Degradation of several of the aforementioned antibiotics yields the desosamine sugar. It is found in combination with the smaller macrolide rings, always attached at C-3 or C-5 of the aglycone. Alkaline degradation found the sugar to be a D-hexose derivative. [8]
Antibiotics are widely produced and consumed to treat bacterial and fungal diseases. Since antibiotics are only partially metabolized, the non-metabolized antibiotics are released into the environment. Due to this, antibiotics are discovered in sludge, drinking water, wastewater, surface water, soil, groundwater and sediments.
Unlike the case of beta-lactam antibiotics, the inhibitors act as suicide substrates (tazobactam and sulbactam) which ultimately leads to the degradation of the beta-lactamase. [7] Avibactam on the other hand does not contain a beta-lactam ring (non beta-lactam beta-lactamase inhibitor), and instead binds reversibly .
Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g. oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline ...

Antibiotics can cause severe reactions and add significantly to the cost of care. [21] In the United States, antibiotics and anti-infectives are the leading cause of adverse effect from drugs. In a study of 32 States in 2011, antibiotics and anti-infectives accounted for nearly 24 percent of ADEs that were present on admission, and 28 percent ...
Carbenicillin is a bactericidal antibiotic belonging to the carboxypenicillin subgroup of the penicillins. [2] It was discovered by scientists at Beecham and marketed as Pyopen. It has Gram-negative coverage which includes Pseudomonas aeruginosa but limited Gram-positive coverage.
Microorganisms may be a viable solution to this issue of environmental pollution by the degradation of the xenobiotics; a process known as bioremediation. [9] Microorganisms are able to adapt to xenobiotics introduced into the environment through horizontal gene transfer , in order to make use of such compounds as energy sources. [ 8 ]
