Modeling of extracellular polymeric substances and soluble microbial products production in a submerged membrane bioreactor at various SRTs.
Extracelluar polymeric substances (EPSs) and soluble microbial products (SMPs) produced by microbial cultures involved in membrane biofouling have been widely investigated. A mathematical model of EPS and SMP formation and degradation was established based on the activated sludge model no. 1 (ASM1) and was applied to the membrane bioreactor sludge with different sludge retention times (SRTs). T...
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 کاملMicrobial Extracellular Polymeric Substances (EPSs) in Ocean Systems
Microbial cells (i.e., bacteria, archaea, microeukaryotes) in oceans secrete a diverse array of large molecules, collectively called extracellular polymeric substances (EPSs) or simply exopolymers. These secretions facilitate attachment to surfaces that lead to the formation of structured 'biofilm' communities. In open-water environments, they also lead to formation of organic colloids, and lar...
متن کاملExtracellular Polymeric Substances-wonder Macromolecules in Microbial Mats
Microorganisms play critical roles in the various aquatic systems forming microbial mats. The microbial mats are held together and bound to their substrates by slimy extracellular polymeric substances (EPS) having various applications which they secrete. They use all types of metabolism and feeding strategy that have evolved on Earth, and have shown immense use in various industrial application...
متن کاملCharacterization of extracellular polymeric substances from acidophilic microbial biofilms.
We examined the chemical composition of extracellular polymeric substances (EPS) extracted from two natural microbial pellicle biofilms growing on acid mine drainage (AMD) solutions. The EPS obtained from a mid-developmental-stage biofilm (DS1) and a mature biofilm (DS2) were qualitatively and quantitatively compared. More than twice as much EPS was derived from DS2 as from DS1 (approximately 3...
