Citric acid fermentation – biotechnological problems and possibilities of computer control. Citric acid today is produced almost exclusively by fermentation with the mold Aspergillus niger according to the surface or submerged process. The application of complex raw materials, like molasses, gives rise ...

aThe method involves the ability of certain weak hydroxycarboxylic acids (citric acid is preferred) to form polybasic acid chelates with various metal ions. These chelates can undergo polyesterification when heated in a polyhydroxyl alcohol to form a polymeric glass which has cations uniformly distribu...

also helps to neutralize the acidic environment of the vaginal tract and thus helps in prolonging the life span of the sperm. The prostatic secretion consists of alkaline phosphatase, citric acid, prostate-specific antigen (PSA), and proteolytic enzymes. The male hormone, testosterone, is necessary...
Don’t chuck out all your citric acid-containing polishes! 2. Contamination of Arminex base in general Mentality’s current suspect is cross-contamination with methacrylates. For more specifics scroll down to the Methacrylate Contamination section below. For all faulty Arminex base theories: ...
Estimate the pKavalue of propionic acid, a food preservative. Oxygen shows the same hybridization effect on acidity as carbon and nitrogen. Each structure below loses an H+from its positively charged oxygen, resulting in a neutral oxygen. One of the structures has a pKaof −3.2, while the ...
