TL;DR: A study of the effects of various soil pretreatments on soil arylsulfatase activity showed that storage at − 10C is a satisfactory method of preserving field-moist soil samples for assay of aryl sulfase activity as discussed by the authors.
Abstract: A study of the effects of various soil pretreatments on soil arylsulfatase activity showed that storage at — 10C is a satisfactory method of preserving field-moist soil samples for assay of arylsulfatase activity. Storage of field-moist soils at 5C or 22-24C for 3 months led to a decrease in arylsulfatase activity (average, 8% at 5C, 18% at 22-24C), but storage at — 10C for the same period did not significantly affect this activity. Air-drying of field-moist soils at 22-24C caused a marked increase in arylsulfatase activity (average, 43% ), and ovendrying (105C) caused a marked decrease (average, 54%). A slow decrease in arylsulfatase activity was observed when air-dried soils were stored at 22-24C. Arylsulfatase activity decreased markedly with depth in six soil profiles examined. This decrease was associated with a decrease in organic matter content, and studies with surface soils differing markedly in physical and chemical properties showed that soil arylsulfatase activity was significantly correlated with soil organic matter content. Soil arylsulfatases were not deactivated by most of the reagents used to study the sulfur status of soils. Additional

TL;DR: The overall results seem to confirm that no direct cause-effect relationships can be derived between the changes of a soil in response to a given factor and both the variations of the activity and the behaviour of the enzymes in soil.

TL;DR: In this paper, the authors investigated the effect of residue management on the activity of a number of enzymes, including acid phosphatases, alkaline phosphatase, phosphodiesterase, and arylsulfatase.
Abstract: This study was carried out to investigate the effect of tillage and residue management on activities of phosphatases (acid phosphatase, alkaline phosphatase, phosphodiesterase, and inorganic pyrophosphatase) and arylsulfatase. The land treatments included three tillage systems (no-till, chisel plow, and moldboard plow) in combination with corn residue placements in four replications. The activities of these enzymes in no-till/double mulch were significantly greater than those in the other treatments studied, including no-till/bare, no-till/normal, chisel/normal, chisel/mulch, moldboard/normal, and moldboard/mulch. The effect of mulching on activities of phosphatases was not as significant as on activities of arylsulfatase. The lowest enzyme activities were found in soil samples form no-till/bare and moldboard/normal treatments, with the exception of inorganic pyrophosphatase, which showed the lowest activity in no-till/bare only. Among the same residue placements, no-till and chisel plow showed comparable arylsulfatase activity, whereas the use of moldboard plow resulted in much lower arylsulfatase activity. The activities of phosphatases and arylsulfatase were significantly correlated with organic C in the 40 soil samples studies, with r values ranging from 0.71*** to 0.92***. The activities of alkaline phosphatase, phosphodiesterase, and arylsulfatase were significantly correlated with soil pH, with r values of 0.85***, 0.78***, and 0.77***, respectively, in the 28 surface soil samples studied, but acid phosphatase and inorganic pyrophosphatase activities were not significantly correlated with soil pH. The activities of phosphatases and arylsulfatase decreased markedly with increasing soil depth and this decrease was associated with a decrease in organic C content. The activities of these enzymes were also significantly intercorrelated, with r values ranging from 0.50*** to 0.92***.

TL;DR: Three soils (i.e. a Belgian soil, B-BT, a German soil, G, and an Italian agricultural soil, I-BT) with different properties and hydrocarbon-pollution history with regard to their potential to degrade phenanthrene were investigated and the presence of common bands of microbial species in the cultures and in the native soil DNA indicated that those strains could be potential in situ Phenanthrene degraders.

TL;DR: In this paper, the effects of burning and N fertilization varied among the enzymes and the time of sampling, and the results showed that long-term burning significantly reduced MBC and MBN relative to the unburned-unfertilized treatment.
Abstract: Microbial biomass and enzyme activities are affected by management practices and can be used as sensitive indicators of ecological stability. Microbial biomass C (MBC), microbial biomass N (MBN) and eight enzyme activities involved in the cycling of C, N, P and S were studied in the surface (0–5 cm) of an Irwin silty clay loam soil (fine, mixed, mesic, Pachic Arguistoll) in a tallgrass prairie ecosystem. Treatments of annual spring burning and N fertilization were initiated in 1986 and encompassed: (1) unburned–unfertilized, (2) burned–unfertilized, (3) burned–fertilized, and (4) unburned–fertilized. Activities of dehydrogenase, β-glucosidase, urease, deaminase, denitrifying enzyme, acid phosphatase, alkaline phosphatase, and arylsulfatase were assayed. Long-term burning and N fertilization of the tallgrass prairie soil reduced MBC and MBN relative to the unburned–unfertilized treatment. The effects of burning and N fertilization varied among the enzymes and the time of sampling. Long-term burning significantly (P
