Summary: The research on sustainable alternatives for producing valuable polyunsaturated fatty acids (PUFAs) has been promoted due to the limited supply of wild deep-sea fish and the potential accumulation of toxic pollutants. In this study, an evolved strain of Phaeodactylum tricornutum microalgae was generated through adaptive evolution, resulting in enhanced biomass and PUFA production capabilities. The use of food waste hydrolysate as a carbon source further improved biomass yield and PUFA production. This study provides novel insights into sustainable microalgal-based waste valorisation for PUFA production.

Summary: The transcription factor NRF2 and its endogenous inhibitor KEAP1 are important for maintaining cellular redox homeostasis. Activation of NRF2 can provide cellular protection against age-related diseases. Recent studies have identified compounds, including omega-3 polyunsaturated fatty acids (PUFAs) and their electrophilic derivatives, that may restore NRF2 function in aging cells. These findings suggest that n-3 PUFAs could be potential agents for preventing chronic diseases and restoring age-related NRF2 impairment.

Summary: This study reveals that Fas-associated factor 1 (FAF1) interacts directly with free polyunsaturated fatty acids (PUFAs) and this interaction is crucial for protecting cells from ferroptosis. FAF1 assembles a globular structure that sequesters free PUFAs into a hydrophobic core, preventing PUFA peroxidation and ultimately inhibiting ferroptosis initiation.

Summary: The study investigated the relationship between red blood cell fatty acid status and lymphocyte telomere length (LTL) in 174 healthy older South Australians. Results showed that saturated and monounsaturated fatty acids were negatively associated with LTL, while polyunsaturated fatty acids, particularly arachidonic acid (C20:4n-6), were positively correlated with LTL. Further research is warranted into the significant association of fatty acids, especially C20:4n-6, with telomere length.

Summary: In this study, it was discovered that treatment of Haematococcus pluvialis cultures with rac-GR24 resulted in increased biomass and astaxanthin production. This enhancement was achieved by improving CO2 utilization efficiency, stimulating the production of NADPH and antioxidant enzymes, and altering the activity of fatty acid biosynthesis and astaxanthin esterification pathways. The findings provide new insights into the mechanistic roles of rac-GR24 and offer a feasible and economic strategy for increasing the amounts of biomass and astaxanthin generated by H. pluvialis cultures.

Summary: Microalgae are being investigated as green cell factories for biochemistry and pollution control. This study focuses on enhancing the synthesis of selenium nanoparticles (SeNPs) in microalgae and understanding the molecular mechanisms involved. Chlorella vulgaris was fortified with quercetin to promote SeNPs biotransformation. Quercetin facilitated the formation of SeNPs within 72 hours, converting almost 97% of inorganic selenite to SeNPs. Electron microscopy confirmed the biogenic ability of the algal system. Quercetin fortification protected C. vulgaris from selenite-induced impairment and improved its growth rate, while also altering the fatty acid profile.

Summary: In this study, the genetic structure and diversity of Colletotrichum gloeosporioides, the dominant species causing citrus anthracnose, were analyzed using the Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene. A total of 19 GAPDH haplotypes were identified, with the main haplotype (haplotype 5) distributed widely among isolates from different Citrus species and locations. The genetic differentiation index (Fst) revealed significant genetic differentiation between populations from different regions and host species. The results suggest that genetic differentiation in C. gloeosporioides is mainly influenced by gene mutation, recombination, or migration within native populations rather than natural selection caused by geography or host variety.

Summary: Microalgae-based antibiotic removal treatment has gained attention due to its low carbon and sustainable advantages. By using a suitable carbon source, microalgae can enhance the removal of pollutants through co-metabolism. However, there is limited knowledge about the removal of fluoroquinolone using a microalgae-mediated co-metabolism system. This study investigated the biotic processes of Haematococcus lacustris in a co-metabolism system with glycerol, which achieved significant removal efficiencies of 79.73% for ofloxacin (OFL) and 54.10% for enrofloxacin (ENR), respectively. The study also identified the metabolites and pathways involved in the biodegradation of fluoroquinolone by H. lacustris, and demonstrated the involvement of cytochrome P450 (CYP450) enzymes in this process. Molecular dynamic simulation further confirmed the binding conformation of fluoroquinolones with CYP450. These findings provide a microalgae-based approach for sustainable biodegradation of antibiotics using a co-metabolism strategy with glycerol, leading to the accumulation of valuable products.

Summary: The excessive accumulation of catechol in the environment due to its burgeoning commercial applications poses a severe ecological threat. This study investigated the potential of the microalga Crypthecodinium cohnii to degrade catechol and utilize the byproduct as a carbon source. Results showed that catechol significantly increased the growth of C. cohnii and was rapidly catabolized within 60 hours. Transcriptomic analysis identified key genes involved in catechol degradation, and real-time polymerase chain reaction (RT-PCR) analysis revealed a remarkable increase in the transcription of these genes. The study also demonstrated altered primary metabolite content and the ability of C. cohnii to tolerate catechol treatment without adverse effects.

Summary: This study conducted Life Cycle Assessments (LCA) to evaluate the environmental impact of laboratory-scale EPA production by Phaeodactylum tricornutum. The results showed that technical advancements, particularly metabolic engineering, significantly reduced the global warming potential and cumulative energy demand associated with EPA production. Electricity consumption and extraction solvents were identified as the main contributors to the environmental impact. The study suggests future directions should focus on increasing EPA productivity, adopting alternative cultivation approaches with less energy input, and implementing environmentally friendly methods for EPA recovery.

Summary: Studies have found that there are reciprocal inhibitory effects between Karenia mikimotoi and Prorocentrum shikokuense under co-cultures. RNA sequencing analysis revealed that genes involved in photosynthesis, carbon fixation, energy metabolism, nutrients absorption and assimilation were up-regulated in K. mikimotoi after co-cultured with P. shikokuense, while genes involved in DNA replication and cell cycle were down-regulated. In contrast, genes involved in energy metabolism, cell cycle, and nutrients uptake and assimilation were down-regulated in P. shikokuense under co-culture with K. mikimotoi. Additionally, the expression of PLA2G12 and nitrate reductase, which may play important roles in the allelopathy of K. mikimotoi, was significantly increased. These findings provide new insights into the interspecies competition between K. mikimotoi and P. shikokuense and offer a novel strategy for studying interspecific competition in complex systems.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
