A detergent for cleaning iron monosulfide was formulated with surfactant, diamino-propadiene, citric and EDTA, and its cleaning mechanism was discussed.
With cellulose hydrolyte as raw material to ferment citric acid by Aspergillus niger at constant temperature and under oscillation temperature were discussed and compared.
This articl analyzes the current situation of fermentation tank for citric acid production in China and introduces the successfully developed spraying ring type aerophile fermentation tank.
Your cells make citric acid as part of the process that turns everything that you eat —carbohydrates, proteins, and fats — into energy and carbon dioxide.
So citric acid is mass-produced much like xanthan gum and carrageenan are, but instead of being pooped out by bacteria, or mulched out of seaweed, it's excreted by mold.
A black fungus known as aspergillus, which ironically enough is the same stuff that grows on spoiled food, produces citric acid when it metabolizes sugar in a low oxygen environment.
The citric acid gets put into the citric acid cycle, also known as the TCA cycle, or the Krebs cycle... or just as that thing everybody hates memorizing for bio class.
So we've been partnering with companies that are taking waste CO2 and transforming it into a useful family of chemicals like oxalic acid or citric acid, the same one you use in orange juice.
因此,我们一直在与一些公司合作,这些公司正在收集废弃的 CO2 并将其转为有用的学物质,例如草酸或柠檬酸,与您在橙汁中使用的物质相同。
