Summary: Microalgae, which play critical roles in the food web and biogeochemical cycling, are commercially exploited for the compounds they produce. This study investigated the effects of microplastic contamination on Spirulina, a widely distributed and commercially important cyanobacterium. The results showed that increasing concentrations of microplastics led to a decrease in growth rate and photosynthetic activity, as well as oxidative stress and production of proline. Microplastics were observed to adhere or aggregate around fragmented regions, potentially providing a mechanism for internalization.

Summary: In this study, an environmentally friendly sensor was used to measure the anticholinergic drug Atropine. Self-cultivated Spirulina platensis with electroless silver and 1-Hexyl-3 methylimidazolium Hexafluorophosphate (HMIM PF6) ion liquid were employed as materials for electrode modification. Voltammetry methods were used to determine Atropine, and pH 10.0 was found to be the optimal condition. The fabricated sensor showed linear responses in the concentration range from 0.01 to 800 μM, with a lowest detection limit of 5 nM. The stability, reproducibility, and selectivity of the sensor were confirmed, and it was successfully applied to the determination of Atropine in real samples.

Summary: This study used pancreatin and pepsin to extract bioactive peptides from Spirulina platensis protein and evaluated their techno-functional and antioxidant characteristics. The results showed that pepsin hydrolysates had higher hydrolysis and antioxidant activity compared to pancreatin hydrolysates. The hydrolysates also reduced lipid oxidation in emulsions. The digested peptides retained their antioxidant activity. H-Pep from Spirulina algae could be a promising protein source for food products with good nutritional value.

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.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
