For MWHPO-MB, C element content increased obviously due to the adsorption of organic carbon compound, MB. Optimization of adsorbent components. Different component adsorbents usually show different adsorption performances. For the sake of comparison, MWHPO (number 1), MWHPO-GO-0.5 (number 2)...
In addition to the role that this phytohormone plays in normal development, ABA content is also in- creased in response to water deficit, preserving cell water content due to stomatal closure. In Arabidopsis, NCED5 acts in association with NCED3 to synthesize ABA under normal conditions and in...
The total sum of amino acids as determined by this method gives an intermediate value for the protein content of 46.5 ± 0.9 g/100 g. Nonetheless, this method assumes that no free amino acids are present in the raw material and relies on a protein hydrolysis step prior ...
