Extracellular enzyme-clay mineral complexes: Enzyme adsorption, alteration of enzyme activity, and protection from photodegradation
@article{Tietjen2004ExtracellularEM, title={Extracellular enzyme-clay mineral complexes: Enzyme adsorption, alteration of enzyme activity, and protection from photodegradation}, author={Todd E. Tietjen and Robert G. Wetzel}, journal={Aquatic Ecology}, year={2004}, volume={37}, pages={331-339} }
Enzymes released extracellularly by micro-organisms have major functions in nutrient acquisition and organic matter degradation. Clay particles, common in many surface waters, can modify enzyme activity. Clay minerals are known to form aggregates with organic molecules, and the formation of enzyme-clay complexes could alter the level of activity. Montmorillonite clay and clay extracted from Elledge Lake (Tuscaloosa, Alabama) basin soil were combined with alkaline phosphatase, glucosidase…

It is shown that a limited availability of sorption sites is important for high specific activity and persistence of the enzymes, and that the soil mineral phase supports microorganisms in less-sorptive environments by saving energy on enzyme production.

The results suggest that the type of arsenate inhibition on free soluble ALP was competitive inhibition, whereas for immobilized and soil ALPs, the inhibition was competitive or mixed inhibition depending on the mineral or soil property.

Hydrolytic extracellular enzyme activity in heterotrophic biofilms from two contrasting streams

The oligotrophic biofilm was found to contain about twice as much extracellular esterase activity as the more eutrophic River Clywedog biofilm, although these activities also fluctuated during the colonization period.
Influence of Algal Biomass on Extracellular Enzyme Activity in River Biofilms

The relevance of algal biomass on the heterotrophic ability of biofilms may be related to the physical proximity between the two, but also to the high proportion of polymeric carbohydrates included in algal exudates and lysis products, whose use is enzyme-mediated.

The formation of clay hutches by bacteria would seem to merit further investigation, particularly regarding their roles in bacterial processes in soil and in geological processes, and the interesting possibilities that the 'clay hutches' may represent a 'soil microhabitat', a 'minimal nutritional sphere' and an 'effective survival unit' for autochthonous bacteria are noted.

Values of epiphytic enzyme activity relative to activity in pond water were substantial enough to suggest that, at well vegetated sites, epiphanic enzyme activity should make up an appreciable proportion of whole-pond extracellular enzyme activity.
