Application


  • Chitoporin from Serratia marcescens: recombinant expression, purification and crystallization.: This study details the application of ammonium phosphate monobasic in the crystallization of chitoporin from Serratia marcescens. The results provide insights into the structural biology of this protein, which is significant for understanding its function and potential applications in biotechnology (Amornloetwattana et al., 2020).



General description

Ammonium phosphate monobasic (APM) is an inorganic salt widely used in fertilizer, baking powder and yeast production. It is also employed as an agent to control pH of a solution and in corrosion inhibition. APM can be prepared by reacting phosphoric acid with anhydrous ammonia maintaining the pH below 5.8. The change in some of the physical characteristics on its addition to a high carbonate containing unfired and fired illitic shale has been studied.
