Diverse Corals Bioerosion Escalates Palau's Low-pH Waters
2015/6/18
As the ocean absorbs atmospheric carbon dioxide released by the burning of fossil fuels, its chemistry is changing. The carbon dioxide, which is the primary greenhouse gas responsible for global warmi...
The effect of pH on the uptake of zinc and cadmium in marine phytoplankton: Possible role of weak complexes
The effect of pH on the uptake zinc cadmium marine phytoplankton Possible role of weak complexes
2014/4/2
In natural samples from the New Jersey coast and the Gulf of Alaska, zinc (Zn) and cadmium (Cd) uptake rates by phytoplankton decreased on average about 30%as pH was decreased from 8.5 to 7.9 or 7.7, ...
螺旋藻培养中碳源和PH值的调控方法
培养 pH值 碳源 螺旋藻
2008/10/14
该发明公开了一种螺旋藻培养中碳源和pH值的调控方法。其特征是：测得螺旋藻培养的pH值达到10.3，向培养液中添加NaHCO_3或CO_2，将pH值降低。在培养过程中，反复操作，将pH值控制在10.0-10.3。同时实现对碳源和pH值的调控，以NaHCO_3为碳源，将NaHCO_3用水溶解，形成溶液，再将NaHCO_3溶液加入培养液；以CO_2为碳源，将塑料微孔管置于培养池底部，利用置于培养池底部的...
