Phosphorus

Degradation of dissolved organic phosphorous

• Degradation of dissolved organic phosphorus (P-monoesters): Alkaline phosphatase activity (APA)
• Degradation of dissolved organic phosphorus (P-diesters): Phosphodiesterase activity (PDE)
• Degradation of dissolved organic phosphorus (phosphonates): C-P lyase activity (CLA)
• Cleavage of phosphate from 5'-nucleotides: 5'NT/5PN activity

P nutrition

• Reduction of phosphite to phosphate for growth (ptxABCD)
• 32-P incorporation
