Characterization of alkaline phosphatase activity in the North and South Pacific Subtropical Gyres: Implications for phosphorus cycling
alkaline phosphatase activity iin the North South Pacific Subtropical Gyres:phosphorus cycling
2011/4/8
We characterized alkaline phosphatase (AP) activity (APA) and report AP kinetic parameters in the North and South Pacific Subtropical Gyres (NPSG and SPSG, respectively) to evaluate the relative impor...
Alkaline phosphatase activity and regulation in the North Pacific Subtropical Gyre
Alkaline phosphatase activity regulation the North Pacific Subtropical Gyre
2010/4/17
Alkaline phosphatase (AP) activity (APA) was measured at several stations in the North Pacific Subtropical Gyre in July 2008, and in a series of nutrient addition experiments: nitrate plus ammonium (+...
Presence and regulation of alkaline phosphatase activity in eukaryotic phytoplankton from the coastal ocean: Implications for dissolved organic phosphorus remineralization
Presence and regulation alkaline phosphatase activity eukaryotic phytoplankton the coastal ocean Implications for dissolved organic phosphorus remineralization
2006/5/4
The biologically important constituents of the dissolved organic phosphorus (DOP) pool, their bioavailability, and their cycling in coastal systems are still poorly understood. Here we use the enzyme ...
Zinc availability and alkaline phosphatase activity in Emiliania huxleyi: Implications for Zn–P co-limitation in the ocean
Zinc availability alkaline phosphatase activity
2006/4/23
Zinc (Zn) serves as a cofactor in several extracellular phosphatases, which allow microorganisms to acquire
phosphorus from organic P compounds. In oligotrophic ocean water, where both phosphate and ...
Effect of ultraviolet radiation on alkaline phosphatase activity and planktonic phosphorus acquisition in Canadian boreal shield lakes
Effect of ultraviolet radiation alkaline phosphatase activity planktonic phosphorus acquisition Canadian boreal shield lakes
2005/9/13
We examined how ultraviolet radiation (UVR) affects the activity of alkaline phosphatase (APase), a common extracellular enzyme. APase activity declined up to 57% under UVR exposure and decreased more...
Experimental investigation of taxon-specific response of alkaline phosphatase activity in natural freshwater phytoplankton
taxon-specific response alkaline phosphatase activity natural freshwater phytoplankton
2003/5/20
It is widely accepted that alkaline phosphatase activity (APA) is an efficient indicator of phosphate limitation in freshwater phytoplankton communities. In this study, we investigated whether the res...
Phytoplankton phosphorus deficiency and alkaline phosphatase activity in the McMurdo Dry Valley lakes, Antarctica
Phytoplankton phosphorus deficiency alkaline phosphatase activity McMurdo Dry Valley lakes Antarctica
2001/6/9
We assessed the nutrient (N, P) deficiency of phytoplankton from the perennially ice-covered lakes in Taylor Valley, Antarctica, with 14C-based bioassays. Phytoplankton in the near-surface waters from...
