Summary: The coal-to-gas process produces carbon dioxide, leading to global warming, and its wastewater treatment results in highly organically toxic sludge. Scenedesmus obliquus is a promising solution to these environmental issues, with a focus on its photosynthetic pigments. The optimal CO2 concentration for the growth of Scenedesmus obliquus was found to be 30% after increasing the CO2 concentration from 0.05% to 100%. The cultivation of Scenedesmus obliquus resulted in the accumulation of photosynthetic pigments and a significant reduction in the organic toxicity of the sludge extract.

Summary: Tetracycline antibiotics can have toxic effects on freshwater microalgae, but at lower concentrations, the microalgae are able to recover and show enhanced photosynthetic activities. The transcriptomic analysis revealed differentially expressed genes related to photosynthesis. This study provides insights into the environmental risk of Tetracycline antibiotics and their effects on photosynthesis.

Summary: In this study, the impact of AgNPs stabilized with different coatings on photosynthesis of tobacco plants and AgNP stability in exposure medium was investigated. Results showed that AgNP-citrate induced the least effects on chlorophyll a fluorescence parameters and pigment content due to fast agglomeration, while AgNP-PVP and AgNP-CTAB had more severe effects related to their stability, Ag accumulation, and surface charge. In conclusion, the intrinsic properties of AgNP coatings affect their stability and bioavailability, indirectly impacting photosynthetic apparatus.

Summary: The main goal of this study is to find scalable ways to produce a highly concentrated biomass of Scenedesmus rubescens in heterotrophic conditions. By optimizing the medium through response surface methodology, the growth of Scenedesmus rubescens was improved by 3.2-fold at the lab-scale. Scale-up was then evaluated in a 7L stirred-tank reactor under fed-batch operation, resulting in an overall productivity of 8.63 g/L/day and a maximum biomass concentration of 69.5 g/L. The protein content of S. rubescens achieved approximately 31% of dry weight, similar to Chlorella vulgaris in heterotrophy.

Summary: The antibiotic sulfamethoxazole (SMX) has been found to have biotoxic effects on Scenedesmus obliquus, an aquatic organism. Exposure to SMX promotes gene expression, leading to changes in algal cell ultrastructure. These changes include blurred cell walls, damaged chloroplast structure, and increased number and volume of mitochondria per cell. The effects of SMX on gene expression are related to inhibition of cell growth, decrease in chlorophyll content, increase in cell membrane permeability, production of reactive oxygen species, increased lipid peroxidation, and higher activities of antioxidant enzymes. The abnormal expression of non-coding RNAs may be an important mechanism underlying the carcinogenic effects of SMX.

Summary: This study investigated the combined effect of high temperatures and water withholding on the growth processes of barley and compared the response of different genotypes. The results showed that there were variations in the response to heat and drought stress among genotypes, which could be attributed to differences in anatomy, ultrastructure, and physiological and metabolic processes. Tolerant genotypes performed better in terms of physiological and biochemical indicators under stress compared to sensitive ones.

Summary: This study assessed the bioethanol efficiency of Scenedesmus acuminatus CCALA 436 and studied the effects of growing the algae in wastewater and at different concentrations of mepiquat chloride. The pre-treatment efficiencies of different concentrations of calcium oxide on the microalgae biomass were also evaluated. The findings suggest that Scenedesmus acuminatus CCALA 436 grown in wastewater and mepiquat chloride can be used for the treatment of wastewater and the production of ethanol and high-value products.

Summary: This study evaluated the food potential of Scenedesmus obliquus biomass obtained from photosynthetic cultures enriched with different concentrations of carbon dioxide (CO2). The results showed that higher concentrations of CO2 led to increased synthesis of amino acids and proteins in the cultures. In addition, higher concentrations of chlorophylls were found in cultures with higher CO2 levels, while carotenoid concentrations were higher in cultures with lower CO2 levels. Overall, the Scenedesmus obliquus biomass accumulated significant amounts of proteins, lipids, and pigments through photosynthesis.

Summary: The invasive brown seaweed Undaria pinnatifida was first recorded in Golfo Nuevo, northern Patagonia, Argentina in 1992. Since then, it has spread along the Argentine coast, forming dense seasonal kelp beds. This study aimed to investigate the temporal and ontogenetic variations of pigment content and color in Undaria from Golfo Nuevo, and their relationship with environmental factors.

Summary: The study demonstrated that Scenedesmus acutus and Chlorella pyrenoidosa are capable of effectively removing Pb2+ from water bodies, with different abilities in bioaccumulation and growth inhibition concentrations. Utilizing Fourier transform infrared spectroscopy and high-angle annular dark-field scanning transmission electron microscopy, it was found that the bioaccumulation of Pb2+ by these algae species involves intracellular localization and adsorption processes.

Summary: The study found that exposure to FC60 led to increased oxidative stress in clams, significant changes in antioxidant enzyme activities in gills, and damage to lipids and proteins in digestive glands. FC60 accumulation was higher in digestive glands compared to gills, and haemolymph parameters were slightly affected by FC60 exposure. Overall, clam gills were identified as the target tissue for FC60 toxicity, with potential long-term consequences for the organism due to damage to lipids and proteins.

Summary: Alternative chemical C6O4 has been introduced as a replacement for PFOA in industrial processes. In a recent in vitro study, C6O4 was found to significantly impact haemocyte morphology, lysosomal membrane stability, hydrolytic enzyme activity, and superoxide anion production in clam Ruditapes philippinarum, leading to chromosomal aberrations. This study sheds light on the potential effects of C6O4 on bivalve species at the cellular level.
