Flavonoids as Natural Stabilizers and Color Indicators of Ageing for Polymeric Materials
Few changes have occurred in the use of various stabilizers over recent years. In the current literature, phosphate derivatives are used as anti-ageing additives in polymers, and the most popular of these are sterically hindering cyclic amines. However, most of these compounds are carcinogenic. Synthetic phenols have been increasingly used as antioxidants in food and in polymers. Ecological sta...
متن کاملBiodegradability of biofilm extracellular polymeric substances.
This study discovered that biofilm extracellular polymeric substances (EPS) are biodegradable by their own producers and by other microorganisms when they are starved. The study was performed in a comparative fashion to examine the biodegradability of biofilm EPS by the microorganisms from the original biofilm (its own producers) and from activated sludge (other microorganisms). Four distinctiv...
متن کاملLignins as Emulsion Stabilizers
We report on the use of (kraft and soda) lignins as polymeric amphiphiles for the stabilization of emulsions. Lignins’ phase behavior in oil/water systems is presented and explained in terms of their molecular affinities. Emulsions with various oils (including crude oils) were formulated and their properties were rationalized in terms of lignin surface activity as a function of pH and salinity....
متن کاملOptimization of Carbon and Nitrogen Sources for Extracellular Polymeric Substances Production by Chryseobacterium indologenes MUT.2
Background: Bacterial Extracellular Polymeric Substances (EPS) are environmental friendly and versatile polymeric materials that are used in a wide range of industries such as: food, textile, cosmetics, and pharmaceuticals. To make the production process of the EPS cost-effective, improvements in the production yield is required which could be implemented through application of processes such a...
متن کاملExtraction of Structural Extracellular Polymeric Substances from Aerobic Granular Sludge
To evaluate and develop methodologies for the extraction of gel-forming extracellular polymeric substances (EPS), EPS from aerobic granular sludge (AGS) was extracted using six different methods (centrifugation, sonication, ethylenediaminetetraacetic acid (EDTA), formamide with sodium hydroxide (NaOH), formaldehyde with NaOH and sodium carbonate (Na2CO3) with heat and constant mixing). AGS was ...
