Summary: This study investigated the production of biodiesel from Euglena Sanguinea microalgae and custard apple using nano CaO as a heterogeneous catalyst. Different solvents were used for oil extraction, and response surface methodology was employed to determine optimal process variables. Characterization of biodiesel was done using GC-MS, and kinetic studies suggested a pseudo-first order reaction for the optimized condition of algal oil and seed oil.

Summary: A data-driven approach was used to characterize the risk of cyanobacteria-based harmful algal blooms in the Ohio River. Bayesian regression models were developed using 25 years of river discharge data to predict bloom occurrence and persistence. The models provide probabilities of occurrence or persistence with uncertainty and are served in real time through a risk characterization tool/web application. The tool also includes visualization options for studying water quality trends.

Summary: Blooms of Euglena sanguinea were observed in South Africa in 2016 and 2020, leading to blood-red water and fish mortalities. Samples from South Africa were dominated by E. sanguinea with low concentrations and diversity of other algal species. Microscopic studies confirmed the size ranges and morphology of the species as described in literature. Intensive literature searches revealed the sparse global distribution of the species with only one previous record of its presence in South Africa.

Summary: A harmful algal bloom caused by Chrysochromulina leadbeateri resulted in severe fish mortality in northern Norway in spring 2019. This study examines the succession dynamics of the marine microbiome associated with the bloom and identifies coblooming patterns of bacteria and microeukaryotes. The study reveals that the blooming patterns were distinct between different geographically separated stations and were poorly connected to environmental conditions, indicating the importance of biological interactions in shaping the dynamics of harmful algal blooms.

Summary: Phytoplankton blooms play a crucial role in marine ecosystems by providing biomass, aiding carbon sequestration, and potentially posing risks when harmful species are involved. The seasonal blooms in the Barents, Norwegian, and North seas are influenced by factors such as mixed layer depth, sea surface temperature, wind speed, and suspended particulate matter. Variability in the timing and intensity of spring and summer blooms in these regions can be attributed to unique environmental conditions and oceanographic processes.

Summary: This study investigated the molecular toxicity mechanism and regulation of humic acid (HA) on the toxicity of triclosan (TCS) and galaxolide (HHCB) in freshwater using the freshwater algae E. gracilis. The results showed that HA could alleviate the toxicity of TCS and HHCB by inhibiting TCS uptake and reducing oxidative stress, respectively. Additionally, HHCB exposure resulted in more pronounced perturbations in the purine metabolism, indicating genetic toxicity on algae. These findings provide a comprehensive understanding of the ecological risks of TCS and HHCB in natural waters.

Summary: Research shows that four harmful raphidophyte species, Chattonella malayana, C. marina, C. subsalsa, and C. tenuiplastida, coexist in tropical waters, but only C. marina is found in temperate waters. This suggests a potentially distinct ecophysiological niche and species dispersion patterns.

Summary: Sustainable aviation fuels (SAFs) can reduce greenhouse gas emissions compared to conventional fuel. The resources for SAFs have shifted from oil crops to agricultural waste and now to microalgae. Microalgae are the best feedstock for jet biofuel production due to their productivity and carbon dioxide capturing capability. However, microalgae-based biofuel faces the limitation of a high freezing point. A recently developed jet biofuel derived from Euglena wax ester has attracted attention for its low freezing point. Challenges remain in improving production yields and conducting techno-economic analysis. Valorization of industrial byproducts, such as food wastes, will ensure economic viability of biofuel production.

Summary: The Laguna Madre-Tamaulipas is the world's largest hypersaline lagoon with unique cyanobacteria and toxin production. A new filamentous cyanobacterium with drilling abilities has been discovered in this lagoon, displaying atypical behaviors. This discovery suggests the establishment of a new taxon and family due to significant morphological, physiological, and phylogenetic differences from its closest genus, Oxynema.

Summary: Euglenoids are unicellular flagellates with wide geographical and ecological distribution. They have biotechnological potential and show promise in fields such as biofuels, nutraceuticals, bioremediation, cancer treatments, and robotics design. However, the lack of reference genomes hinders the development of these applications. The Euglena International Network aims to overcome these challenges.

Summary: Phycobilins, photosynthetic pigments found in cyanobacteria, red algae, and cryptophytes, can be technically difficult to analyze due to their attachment to proteins. This study demonstrated that glycerol can uncouple PE545, a phycobilin complex, from its light-harvesting role, providing a simple method to determine its content in Rhodomonas. Additionally, recovery of PE545 from acetone-extracted cells using SDS in low pH buffers offers samples for analyzing chlorophylls and carotenoids.
