ε-Poly- l -lysine: microbial production, biodegradation and application potential
Toyokazu Yoshida,Toru Nagasawa +1 more
TL;DR: The mechanism of the inhibitory effect of ε-PL on microbial growth is the electrostatic adsorption to the cell surface of microorganisms on the basis of its poly-cationic property.

Recent Developments on Biobased Curing Agents: A Review of Their Preparation and Use
Cheng Ding,Avtar S. Matharu +1 more
TL;DR: In this paper, a review of recent advances in the development of biobased curing agents from renewable materials is presented. But the focus is on epoxy resins and their applications in various fields, such as coatings, adhesives, castings, modeling compounds, impregnation materials, high performance composites, insulating materials, and encapsulating and packaging materials for electronic devices.
Journal ArticleDOI
Microbial degradation of poly(amino acid)s.
TL;DR: The focus is on the naturally occurring poly(amino acid)s cyanophycin, poly(epsilon-L-lysine) and poly(gamma-glutamic acid); but biodegradation of structurally related synthetic polyamides such as poly(aspartic acid) and nylons, which are known from various technical applications, is also included.

Antimicrobial action of epsilon-poly-L-lysine.
TL;DR: Investigation of the antimicrobial spectrum of epsilon-poly-L-lysine found it to be optimum for antimicrobial activity, and studies on the mode of action suggest that absorption of ePSilon-PL to the bacterial cell surface plays an important role in its antibacterial activity.
Journal ArticleDOI
Polylysine Produced by Streptomyces
Shoji Shima,Heiichi Sakai +1 more
TL;DR: In the course of the screening for Dragendorff positive substance from microbial origin, polylysine (lysinepolymer) from culture filtrate of a streptomycete is found, a unique observation not hitherto described.

Hilton B. Levy,George M. Baer,Samuel Baron,Charles E. Buckler,C. J. Gibbs,M. J. Iadarola,W. T. London,Jerry Rice +7 more
TL;DR: A comlex of polyriboinosinic-polyribocytidylic acid with poly-L-lysine and carboxymethylcellulose with significant levels of serum interferon in monkeys and chimpanzees under conditions in which poly I-poly C itself induces no interferons is prepared.
Journal ArticleDOI
Conjugation of methotrexate to poly(L-lysine) increases drug transport and overcomes drug resistance in cultured cells
TL;DR: It is shown that in methotrexate-resistant cells the intracellular release of active drug after uptake of conjugate is of the same order of magnitude as the uptake of free drug by transport-proficient cells and, hence, that the drug resistance due to deficient transport can be totally overcome.
Journal ArticleDOI
Colorimetric method for estimating polylysine and polyarginine
TL;DR: A rapid and sensitive method is described for estimating polylysine and polyarginine by the stoichiometric precipitation of these polyamino acids by excess of the anionic dye methyl orange, followed by spectrophotometric determination of unbound dye.
