Antimicrobial, antioxidant, and antitumor activity of epsilon-poly-L-lysine and citral, alone or in combination
BACKGROUND Food safety is an important worldwide public health concern, and microbial contamination in foods not only leads to food deterioration and shelf life reduction but also results in economic losses and disease. OBJECTIVE The main aim of the present study was to evaluate the effect of epsilon-poly-L-lysine (ε-PL) and citral combination against Escherichia coli O157:H7 (E. coli O157:H7...
متن کاملLauryl-poly-L-lysine: A New Antimicrobial Agent?
The development of multiple antibiotic resistance is a global problem. It is necessary to find new tools whose mechanisms of action differ from those of currently used antibiotics. It is known that fatty acids and cationic polypeptides are able to fight bacteria. Here, we describe the synthesis of fatty acids linked to a polypeptide with antibacterial activity. The linkage of fatty acids to a p...
متن کاملGenome Sequence of Streptomyces albulus PD-1, a Productive Strain for Epsilon-Poly-l-Lysine and Poly-l-Diaminopropionic Acid
Streptomyces albulus PD-1, a productive strain for epsilon-poly-l-lysine and poly-l-diaminopropionic acid, was isolated from soils. We present the genome sequence of S. albulus PD-1, which may provide abundant information regarding the production of epsilon-poly-l-lysine and poly-l-diaminopropionic acid.
متن کاملInhibition of epsilon-poly-L-lysine biosynthesis in Streptomycetaceae bacteria by short-chain polyols.
Antimicrobial epsilon-poly-L-lysine (ePL) is secreted by Streptomycetaceae bacteria, and the mechanism of ePL biosynthesis remains to be elucidated. We previously reported that an unknown ePL derivative accumulates in the culture medium of ePL-producing bacteria when glycerol is added to the culture medium (Nishikawa and Ogawa, Appl. Environ. Microbiol. 68:3575-3581, 2002). In this study, by us...
متن کاملEpsilon-poly-L-lysine dispersity is controlled by a highly unusual nonribosomal peptide synthetase.
Epsilon-Poly-L-lysine (epsilon-PL) consists of 25-35 L-lysine residues in isopeptide linkages and is one of only two amino acid homopolymers known in nature. Elucidating the biosynthetic mechanism of epsilon-PL should open new avenues for creating novel classes of biopolymers. Here we report the purification of an epsilon-PL synthetase (Pls; 130 kDa) and the cloning of its gene from an epsilon-...
