Cell Growth of Wall-Free L-Form Bacteria Is Limited by Oxidative Damage
The peptidoglycan (PG) cell wall is a defining feature of the bacterial lineage and an important target for antibiotics, such as β-lactams and glycopeptides. Nevertheless, many bacteria are capable of switching into a cell-wall-deficient state, called the "L-form" [1-3]. These variants have been classically identified as antibiotic-resistant forms in association with a wide range of infectious ...
متن کاملEnhancement of Pseudomonas Aeruginosa Growth and Rhamnolipid Production Using Iron-Silica Nanoparticles in Low-Cost Medium
The application of iron-silica (Fe-Si) nanoparticles for the enhancement of the Pseudomonas aeruginosa growth and rhamnolipid production in molasses medium was studied. The experiments were designed based on the response surface method (RSM) to optimize growth and rhamnolipid production. The concentration of nanoparticles and the time required to add nanoparticles to culture medium were conside...
متن کاملInduction of L-form Bacteria from Bacillus thuringiensis
Induction of L-form bacteria from Bacillus thuringiensis was investigated with the long-term view of their use as targeted biological control agents within plants. L-forms were successfully induced from B. thuringiensis subspecies israelensis 36-3 by preparing pour plates of exponential cultures in L-phase medium (LPM) containing 175 g ml -1 cephalosporin C. The induced L-forms were then subcul...
متن کاملL-form bacteria, chronic diseases and the origins of life
The peptidoglycan cell wall is widely conserved across the bacterial domain, suggesting that it appeared early in the evolution of bacteria. It is normally essential but under certain conditions wall-deficient or 'L-form' bacteria can be isolated. In Bacillus subtilis this normally requires two genetic changes. The first, exemplified by mutations shutting down wall precursor synthesis, works by...
متن کاملL-form bacteria, cell walls and the origins of life
The peptidoglycan wall is a defining feature of bacterial cells and was probably already present in their last common ancestor. L-forms are bacterial variants that lack a cell wall and divide by a variety of processes involving membrane blebbing, tubulation, vesiculation and fission. Their unusual mode of proliferation provides a model for primitive cells and is reminiscent of recently develope...
