A Novel Miniature Culture System to Screen CO2-Sequestering Microalgae

open access: yesEnergies, 2012
In this study, a novel 96-well microplate swivel system (M96SS) was built for high-throughput screening of microalgal strains for CO2 fixation. Cell growth under different CO2 supply conditions (0.2, 0.4, 0.8, and 1.2 g L−1 d−1), residual nitrate, and pH

Selenastrum Capricornutum: Harvesting and Oil Extraction, for Biodiesel Production

open access: yesEuropean Journal of Sustainable Development, 2015
An alternative for biodiesel production is the use of lipids from microalgae. Although all steps to obtain this biofuel are important, harvesting and extraction are the most important. Advances in these areas are necessary in order to obtain third-generation fuels.

Seasonal Variation of Enzymatically Hydrolyzable Organic Phosphorus in Agricultural Drainage Waters

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 7, July 2025.
Abstract Phosphorus (P) export studies in agricultural watersheds have generally focused on soluble reactive P (SRP), the P fraction generally considered as readily available for biological uptake. However, in some settings, the amount of dissolved organic P (DOP) in agricultural drainage waters can be significant and may represent another important ...

Application of algal bioassays in the determination of eutrophic power of waste water (”Conclusions” only) [Translation from: 1g.Sanita pubbl. 31 257-267, 1975] [PDF]

open access: yes, 1977
The best evidence for establishing the level of eutrophy of a water-body is its algal production which makes it possible to identify the type and the intensity of the eutrophication according to the kind and number of algal species present: when the ...

Anthracene phytotoxicity in the freshwater flagellate alga Euglena agilis Carter [PDF]

open access: yes, 2019
The freshwater flagellate alga Euglena agilis Carter was exposed to the polycyclic aromatic hydrocarbon (PAH) anthracene for 96 h under optimal photosynthetically active radiation (PAR), and responses of growth, photosynthetic pigment production, and ...

Toxicity of the sunscreen UV filter benzophenone-3 (OBZ) to the microalga Selenastrum capricornutum: An insight into OBZ’s damage to photosynthesis and respiration

open access: yesEcotoxicology and Environmental Safety
Oxybenzone (OBZ; benzophenone-3, CAS# 131–57–7), as a new pollutant and ultraviolet absorbent, shows a significant threat to the survival of phytoplankton.

Anthropogenic impacts on the contamination of pharmaceuticals and personal care products (PPCPs) in the coastal environments of the Yellow and Bohai seas

open access: yesEnvironment International, 2020
Pharmaceuticals and personal care products (PPCPs) are recognized as one emerging group of environmental contaminants, capturing worldwide attention. These chemicals, closely connected to anthropogenic activities, are mainly transported through aquatic ...

The microbiotest battery as an important component in the assessment of snowmelt toxicity in urban watercourses—preliminary studies [PDF]

open access: yes, 2015
The aim of the study was to use a battery of biotests composed of producers (Selenastrum capricornutum, Sorghum saccharatum, Lepidium sativum, and Sinapis alba), consumers (Thamnocephalus platyurus), and decomposers (Tetrahymena thermophila) to ...

Exposure, body size, and zooplankton overland dispersal capacity

open access: yesLimnology and Oceanography, Volume 70, Issue 1, Page 15-24, January 2025.
Abstract The dormant life stages of freshwater zooplankton are generally resistant to environmental exposure, and this facilitates their overland dispersal. However, environmental exposure and overland dispersal are less well studied for the active life stages of freshwater zooplankton.
