The Degree of Acidity Factor and Nutrients

pH is one important factor in the life of marine algae, as well as other factors. According to US-EPA (1973) in Iksan (2005) maximum pH range for the life of marine organisms is 6.5 to 8.5. Chapman (1962) in supit (1989) states that almost the entire algal like a pH range of 6.8 to 9.6 so that the pH is ...

Elements Iron and Sodium

In plants, algae iron acts as a constituent of cytochrome and chlorophyll, as well as act as enzyme systems, and electron transfer in photosynthesis, excessive iron levels greatly inhibit the fixation of other elements (Effendi, 2000). Iron also plays a role in the oxidation-reduction in the process of photosynthesis and respiration in addition to a few enzyme cofactor in plants ...
