Cody E. Garrison, Kyra A. Price, Erin K. Field. 2019. Environmental Evidence for and Genomic Insight into the Preference of Iron-Oxidizing Bacteria for More-Corrosion-Resistant Stainless Steel at Higher Salinities. Applied and Environmental Microbiology. 85(14) e00483-19; DOI: 10.1128/AEM.00483-19

Cover Photo: Scanning electron microscope image of a novel species of iron-oxidizing bacteria, Mariprofundus erugo, isolated from stainless steel deployed in a North Carolina estuarine river. Iron-oxidizing bacteria are one of the initial colonizing microorganisms during biocorrosion of steel, and this new species may be adapted to more-advanced anthropogenic iron sources such as stainless steel. Growth is characterized by helical stalk iron oxide morphologies as seen here.

Al-Hinai, M.A., Jones, S.W., Papoutsakis, E.T. 2015. The Clostridium sporulation programs: diversity and preservation of endospore differentiation. Microbiol Mol Biol Rev doi:10.1128/MMBR.00025-14.

Cover Photo: Transmission electron micrographs (TEMs) of Clostridium acetobutylicum at different stages of its developmental (sporulation) program, from a symmetrically dividing vegetative cell on the left to a maturing spore on the right. Pseudocolor is used to accentuate key features of the various cellular forms, notably those of granulose vesicles (light green), the developing endospore (light blue), the spore membrane (dark yellow), and the spore cortex (brown), which is surrounded by the thin “black” spore coat. The phenotypic characteristics of the sporulation program of Clostridium organisms are similar to that of Bacillus spp., with the key exception that Clostridium organisms synthesize the storage material granulose (made of amylopectin). Granulose is packed in vesicles, whose accumulation leads to swelling of the cell, giving rise to the cigar-shaped clostridial cell form that looks like a spindle. The genus name “Clostridium” (as well as the class name “Clostridia”) derives from the Greek word for spindle, klōstēr. Despite the similar phenotypic characteristics, the molecular orchestrations of sporulation are quite distinct between Clostridium and Bacillus. TEM images are not to scale and were arranged for artistic impact. TEM images are from the collection of the Papoutsakis lab at the University of Delaware and were obtained at the Delaware Biotechnology Institute BioImaging Center. The cover composition was conceived by E. Terry Papoutsakis and executed by Patrick Lane of ScEYEnce Studios.

Cover Photo: The 3D-rendered image shows tubular projections called stromules from multiple chloroplasts (blue) surrounding a nucleus (yellow) during a plant immune response, observed by confocal laser scanning microscopy. Chloroplasts (magenta) in the mesophyll cells are in the background. Defense signaling molecules and proteins from chloroplasts may be transported to the nucleus via such stromules.

Cover Photo: Immunolocalization of JAM-A (red) and integrin α_IIbβ₃ (blue) on human platelet exposed to immobilized fibrinogen. Platelets were also stained with phalloidin to visualize F-actin (green). The image is a 3D rendering of a super-resolution structured illumination microscopy (SIM) dataset.

Cover Photo: Biomechanical and notably shear forces are essential for megakaryocytic maturation and platelet biogenesis, but also for generating megakaryocytic microparticles, which are capable of programming hematopoietic stem and progenitor cells to differentiate into megakaryocytes. This immunofluorescent image shows a partially disintegrated human polyploid megakaryocyte giving rise to various megakaryocytic particles through β1 tubulin (green) extensions. F-actin is shown in red and the nuclear structures are shown in blue (TO-PRO-3).

Implantable three-dimensional salivary spheroid assemblies demonstrate fluid and protein secretory responses to neurotransmitters. Tissue Engineering Part A. 19 (13-14): DOI: 10.1089/ten.tea.2012.0301

Cover Photo: Three-dimensional surface reconstruction of primary human salivary acinar-derived cells in hyaluronic acid-based hydrogels. Individual cells form aggregate clusters, which gradually expand, develop a lumen, and respond to neurotransmitters. Cells in the image were stained with live/dead (green/red) staining and blue nuclei, and imaged by confocal microscopy. The resulting z-stack was reconstructed in Amira software.

Cover Photo: Laser scanning confocal microscopic image of fluorescently labeled hen egg lysozyme in cation exchange particles. The bright red rings indicate areas of higher protein concentration and occur only after initial protein uptake. These findings demonstrate that mechanisms other than diffusion contribute to protein transport in oppositely charged porous material.
