Summary: This paper investigates the bifurcation phenomena that can occur in a continuous bioreactor for lipid-rich biomass production using Rhodococcus opacus. The study develops an unstructured model of the bioreactor based on validated experimental studies, and carries out analytical and numerical analysis of the model. The results show that the inhibition effect of biomass growth rate can lead to static bistability, and periodic behavior is also observed for certain model parameters. The analysis also explores the impact of model parameters on bioreactor productivity, and helps in identifying unsafe operating regions to mitigate operational problems.

Summary: This study examines the colonization of microorganisms on polyethylene microplastics and their ability to accumulate organic pollutants, as well as the impact of pollutants on biofilm development. The results show that Pseudomonas aeruginosa can form strong biofilms on microplastics, with fluorescent blue microplastics having the highest protein content. The presence of organic contaminants decreases cell viability on white microplastics, while the overall effect on biofilm formation is negligible. Microbial colonization influences the ability of microplastics to accumulate contaminants, with fluorescent blue microplastics showing the highest sorption capacity.

Summary: Aging is associated with chronic low-grade inflammation that affects physiological function, with the liver playing a key role in regulating systemic inflammation. Increased accumulation of hepatic macrophages in the liver with age contributes to heightened expression of inflammatory cytokines, such as TNF-alpha and IL-6. Targeting macrophages and IL-6 may hold promise for treating age-related diseases and promoting healthy aging by attenuating the deleterious reprogramming of macrophage function.

Summary: In this study, the effects of caffeine and functionalized multi-walled carbon nanotubes on clams were evaluated at different temperature levels. The results showed negative impact of these compounds at the control temperature, with a decrease in protein content and metabolism. The biotransformation capacity at 18 degrees Celsius may explain the lower caffeine concentration observed and differences among treatments were less evident at the increased temperature level.

Summary: This study investigates the impact of different sizes, surface functionalization, and concentrations of polystyrene microplastics (PS MP) on plants. The results show that with increasing PS concentration, there is a decline in plant growth and an increase in oxidative stress. The effect is more significant for 12 um PS, possibly due to its larger size and adherence to roots causing mechanical damage. Moreover, microplastics with a negative surface charge are less toxic than uncharged or positively charged 1 um PS. Overall, the impact of microplastics on plants is determined by multiple factors such as size, charge, and concentration.

Summary: During the COVID-19 pandemic, improper disposal of face masks has led to them becoming a significant source of microplastics and nano plastics in the environment. This study quantified and characterized the microplastics released from different layers of masks and investigated their effects on two algal species. The results showed negative impacts on cell viability, photosynthetic yield, and electron transport rate, as well as increased oxidative stress markers and antioxidant enzyme levels. Optical microscopy and FTIR spectroscopy confirmed morphological and chemical changes in the algae. The study highlights the environmental risks posed by microplastics released from surgical face masks and emphasizes the need for further research on their impacts.

Summary: Seven novel compounds were extracted from the ethyl acetate extract of a novel marine bacterium Bacillus licheniformis, which were identified using GC-MS. One bioactive compound with potent antibacterial activity was virtually screened and found to satisfy Lipinski's rule, making it suitable for preventing infection by A. hydrophila and V. parahemolyticus. Molecular docking and dynamics simulations showed strong binding efficacy of the bioactive compound against the core proteins of the two pathogens. In vitro toxicity analysis revealed the non-toxic nature of the ethyl acetate extract. Thus, the bioactive compound of B. licheniformis was proven to be a potent antibacterial agent against A. hydrophila and V. parahemolyticus.

Summary: Due to the escalating risk of plastic pollution, nanoplastics have received significant attention. A study examined the individual and combined effects of fluorescent polystyrene nanoplastics (FNPs) and diclofenac (DCF) on Scenedesmus obliquus. The toxicity of S. obliquus significantly increased upon exposure to DCF and FNPs, with oxidative stress being the major cause. When FNPs and DCF were mixed, a synergistic or antagonistic effect was observed depending on the concentrations. Oxidative stress parameters, antioxidant enzyme activity, and pigment content in the algae validated the cytotoxicity data. The study highlights the hazardous nature of nanoplastics and their co-exposure risks with pharmaceuticals.
