Determination of extractable phosphorus was modified from previous study [1 (link)]. Briefly, 5 g of each sample were mixed with 50 mL 0.2% pepsin solution, which was prepared with 0.2 g pepsin (Sigma, St. Louis, MO, USA) dissolved in 100 mL 0.1 M HCl solution. After 3 h of incubation at 37°C and 80 rpm, the mixtures were centrifuged at 3,000 rpm, followed by filtration through Advantec No.1 filter papers. The 0.3 mL extracts were added to 0.6 mL deionized water and 0.6 mL vanadium-ammonium molybdate solution, which was prepared with nitric acid, ammonium metavanadate (Sigma, USA) and ammonium molybdate tetrahydrate (Sigma, USA). Then, the mixtures were centrifuged again at 6,000 rpm for 10 min, and the absorbance of suspension was detected at 415 nm. Solutions of 0.3125 to 2.5 μmol/mL potassium dihydrogen phosphate were also detected to draw a standard curve. The 300 g WB treated with 750-unit Phy was also analyzed.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
