Phosphodiesterase activity of soils

WebThe phosphodiesterase activity of six surface soils studied ranged from 16 to 147 µg p-nitrophenol released · g⁻¹ soil · hour⁻¹. Steam sterilization and formaldehyde destroyed … Webneutral soils. As most of the organic P inputs to soil are phosphate diesters, it therefore seems likely that phosphodiesterase activity regulates labile organic P turnover in pasture soils. The low phosphodiesterase activity in acidic soils may be linked to the dominance of fungi or an effect of sorption on the enzyme.

WebThis work demonstrates that evaluating PME activity in conjunction with P fractions can be a useful framework to better understand soil P cycling. Incorporating additional variables—such as P o fractionated physically or enzymatically, and phosphodiesterase activity—into the current statistical framework may further improve understanding of ... WebIn contrast, the optimum pH for phosphodiesterase activity varied systematically with soil pH, with the most acidic pH optima (3.0) in the most acidic soils and the most alkaline pH optima (pH 10) in near-neutral soils. Arylsulfatase activity had a very acidic optimum pH in all soils (pH ≤3.0) irrespective of soil pH. tsc sprayer tank https://coyodywoodcraft.com
