Activity of extracellular enzymes on the marine beach differing in the level of antropopressure
Environmental Monitoring and Assessment, 2016The level of activity of extracellular enzymes was determined on two transects characterised by different anthropic pressure on a sandy beach in Ustka, the southern coast of the Baltic Sea. Generally, the level of activity of the studied enzymes was higher on the transect characterised by high anthropic pressure.

Role of the Extracellular Matrix: Enzyme Activities and Metastasis
2013The local milieu of malignant tumor cells has key roles in cancer progression. A major component of the niche is the extracellular matrix (ECM), a complex interdigitating meshwork of macromolecules with multiple biophysical and biochemical characteristics.

Influence of Algal Biomass on Extracellular Enzyme Activity in River Biofilms
Microbial Ecology, 2000Relationships between biofilm structural components (algal and bacterial biomass) and the activities of some extracellular enzymes that contribute to the ability to degrade organic matter) were explored for six Atlantic and three Mediterranean streams and rivers.

Soil extracellular enzyme activity and stoichiometry in China's forests
Functional Ecology, 2020Abstract Ecoenzymatic stoichiometry links microbial decomposition with nutrient mineralization and improves our understanding of nutrient cycling in terrestrial ecosystems. Microbial C:N:P acquisition in the topsoil converged at a ratio of 1:1:1 in global ecosystems.

Livestock manure and antibiotics alter extracellular enzyme activity
Applied Soil Ecology, 2020Abstract Soil enzyme activities are commonly used for inferring microbial processes and nutrient limitations. In agroecosystems these enzymes can also be used to determine management effects on soil quality. Here we report the effect of dairy manure inputs and veterinary antibiotics (cephapirin and pirlimycin) on soil enzyme activities, using both a ...

Extracellular enzyme activities during cassava fermentation for ?fufu? production
World Journal of Microbiology & Biotechnology, 1992Amylase and pectin methyl esterase activities increased rapidly during the early period of the fermentation of cassava for 'fufu' production, attaining their peak activities after 12 and 24h, respectively. Cellulase activity was lower and approximately constant for most of the fermentation period.

Enzyme Activation and Liberation: Intracellular/Extracellular Events
1987The exocrine pancreas is a highly active site of protein synthesis. Most of the proteins consist of digestive enzymes destined for export from the acinar cell and in normal human pancreatic juice, as in other species, they constitute about 90% of the total proteins of the juice [1]. In the remaining 10% we identified serum proteins accounting for 3% of

Temperature Sensitivity of Intracellular and Extracellular Soil Enzyme Activities
2021<p>Predicting the pattern of soil organic matter (SOM) decomposition as a feedback to climate change, via release of CO<sub>2</sub>, is extremely complex and has received much attention. However, investigations often do not differentiate between the extracellular and intracellular processes involved and work is

Extracellular Fungal Hydrolytic Enzyme Activity
2005Plant biomass is largely composed of an intricate assembly of polymeric carbohydrates and lignin. Efficient degradation by fungi and other microorganisms requires a suite of extracellular enzymes capable of degrading the polymeric cell wall fractions into monomers, which can then be assimilated by microbes.

Extracellular Enzyme Activity in Eutrophic and Polyhumic Lakes
1991For many years, the synthesis, secretion, and activity of extracellular enzymes of different organisms have been intensively studied by workers in many different disciplines, such as applied microbiology, biotechnology, biochemistry, and medicine (Pollock, 1962; Priest, 1977; 1984; Kreutzberg et al., 1986; Chaloupka and Krumphanzl, 1987).
