Abstract
The invention relates to a process for improving the solubility of dry cell culture media. Some dry powder cell culture media show poor dissolving properties and result in turbid solutions when they are dissolved in aqueous solutions. Using a stepwise procedure in which the amino acids present in the non-dissolving part are identified and added to a new batch in other particle sizes significantly reduces that problem.
