The production of citric acid from lactic acid and from alcohol.
IN the dairy industry moulds are often encountered on media containing lactic acid. According to the literature on the subject, the view appears to be justified that this acid is oxidized by the moulds into CO2 or transformed into oxalic acid. Wehmer [1929] reports that by the action of Aspergillus mutantus calcium lactate is transformed into carbonate and sodium lactate into oxalate. Similarly...
متن کاملDestructive effects of citric acid, lactic acid and acetic acid on primary enamel microhardness
Objective: This study aimed to assess the destructive effects of citric acid, lactic acid and acetic acid produced from the fermentation of foods on primary teeth enamel. Methods: This in vitro, experimental study was conducted on 24 sound primary teeth. The teeth were polished with a fine abrasive paper under running water. Tooth pieces measuring 3 × 4 × 3mm were cut out of the teeth and s...
متن کاملApplication of Plackett Burman Design for Citric Acid Production from Pretreated and Untreated Wheat Straw
A solid state fermentation method was used to utilize wheat straw as substrates for citric acid production by using Aspergillus niger ATCC 9142. The Plackett Burman design (PBD) of experiments was used to test the relative importance of the variables affecting production such as moisture content, age of spore, inoculum size, initial pH of substrate, methanol conce...
متن کاملCitric acid, lactic acid and oxygen metabolism of frozen-thawed semen from four subhuman primate species.
A series of recent studies has been devoted to the systematic examination of characteristics of the semen of subhuman primates, with particular reference to the successful freeze-preservation of these specimens. Roussel & Austin (1967a) showed that trypsin will liquefy the coagulum which appears in these ejaculates without harm to the motility of the sperm cells and the survival rates of cells ...
