Modularity and determinants of a (bi-)polarization control system from free-living and obligate intracellular bacteria

Although free-living and obligate intracellular bacteria are both polarized it is unclear whether the underlying polarization mechanisms and effector proteins are conserved. Here we dissect at the cytological, functional and structural level a conserved po ...

Sensing Gram-negative bacteria: a phylogenetic perspective

Bruno Lemaitre

Gram-negative bacteria represent a major group of pathogens that infect all eukaryotes from plants to mammals. Gram-negative microbe-associated molecular patterns include lipopolysaccharides and peptidoglycans, major immunostimulatory determinants across p ...

Environmental impact assessment of lignocellulosic lactic acid production: Integrated with existing sugar mills

Pavel Vaskan

Lactic acid (LA) is considered for the diversification and value addition to sugar industry in South Africa, through a bioconversion of sugarcane bagasse and leaves. A bioconversion process was modeled in Aspen Plus (R) V8.6 and its environmental impacts w ...

Kinetics of Antibody Binding to Membranes of Living Bacteria Measured by a Photonic Crystal-Based Biosensor

Giovanni Dietler, Ekaterina Rostova, Carine Ben Adiba

Optical biosensors based on photonic crystal surface waves (PC SWs) offer a possibility to study binding interactions with living cells, overcoming the limitation of rather small evanescent field penetration depth into a sample medium that is characteristi ...

Localization of adhesins on the surface of a pathogenic bacterial envelope through atomic force microscopy

Sandor Kasas, Giovanni Longo, Petar Stupar

Bacterial adhesion is the first and a significant step in establishing infection. This adhesion normally occurs in the presence of flow of fluids. Therefore, bacterial adhesins must be able to provide high strength interactions with their target surface in ...

Structure of viral membrane-penetrating machines by electron cryo-microscopy and tomography

Sergey Nazarov

My PhD thesis aims to obtain the structure of several bacteriophages, including so-called “jumbo” phages, using the electron cryo-microscopy (cryo-EM) and to study the structural transformation of these viruses as they attach and infect the host cell. We a ...

2-Carboxyquinoxalines Kill Mycobacterium tuberculosis through Noncovalent Inhibition of DprE1

Stewart Cole, Neeraj Dhar, Florence Pojer, Ruben Hartkoorn, Gaëlle Séraphine Kolly, Joao Pedro De Almeida Neres

Phenotypic screening of a quinoxaline library against replicating Mycobacterium tuberculosis led to the identification of lead compound Ty38c (3-((4-methoxybenzyl)amino)-6-(trifluoromethyl)quinoxaline-2-carboxylic acid). With an MIC99 and MBC of 3.1 mu M, ...

The mechanical world of bacteria

Alexandre Louis André Persat

In the wild, bacteria are predominantly associated with surfaces as opposed to existing as free-swimming, isolated organisms. They are thus subject to surface-specific mechanics, including hydrodynamic forces, adhesive forces, the rheology of their surroun ...

A novel crude glycerol assisted surfactant pretreatment strategy of chili post-harvest residue for bioethanol production

Edgard Gnansounou, Binod Parameswaran

A novel crude glycerol assisted surfactant pretreatment was evaluated for bioethanol production from chili post-harvest residue. Among the various surfactants screened crude glycerol assisted polyethylene glycol (PEG) pretreatment was found to be more effe ...

Listeria phage A511, a model for the contractile tail machineries of SPO1-related bacteriophages

Petr Leiman

Recognition of the bacterial host and attachment to its surface are two critical steps in phage infection. Here we report the identification of Gp108 as the host receptor-binding protein of the broad host-range, virulent Listeria phage A511. The ligands fo ...
