Summary: Poor nutrition and landscape changes are key factors causing the decline of wild and managed bee populations. However, the definition of 'poor nutrition' for bees is currently inadequate. Studying and characterizing the nutrient content of different pollen types is crucial for understanding pollen as a nutritional resource. Unfortunately, the use of different analytical approaches has complicated comparisons between studies and blurred our understanding of pollen nutrient content. This study proposes a unified approach for analyzing pollen nutrient content, which will help researchers better study and understand the nutritional ecology of bees and other pollen feeders.

Summary: Biodiesel, a substitute for petrochemical diesel, can be obtained from renewable raw materials. However, its production leads to a market saturation of glycerol, causing devaluation and economic unfeasibility. Despite this, research explores the use of glycerol as a raw material for biofuel production, driven by environmental concerns.

Summary: Volatile fatty acids (VFAs) produced by fermentative bacteria can be used to reduce the costs of mixotrophic microalgal cultivation. However, the assimilation of butyrate and the tolerance of microalgae to high VFA concentrations are limiting factors. In this study, Polytomella sp. was found to be the most tolerant strain and exhibited the highest growth rate on both acetate and butyrate. Additionally, Polytomella sp. and Euglena gracilis showed high carbohydrate yields, while Chlorella sorokiniana had the highest lipid yield.

Summary: Black soldier fly larvae (BSFL) is a fast-growing and promising insect species that can achieve high-fat content through organic dietary supplements and environmental conditions. The fatty acids in their body can be converted into biodiesel with high efficiency, resulting in reduced energy input and carbon emissions. This review focuses on evaluating the optimal dietary source and growth conditions to produce fatty acid-rich larvae from agro food waste, and discusses the optimization and refining of lipids using novel techniques.

Summary: Cyanobacteria-derived biofuels can be produced efficiently by mixotrophic cultivation using volatile fatty acids as a low-cost carbon source. Butyric acid was found to be more effective than acetic acid in enhancing cell growth and increasing biodiesel and bioethanol production. The study contributes to the potential commercialization of carbon-neutral fuels derived from cyanobacteria and the development of a circular bioeconomy.

Summary: The present study investigated the impact of photosynthetically active radiation (PAR), culture temperature, and urea addition on the biomass, total lipid, lipidomic profile, and fatty acid productivity in Scenedesmus obliquus (S. obliquus) and Chlorella vulgaris (C. vulgaris) for sustainable biodiesels. Results showed that both S. obliquus and C. vulgaris exhibited high cell densities and lipid contents. The optimal parameters for biomass yields were a PAR of 60 μmol/m2/sec and a temperature of 27 degrees Celsius. Urea deprivation and a PAR of 60 μmol/m2/sec resulted in the highest proportions of unsaturated fatty acids in both species.

Summary: Kitchen waste is both harmful and rich in resources, with approximately 1.3 billion tons being produced worldwide every year. Conventional treatments such as landfilling and incineration cause environmental, economic, and social problems. Therefore, there is an urgent need for harmless and resource-based treatment technology.

Summary: One of the greatest challenges of the 21st century is obtaining an ecological source of transport fuels. Biofuels based on algae offer a neutral alternative to traditional agricultural raw materials, which can lead to increased food prices and environmental degradation. This review discusses the properties and applications of algae species, the process of eutrophication and algae presence in eutrophicated reservoirs, algal cultivation technologies, biomass pretreatment methods, and the future directions of biofuel development. However, algal biofuels still face challenges in replacing fossil fuels and future work should focus on maximizing yield and quality while increasing economic viability.

Summary: Ciliophora, a phylum of common unicellular eukaryotes with pivotal roles in aquatic environments, exhibit different characteristics in sea ice and water, with sea ice having fewer taxonomic and functional richness compared to water. However, Ciliophora diversity remained stable in both sea ice and water throughout the study period, despite changes in assemblages.

Summary: In recent decades, the demand for natural and sustainable bioproducts has increased. Microalgae, with their industrial potential, have attracted much attention as promising biological resources. This study investigated the effect of light color and species-specific capability of cryptophyte algae to produce biochemical compounds. The results showed that changes in light quality significantly affect the biochemical compositions of cryptophyte algae, and species-specific responses to different light qualities were identified. The study also found that the derived biomolecules from cryptophytes had remarkable antioxidant activity, indicating that cryptophytes could be considered as potential candidates for producing beneficial biochemical compounds.

Summary: Sequencing of a mitochondrial intergenic spacer and 23S subunit was used to investigate the phylogeographic patterns in Fucus vesiculosus. A putative ancestral mitochondrial haplotype from the Atlantic entered the Baltic Sea and colonised extensively. Low overall haplotype diversity was observed, with indications of spatially aggregated patterns. No significant signals of extreme demographic changes were found. The Baltic Sea Fucus vesiculosus is confirmed as a closely related species. The relatively short temporal scale for colonisation and low variance in the mitochondrial genome results in a rather panmictic structure.

Summary: The genetic characteristics of populations have important impacts on the adaptive potential of species. This study focuses on the genetic heterogeneity in the marine macroalga Fucus vesiculosus and demonstrates marked differences in reproductive characteristics and genetic diversity between the attached and free-living forms. Asexual reproduction is common in the free-living form but almost absent in the attached form, while signals of polyploidy are observed in both forms. Gene flow between the forms is hindered due to differences in reproductive modes.

Summary: Chemotaxonomic biomarkers, such as fatty acids, sterols, and carotenoids, can be used to monitor and evaluate the nutritional quality of phytoplankton communities. These biomolecules can help classify phytoplankton groups, although some limitations exist in accurately distinguishing certain groups. The combination of fatty acids, sterols, and carotenoids yields the most accurate phylogenetic information.

Summary: Iron plays a crucial role in the physiological processes of algal growth. This study investigated the effect of different iron levels on the growth and production of bioactive compounds in five cryptophyte strains. The results showed species-specific responses to iron levels and variations in the accumulation of bioactive compounds. Additionally, each strain displayed different antioxidant activities in response to changes in iron levels.
