- Abstract:
- ... Extracellular polymeric substances (EPS) play significant roles in protecting cells against environmental stresses. However, little information is known about the roles of different EPS in these processes. In this study, the productions and physicochemical characterizations of soluble-EPS (S-EPS) and bound-EPS (B-EPS), the two different fractions of EPS from a green alga Chlorella vulgaris under t ...

- Abstract:
- ... The packaging-food partition coefficient (Kₚf) is a key parameter to estimate the chemical migration from packaging to food and resulting ingestion exposures. As a particular case of Kₚf, the solid material-water partition coefficient (Kₘw) is also important in relating the material to the water phase-based skin permeation coefficient to further assess dermal contact exposure to chemicals in solid ...

This study focused on the effects of activated carbon on SCFAs production from algae during alkaline anaerobic fermentation. When activated carbon was present at 0.5 g/L, the maximum production of SCFAs was 4875 mg COD/L, which was nearly 2.4 times that of the control (2026 mg/L). Mo ...

YF1 revealed that the denitrification rate decreased markedly from 99.8%, 98.0%, 68.7% to 16.3% when the concentrations of Cu(II) rose from 0, 0.01 mM, 0.05 mM to 0.1 mM, respectively. This outcome was confirmed by the successful test of OD₆₀₀, total protein and enzyme activities. As the concentration of Cu(II) increased fr ...

Vegetation has unavoidably affected the temperature by altering surface properties, while the magnitude of this effect has remained unknown. This study aimed to investigate the patterns of global Ts-Ta and quantify the contribution of vegetation change. Trend analysis, correlation ...

Using a probabilistic material flow analysis model, we investigate the mass balance and occurrence of nano-silver in the environment of Hunan, renowned as “the home to non-ferrous metals” in China. The model builds on China-specific production and environmental information and incorporates sulfidation of nano-silver in urban wastewater treatment systems. We predict that the bulk of nano-silver (>9 ...
