Precipitates are known to occur, with time, in plant tissue culture media. The precipitates have been analyzed. They are composed of small pale yellow-white particles. Analysis of precipitates indicated a predominance of iron, phosphate, and zinc. The probable cause of the precipitates is the inevitable oxidation of ferrous ions to ferric ions and the presence of unchelated ferric ions. When the solubility of ferric phosphate is exceeded precipitation occurs. There are no reports of detrimental effects on growth and development in plant tissue culture due to the precipitates.
We would not suggest autoclaving the media, because a precipitate may form. It is advisable to add pre-autoclaved water as it contains less oxygen; this reduces the likelihood of oxidation of ferrous to ferric ions.
