Summary: This study aimed to produce marine bacterial exopolysaccharides (EPS) as biodegradable and nontoxic biopolymers that can compete with synthetic derivatives. The most potent isolate, Bacillus para-licheniformis ND2, was identified through genetic analysis. The optimization conditions for EPS production were determined using Plackett-Burman design, resulting in a 1.26-fold increase in EPS yield compared to the basal conditions. Two purified EPSs, NRF1 and NRF2, were obtained and characterized. The EPSs showed antibacterial activity and induced proinflammatory cytokine expression.

Summary: In this study, a low-consumption water purification system was constructed using a new dual-reaction-center catalyst (Mo-ZnS, MZS) with a confined nonequilibrium surface. The substitution of Mo for ZnS lattice enabled the Mo site to efficiently trap emerging contaminants (ECs) and transfer the electrons to the nonequilibrium surface through the oriented interface process (Mo-S-Zn bond bridge). The system utilized natural dissolved oxygen (DO) to generate hydrogen peroxide (H2O2) under trace H2O2 trigger without the need for light and electricity assistance, achieving a high yield of H2O2 and complete removal of ECs within 60 minutes.

Summary: The synthesis of pure and Ag and Ce dual-doped ZnO NPs was achieved through a green and facile method, and their cytotoxicity in breast cancer cells and normal cells was studied. The nanoparticles exhibited a hexagonal structure, spherical shape, and smooth surfaces, with Ag and Ce evenly distributed in ZnO. Cytotoxicity experiments showed that the dual-doped NPs had a significantly greater impact on breast cancer cells compared to pure NPs, while both types had no effect on normal cells. Additionally, the antimicrobial activity against harmful bacteria was investigated.

Summary: Biohydrogen production from microalgae is being intensively researched as a potential alternative energy source. Traditional modelling and optimization methods are inaccurate and costly, so machine learning algorithms have been employed to predict nonlinear interactions and handle multivariate data. This review focuses on the recent applications of machine learning techniques, such as random forests, artificial neural networks, support vector machines, and regression algorithms, in microalgal biohydrogen production. Despite the limitations of complex and nonlinear data sets, these techniques have shown great performance, although overfitting remains a challenge.

Summary: The co-cultivation of green algae Asterococcus limneticus WL2 and phytohormone producing Streptomyces rosealbus MTTC 12951 was conducted to study the production of indole-3-acetic acid (IAA) and its precursors. The co-cultivation exhibited increased hormonal activity due to symbiotic interaction between Streptomyces and microalgae. Compared to monocultivation, co-cultivation resulted in 52% and 83% higher production of tryptophan and IAA in the extracellular space, respectively. The co-cultivation strategy also led to increased biomass and lipid productivity of microalgae.

Summary: This study aimed to optimize the removal process of Azithromycin (Azi) from the aquatic environment using CoFe2O4/NiO nanoparticles anchored onto microalgae-derived nitrogen-doped porous activated carbon (N-PAC), and develop a colorimetric method for swift Azi monitoring in pharmaceutical products. The adsorption studies showed that 98.5% of Azi in aqueous media could be removed by CoFe2O4/NiO@N-PAC, which followed second-order reaction kinetics with a maximum adsorption capacity of 2000 mg/g. Thermodynamic modeling indicated the spontaneous and exothermic nature of the adsorption process. The colorimetric Azi detection using Coomassie Brilliant Blue G-250 (CBBG-250) reagent exhibited good selectivity and a detection limit of 0.94 μM.

Summary: This study compares the effects of two types of cobalt-based nanoparticles on lung cells and finds that cobalt nanoparticles are more toxic to cells than cobalt-iron oxide nanoparticles, possibly due to the higher release of Co2+ ions by cobalt nanoparticles. Additionally, the study suggests that CalceinAM alone is insufficient to assess the toxicity of cobalt-based nanoparticles, and other methods should be used for further confirmation.

The mathematical structure for computing the impacts of fluid viscoelasticity on the flow is provided, and the dimensionless variables influencing the interaction between the fluid and structure are identified. The results show that the converging and diverging sections of the channel are affected similarly by the inertial forces and channel opening. Longer strain delaying time and shorter stress relaxation phase improve the velocity profile of the fluid flow.
