Penicillin. III. The Stability of Penicillin in Aqueous Solution.
The instability of penicillin in aqueous solution has been known since the time of its discovery by Fleming (1929). However, beyond the general recognition that excess acidity or alkalinity caused rapid inactivation, little work has been reported on the inactivation of penicillin over a wide pH range and at different temperatures. The maximum stability range of a barium salt of penicillin teste...
متن کاملThe Decomposition of Cysteine in Aqueous Solution*
In a recent study (1) it was shown that cystine could be decomposed by boiling distilled water with the formation of cysteine, hydrogen sulfide, and elementary sulfur. The decomposition of cysteine under similar conditions should aid in a clearer explanation of the mechanisms involved in the breakdown of these two amino acids. The action of alkaline reagents on cysteine and its derivatives has ...

متن کاملPhotodegradation of the Antibiotic Penicillin G in the Aqueous Solution using UV-A Radiation
Background and purpose: Highly consumption of antibiotics and their entrance into the environment has increased concerns all over the world. These compounds enter to the environment through an incomplete metabolism and a considerable amount of them cannot be removed using usual waste filtration systems. Therefore, the present study aimed to investigate the feasibility of using ultraviolet radia...
