Abstract BACKGROUND Upflow anaerobic sludge blanket (UASB) reactors are widely used in low‐ and middle‐income countries, but secondary effluents may still contain organic micropollutants and residual toxicity. This study evaluated UV–Vis photolysis and UV/H2O2 as post‐treatment options for UASB secondary effluent (SE), integrating micropollutant ...

Micellar and Solubilization Properties of Biological Surfactant Surfactin
ABSTRACT We studied aqueous solutions of surfactin in the concentration range of 0.001–200 g/L using NMR diffusometry, tensometry and optical microscopy methods. According to tensometry data, the system forms monolayers of surfactant molecules at the water‐air phase boundary at C = 0.02 g/L.

Materials and main results of the study. ABSTRACT Surfactant–polymer (SP) flooding is a promising Enhanced Oil Recovery (EOR) technique, combining improved displacement from surfactants with enhanced sweep efficiency from polymers. This study investigates two SP systems based on the biopolymer scleroxanthan (a blend of sclerotium gum and xanthan gum ...

Abstract Background This study evaluated the antimicrobial activity of thyme essential oil (TEO) encapsulated in electrospun zein fibers for use in bilayer films as active packaging for cherry tomatoes. The antimicrobial activity of TEO and bilayer films with 20%, 40%, and 60% TEO was assessed with agar diffusion and microatmosphere assays.
