Transparent exopolymer particles (TEP) in aquatic environments
Since the development of methods to quantify transparent exopolymer particles (TEP) 1993, it has been shown that these gel-particles are not only ubiquitous and abundant, but also play a significant role in the biogeochemical cycling of elements and the structuring of food webs. TEP may be quantified either microscopically or colorimetrically. Although data based on measurements using one or ot...
متن کاملAscending marine particles: Significance of transparent exopolymer particles (TEP) in the upper ocean
The high abundance of transparent exopolymer particles (TEP) in marine and freshwater greatly affects particle dynamics. TEP act as glue for colliding particles and form the matrix in aggregates, thereby altering aggregation dynamics. We studied the sinking behavior of freshly produced, particle-free TEP and of aggregates composed of TEP and latex spheres in a laboratory using water collected f...
متن کاملProduction of transparent exopolymer particles (TEP) by phyto- and bacterioplankton
Transparent exopolymer particles (TEP) exist abundantly in oceans and lakes and have been found to play an important role in sedimentation and biochemical cycling of matter. However, the origin of these particles and the factors regulating their formation are not well understood. This study examined several strains of algae and bacteria with respect to their production of TEP or TEP precursors....
متن کاملProchlorococcus as a Possible Source for Transparent Exopolymer Particles (TEP)
Transparent exopolymer particles (TEP), usually associated with phytoplankton blooms, promote the formation of marine aggregates. Their exportation to deep waters is considered a key component of the biological carbon pump. Here, we explored the role of solar radiation and picocyanobacteria in the formation of TEP in oligotrophic surface waters of the Atlantic and Pacific Oceans in ten on-deck ...
متن کاملNew insights into transparent exopolymer particles (TEP) formation from precursor materials at various Na+/Ca2+ ratios
Transparent exopolymer particles (TEP) are planktonic, organic microgels which play significant roles in cycling of carbon and trace elements, aggregation of particles, feeding and accommodating microbes as well as development of biofilms. However, few studies are available on the mechanism of TEP formation in various water environments. Here we investigate the formation of TEP with alginate bl...
