Characterization of an aggregated polymer from Penicillium sp. (PB-73 strain).
1. We describe a polymeric form of magnesium ammonium phosphate associated with linoleic acid and a basic protein produced by Penicillium sp (strain PB-73). 2. Chemical and physical data suggest a structure characterized as an aggregated polymeric form of protein magnesium ammonium phospholinoleate anhydride. 3. The aggregated polymer has an approximate molecular weight of 316 kDa and a phosphate/magnesium ratio of 2.34.
