A chromatographic approach to distinguish Gram-positive from Gram-negative bacteria using exogenous volatile organic compound metabolites [PDF]
, 2017 This paper utilized L-alanine aminopeptidase activity as a useful approach to distinguish between Gram-negative and Gram-positive bacteria. This was done using two enzyme substrates, specifically 2-amino-N-phenylpropanamide and 2-amino-N-(4-methylphenyl ...

LL‐37 Driven Phase Transition and Stacking in Oligolamellar Gram‐Negative Bacterial Membrane Models
Advanced Functional Materials, EarlyView.This work establishes oligolamellar bacterial membrane models to investigate how LL‐37 disrupts the complex dual‐bilayer architecture of Gram‐negative bacteria. Combining SAXS, cryo‐TEM, electrophoretic mobility measurements, and coarse‐grained simulations, it reveals cardiolipin‐driven phase transitions leading to bicelle‐like structures and membrane ...

Production, reproduction, and reversion of protoplast-like structures in the osmotic strain of Neurospora crassa [PDF]
, 1958 Protoplasts devoid of cell walls have been produced in Bacillus megaterium and certain other Gram-positive species of bacteria.(1) Structures resembling protoplasts but not completely devoid of cell walls have also been produced in Escherichia coli and ...

Human platelet activation by Escherichia coli: roles for FcγRIIA and integrin αIIbβ3 [PDF]
, 2016 Gram-negative Escherichia coli cause diseases such as sepsis and hemolytic uremic syndrome in which thrombotic disorders can be found. Direct platelet–bacterium interactions might contribute to some of these conditions; however, mechanisms of human ...

Biocompatible but Antibacterial Mechanism of Graphene Oxide for Sustainable Antibiotics
Advanced Functional Materials, EarlyView.Graphene oxide (GO) exhibits selective antibacterial activity through specific interactions between its oxygen functional groups and bacterial membrane phospholipid POPG, causing membrane destabilization while maintaining biocompatibility. Model membrane studies and infected wound models in mice and pigs demonstrate effective bacterial suppression and ...

Protamine-like proteins have bactericidal activity. The first evidence in Mytilus galloprovincialis. [PDF]
, 2018 The major acid-soluble protein components of the mussel Mytilus galloprovincialis sperm chromatin consist of the protamine-like proteins PL-II, PL-III and PL-IV, an intermediate group of sperm nuclear basic proteins between histones and protamines.
