Extracellular enzyme activities of dermatophytes and yeast isolates on solid media

Mycoses, 1997
Summary. A total of 123 isolates of 14 species of dermatophytes and yeasts were screened for the activity of five extracellular enzymes including elastase, keratinase, protease (gelatinase), lipase and phospholipase, by using solid media. The optimal production and activity of each enzyme was determined with regard to different pH and temperatures ...

Activity of extracellular enzymes on the marine beach differing in the level of antropopressure

Environmental Monitoring and Assessment, 2016
The 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.

Extracellular enzyme activity associated with suspended matter in the River Rhine

Freshwater Biology, 1991
SUMMARY. 1. Spatial and temporal variations in exoenzymatic proteolysis and alkaline phosphatase activity in the River Rhine were measured fluorometrically using L‐leucyi (ß‐naphthylamide and methylumbelliferyl phosphate (MUFP), respectively, as test substances.2.

Influence of Algal Biomass on Extracellular Enzyme Activity in River Biofilms

Microbial Ecology, 2000
Relationships 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, 2020
Abstract 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.

Extracellular enzyme activities during cassava fermentation for ?fufu? production

World Journal of Microbiology & Biotechnology, 1992
Amylase 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.

Role of the Extracellular Matrix: Enzyme Activities and Metastasis

2013
The 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.

Enzyme Activation and Liberation: Intracellular/Extracellular Events

1987
The 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

2005
Plant 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.
