—the optimal dosages chitosan Al2(SO4)3 determined as 0.5 mg/L 90 mg/L, respectively. Under pH 6, both achieved over 99% within 30 min. Notably, at dosage 3 chitosan-formed flocs exhibited denser structures, stronger adhesion, tendency to aggregate into spherical clusters Al2(SO4)3-induced flocs. Beyond identifying ideal conditions flocculation, this work provides novel insights role groups mechanisms, offering theoretical foundations practical guidance efficient harvesting. The findings hold significant implications applications advancing environmentally sustainable technologies.

Effects of Light Quality Adjustment in Microalgal Cultivation: Flashing Light and Wavelength Shifts in Photobioreactor Design

Processes, Journal Year: 2025, Volume and Issue: 13(4), P. 1159 - 1159

Published: April 11, 2025

The distribution of light within a microalgal culture and the choice best wavelengths are considered most critical aspects in scale-up culture. Several studies have investigated these features, resulting substantial body literature that analyzes effects terms an increase biomass production or shift its composition. This work addresses two types quality adjustments: application flashing shifts wavelength. on examined. Later, features to photobioreactor design is described. Specifically, three kinds photobioreactors examined: (1) reactors designed minimize gradients, (2) where geometry produces effect cells (3) use filters obtain sunlight results showed both lights wavelength strongly depends various parameters such as alga taken into consideration, intensity, agitation type, growth medium, intensity temperature and, regarding also, frequency duty cycle. Despite all specific differences, this aims resume provide instruments for choosing operational cultivation achieve targeted outcomes, high-value compound accumulation.
