Microbial production of citric acid [PDF]
Brazilian Archives of Biology and Technology, 1999 Citric acid is the most important organic acid produced in tonnage and is extensively used in food and pharmaceutical industries. It is produced mainly by submerged fermentation using Aspergillus niger or Candida sp. from different sources of carbohydrates, such as molasses and starch based media. However, other fermentation techniques, e.g.

Discovery of a second citric acid cycle complex
Heliyon, 2023 Together, Nobel Prize honoured work, mathematics, physics and the laws of nature have drawn a concept of clockwise cycling carboxylic acids in Krebs’ Citric Acid Cycle. A Citric Acid Cycle complex is defined by specific substrate, product and regulation.

Investigating matrix interference in the pharmacopeial limit test for aluminum in citric acid: a re-examination, for revision of the method [PDF]
Pharmacia, 2022 In many pharmacopoeias, the limit test used for determining the level of aluminum in citric acid labeled for use in the manufacture of dialysate, is based on solvent extraction using 8-hydroxyquinoline and measurement of fluorescence.
