“…Differences in b-glucosidase corresponded to differences in total carbon concentrations (Table 1), but also to microbial biomass concentrations, at least as indicated by microbial phosphorus (Table 2), with higher b-glucosidase activity in soils with high total carbon and microbial biomass. This agrees with the close correlation between b-glucosidase and total and microbial carbon in temperate pasture soils (Turner et al, 2002). Factors regulating the differences in N-acetyl-glucosaminidase activity among the three soils are less obvious, but may relate to either microbial demand for nitrogen (Olander and Vitousek, 2000) or the general activity of the fungal community (Miller et al, 1998).…”

“…Whalen, 2005), methane production was 60 greater in the wet treatment at each season measured. This was expected due to methane 61 production primarily being an anaerobic process (Segers, 1998, Whalen, 2005; where the anarobic 62 conditions reduce the consumption of methane by methanotrophic bacteria, resulting in an increase 63 in methane released to the atmosphere (Pearce and Clymo, 2001 The greater BG activity in the dry treatment might suggest increased degradation of cellulose within 67 these soil conditions as a result of increasing microbial biomass (Turner et al, 2002) (Rudaz et al, 1991) and longer in other studies. In the microcosms, 83…”

The biological effects caused by the interactions of these pressures are poorly understood, particularly on soil processes. We used a mesocosm experiment and laboratory assays to study the impact of lowered water tables, groundwater nitrogen contamination, and their synergistic effects on soil microbial processes and greenhouse gas emissions. This study showed that just a 10 cm decrease in water table depth led to a reduction in denitrification and to a corresponding increase in soil nitrogen content. Meanwhile N2O emissions occurred for longer durations within dune slack soils subject to higher concentrations of groundwater nitrogen contamination. The results from extracellular enzyme assays suggest that decomposition rates increase within drier soils shown by the increase in β-glucosidase activity, with further sensitivity to groundwater nitrogen contamination shown by the increase in phenol oxidase activity. Dune slack soils with a 10 cm lower water table had signific...

“…Therefore, Kumari et al, (2016) supported the views that consortia with broad enzymatic capacities are more effective in the degradation of hydrocarbons in soil environment. β-Glucosidase activity (BGA) in soil might be particularly useful for soil quality monitoring because of the central role of this enzyme in soil organic matter cycling, which is generally regarded as an important component of soil quality (Turner et al, 2002) In the present study, crude oil contamination did not affected negatively. The contamination with crude oil increased the amount of total organic and water-soluble C. Some compounds within these fractions may serve as energy sources for microbial populations (Bastida et al, 2016).…”

Crude oil affects soil ecosystems, resulting in significant losses in soil quality. The objective of the present study was to evaluate the effects of hydrocarbon pollution (crude oil) on soil enzyme activities and determine the removal of total petroleum hydrocarbons (TPH) during an incubation period of 150 days. The potential use of wastewater sludge as a biostimulating agent in petroleum-contaminated soils was also evaluated. The degradation of crude oil in contaminated soil was significantly enhanced after the addition of wastewater sludge.The results also indicated that significant TPH degradation in crude oil-contaminated soils (80% for dose of 0.5% and 83% for dose of 5% at 18 °C) (94% for dose of 0.5% and 92% for dose of 5% at 28 °C) occurred after an incubation period of 150 days. Enhanced enzyme activity levels in contaminated soils indicated that crude oil (0.5% and 5%, w/w) stimulated microbial growth and enzyme activity in the soil environment. Urease activity (UA) levels in crude oil contaminated soils were generally higher than initial UA levels in soil during the incubation period. Soil UA exhibited a stronger response to petroleum treatment. Alkaline phosphatase (APA) and β-Glucosidase (BGA) activities were not affected crude oil pollution. However, contamination of crude oil had a negatively effect on soil dehydrogenase activity (DHA).
