Enzymes as river pollutants and the response of native epilithic extracellular-enzyme activity

Environmental Pollution, 1994
Extracellular-enzyme activity was measured in three watercourses, in North East England, which received effluent from sewage-works. beta-D-glucosidase, leucine-aminopeptidase and phosphatase activities were markedly elevated in water downstream of outfalls.

Extracellular Enzymic Activity of Poultry Spoilage Bacteria

Journal of Applied Bacteriology, 1971
The extracellular enzymic activity has been studied of 224 strains of bacteria isolated mainly at 1° from spoiling chickens and turkeys and from poultry processing plants. The isolates comprised 44 strains of pigmented Pseudomonas , 57 strains of nonpigmented Pseudomonas

A between-river comparison of extracellular-enzyme activity

Microbial Ecology, 1995
River-water extracellular-enzyme activity in the lowland Rivers Ouse and Derwent, northeast England, had much in common. In both rivers, the mean enzyme activities over 15 months differed in the following order: leucine aminopeptidase > phosphatase > β-D-glucosidase > β-D-galactosi-idase and β-D-xylosidase.

Extracellular Enzyme Activity in a Willow Sewage Treatment System

Current Microbiology, 2012
This paper presents the results of studies on the activity of extra-cellular enzymes in soil-willow vegetation filter soil which is used in the post-treatment of household sewage in an onsite wastewater treatment system located in central Poland. Wastewater is discharged from the detached house by gravity into the onsite wastewater treatment system. It

Livestock manure and antibiotics alter extracellular enzyme activity

Applied Soil Ecology, 2020
Abstract 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 proteolytic enzyme activity ofHistoplasma capsulatum var.duboisii

Mycopathologia, 1996
Histoplasma capsulatum var. duboisii is the etiological agent of African histoplasmosis, an important deep mycosis in West Africa. Not much is known about the physiological properties of this fungus. This communication reports on the extracellular proteolytic enzyme activity of this fungus.
