Mariculture yield estimation has an important significance in scientific planning and management of aquaculture scale. This study focused on the algae culture of sea area. The feasibility of constructing a remote sensing quantitative model for estimating the yield of algae culture was investigated...

Macro-algae culture has recently attracted attention in China because of its capability to sequester carbon. Here, radionuclides, total organic carbon (TOC), and nitrogen (TN) were examined in a cultivation area of macro-algae in Southeast China. At the reference site, the ratio of TOC to TN (C/N,...

To increase wastewater treatment efficiency and biofuel production, seven microalgae were mixed with activated sludge in batch bioreactors. Based on batch results, two microalgae (Chlamydomonas and Selenastrum) and their mixture were inoculated into conventional-membrane-bioreactors (CMBRs) to...

The occurrence of pesticides and their metabolites in the environment can alter the ecological relationships between aquatic food chains. Fipronil is a broad-spectrum insecticide which release in the environment may harm the non-target organisms. However, the toxicity and biotransformation of its...

Algae are low photosynthetic autotrophs, which are widely used in bio-energy and agricultural fertilizer fields, and this can greatly reduce carbon emissions in agricultural production. Therefore, the automatic cultivation and detection of algae cells in algae farms are of great significance to...

This study reports the use of Chlamydomonas reinhardtii at the cathode in a photosynthetic microbial fuel cell (PMFC). The PMFC produced power and current density of 15.21 W m^-3 and 39 A m^-3, respectively. The specific growth rate of algae culture at the cathode was 0.284 day^-1. The system achieved ...

This paper presents a new integrated process for producing carbon-negative biomethane fuel which combines anaerobic digestion of sewage sludge with biogas purification, algae generation and carbon capture. Biogas CO₂ is recovered through absorption into sodium carbonate solution, producing...

Invading microorganisms can hinder productivity of biofuel algae cultures. We utilise allelochemical gramine as a model to better understand allelopathic effects against Chlorella sorokiniana and invasive alga Coelastrella sp. Coelastrella itself inhibits C. sorokiniana via allelopathy. Both algae...

Microalgae cultivation using wastewater is a combined process for pollutant removal and lipid production that has been widely studied in recent years. In this study, the effects of anaerobic membrane effluent (AME) and municipal wastewater (MW) ratios on microalgae growth and pollutant removal...

Carbon capture and utilization (CCU) is an emerging technology with commercial potential to convert atmospheric carbon dioxide (CO₂) into net zero or negative emission products. In microalgae-based CCU, microalgae utilize CO₂ and sunlight to generate biomass for commercial applications. This paper...
