Iron phosphate mediated magnetite synthesis: a bioinspired approach

Giulia Mirabello

The biomineralization of intracellular magnetite in magnetotactic bacteria (MTB) is an area of active investigation. Previous work has provided evidence that magnetite biomineralization begins with the formation of an amorphous phosphate-rich ferric hydrox ...

Dissimilarities in polyphosphate accumulation between Shewanella loihica and the model bacterium Shewanella oneidensis

Julien Maillard

Polyphosphate plays an important role in the physiological adaptation of bacteria during growth and development, as well as in their response to nutritional and environmental stresses. Moreover, polyphosphate accumulation is of environmental relevance and ...

Cellular advective-diffusion drives the emergence of bacterial surface colonization patterns and heterogeneity

Alexandre Louis André Persat, Tamara Rossy

Microorganisms navigate and divide on surfaces to form multicellular structures called biofilms, the most widespread survival strategy found in the bacterial world. One common assumption is that cellular components guide the spatial architecture and arrang ...

Maturing Mycobacterium smegmatis peptidoglycan requires non-canonical crosslinks to maintain shape

Georg Fantner, John McKinney, Haig Alexander Eskandarian

In most well-studied rod-shaped bacteria, peptidoglycan is primarily crosslinked by penicillin-binding proteins (PBPs). However, in mycobacteria, crosslinks formed by L,D-transpeptidases (LDTs) are highly abundant. To elucidate the role of these unusual cr ...

Bacteria inactivation during the drying of struvite fertilizers produced from stored urine

Tamar Kohn, Loïc Decrey, Simon Schindelholz, Manfred Schoger, Kai Udert

Human urine can be processed into market-attractive fertilizers like struvite; however, concerns regarding the microbial safety of such products remain. The present study evaluated the inactivation of in situ heterotrophs, total bacteria as observed by flo ...

Cell Division by Longitudinal Scission in the Insect Endosymbiont

Bruno Lemaitre, Graham Knott, Catherine Maclachlan, Elodie Julie Virginie Ramond

Spiroplasma bacteria are highly motile bacteria with no cell wall and a helical morphology. This clade includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster. S. poulson ...

The regulatory isoform rPGRP-LC induces immune resolution via endosomal degradation of receptors

Bruno Lemaitre, Fanny Schüpfer

The innate immune system needs to distinguish between harmful and innocuous stimuli to adapt its activation to the level of threat. How Drosophila mounts differential immune responses to dead and live Gram-negative bacteria using the single peptidoglycan r ...

On the bioavailability of trace metals in surface sediments: a combined geochemical and biological approach

The bioavailability of metals was estimated in three river sediments (Sens,e, Scarpe, and DeA >> le Rivers) impacted by different levels of Cu, Cd, Pb, and Zn (Northern France). For that, a combination of geochemistry and biological responses (bacteria and ...

Electrical resistance of single-crystal magnetite (Fe3O4) under quasi-hydrostatic pressures up to 100GPa

Helmuth Berger

The pressure dependence of electrical resistance of single-crystal magnetite (Fe3O4) was measured under quasi-hydrostatic conditions to 100 GPa using low-temperature, megabar diamond-anvil cell techniques in order to gain insight into the anomalous behavio ...
