Antimicrobial peptides represent an alternative to traditional antibiotics that may be less susceptible to bacterial resistance mechanisms by directly attacking the bacterial cell membrane. However, bacteria have a variety of defense mechanisms that can prevent cationic antimicrobial peptides from reaching the cell membrane. The L- and D-enantiomers of the antimicrobial peptide GL13K were teste...
BACKGROUND The targeting of Staphylococcus aureus biofilm structures are now gaining interest as an alternative strategy for developing new types of antimicrobial agents. Magnolol (MOL) shows inhibitory activity against S. aureus biofilms and Triton X-100-induced autolysis in vitro, although there are no data regarding the molecular mechanisms of MOL action in bacteria. METHODOLOGY/PRINCIPAL ...
The objective of this study was to determine whether differences in pork tenderness and water-holding capacity could be explained by factors influencing calpain activity and proteolysis. Halothane-negative (HAL-1843 normal) Duroc pigs (n = 16) were slaughtered, and temperature and pH of the longissimus dorsi (LD), semimembranosus (SM), and psoas major (PM) were measured at 30 and 45 min and 1, ...
Autolysis of Bacillus cereus N.R.R.L. 569 cell walls was accompanied by hydrolysis of the majority of the 4-O-beta-N-acetylglucosaminyl-N-acetylmuramic acid linkages in mucopeptide, presumably by an endo-beta-N-acetylglucosaminidase. Hydrolysis of the N-acetylmuramyl-l-alanine linkages by an amidase also occurred. Free d-alanine residues were detected in isolated cell walls and the proportion o...
Information is lacking on preserving fish carcasses to minimize postmortem autolysis artifacts when a necropsy cannot be performed immediately. The purpose of this study was to qualitatively identify and score histologic postmortem changes in two species of freshwater fish (bluegill-Lepomis macrochirus; crappie-Pomoxis annularis), at varied time intervals and storage temperatures, to assess the...
Abstract The yeast autolysis process - an endogenous and irreversible lytic event, which occurs in cells caused by the action of intracellular enzymes, proteases carbohydrases is a well-known economic process, however, there constant risk serious microbial contamination since are many nutrients broth this slow, favoring growing pathogens. present work comes up with attempt to accelerate Sacchar...
Mercuric ions were the only metal ions which prevented autolysis of Neisseria gonorrhoeae, as measured both by stabilization of optical density and by prevention of release of [3H]diaminopimelic acid.
