Azelaic Acid Utilization by a Pseudomonas

THE METABOLISM OF AZELAIC ACID* BY H. GREGG SMITHt

The evidence concerning the utilization of dibasic fatty acids in the animal organism has been reviewed by Dakin (3) and more recently by Flaschentrager (4). Oxalic acid is burned to a limited extent, and in large amounts is toxic. Malonic and succinic acids are utilized, and glutaric acid is completely oxidized in the dog (3), but is nephrotoxic to the rabbit, while the higher acids affect the...

The Utilization of Pseudomonas taetrolens to Produce Lactobionic Acid

Lactobionic acid is a relatively new product derived from lactose oxidation, with high potential applications as a bioactive compound. Conducted experiments confirmed that both the time and temperature influenced the production of lactobionic acid during bioconversion of lactose using the Pseudomonas taetrolens bacteria. The study also investigated the effect of inoculum concentration on the pr...

Utilization of a Stable Isotope of Oxygen by Pseudomonas Fluorescens.

Oxygen utilization is defined in this investigation as the terminal use of oxygen in respiration, i.e., the formation of water. A culture of Pseudomonas fluorescens was allowed to respire in an atmosphere of O(18). The production of H(2)O(18) was measured during two test runs of 124 and 232 min each. During the first run, 0.505 mmole of H(2)O(18) was produced. The second run produced 0.460 mmol...

Pretreatment with ultrasonication reduces the size of azelaic acid-chitosan nanoparticles prepared by electrospray

Nowadays, electrospray is becoming a favourable approach for preparing monodispersed nanoparticles. However, this approach is quite recent and requires further works to optimize control over physicochemical properties of its products. This study aimed to determine the possible effects of sonication as a pretreatment to reduce the size of azelaic acid-chitosan particle before using electrospray....
