Microbial Dynamics at Biointerfaces: Controlling the Fate of Microbes under Spatial and Interfacial Confinements

Special seminar
Microbes self-organize in microcolonies at solid surfaces while transitioning to a sessile form within a protective biofilm matrix. Microbes also have complex community dynamics at fluid interfaces. While the biological implications of surface-attached and interfacial biofilms for the environment, health, and industry are widely appreciated, the earlier developmental stage of microbes as microcolonies has received scant attention. This presentation elucidates two new approaches to investigate microbial dynamics in spatially and interfacially confined microsystems. First, a new approach to studying microcolony formation and community dynamics is described. Using microfluidics-enabled fabrication, a nanoliter-scale sessile culture system (the nanoculture) is designed to grow synthetic microbial communities. Each nanoculture begins as a several nanoliter droplet of suspended cells, encapsulated by a polydimethylsiloxane (PDMS) membrane. The physicochemical properties of the encapsulation materials allow the diffusion of functional probes to interrogate cell physiology under chemical insults, allowing microbial interactions to be probed within or across the confining vessel. We use this versatile platform to investigate bacterial-fungal (inter-kingdom) dynamics that play a central role in early childhood dental caries and many infections. Second, microbial response to confinement at fluid-fluid interfaces are studied both in terms of physico-chemical effects and metabolic implications. We study two strains of P. aeruginosa, PAO1 and PA14. The PAO1 cells remodel the hexadecane-water interface to form highly elastic Films of Bacteria at Interfaces (FBI), i.e. elastic, solid films of bacteria and excreted polysaccharides, whereas the PA14 cells form active FBI that feature interface-associated microbes that remain highly motile. Transcriptional profiles of the interfacially confined strains suggest that the elastic FBI provides protection, in a manner akin to biofilms, enabling cells to cope with the detrimental effects of the interfacial environment. Together, these studies provide a basis for new strategies to minimize the deleterious impacts and to optimize the beneficial effects of microbial communities relevant to the environment and health. The nanoculture system and FBI-encapsulated droplets can also be exploited in upstream bioprocessing technologies, with uses ranging from the encapsulation of beneficial microbial communities to high-throughput screening of bioactive molecules.

Seeking intersections of microbiology, fluid mechanics, and physical chemistry

Special seminar
In this talk I describe various problems involving the intersections of fluid mechanics, bacterial biofilms and physical chemistry. I first highlight our studies of the influence of fluid motion on surface-attached bacteria and biofilms, where we identify and characterize upstream migration of surface-attached bacteria in a flow. Second, I highlight the influence of flow on quorum sensing, which refers to bacterial communication and collective behavior regulated by secreted chemicals. Our results suggest that bacterial colonization and biofilm development under flow can lead to heterogeneous QS activation, which promotes diversity in the genetic programs that bacteria enact. As a consequence, genetically identical bacteria exhibit different behaviours at particular regions and at particular times under flow. Finally, I describe an out-of-equilibrium consequence of concentration gradients, which, perhaps surprisingly, allow movement of particles (e.g. vesicles, DNA) in simple geometries. In particular, with salt gradients, via a mechanism referred to as diffusiophoresis, we can remove particles from dead-end pores or deliver particles into such pores. We explore the phenomenon using experiments and modeling. We close by posing the question if there might be broader consequences of these out-of-equilibrium physical chemistry ideas in biological contexts. [mehr]

Microbial symbionts of leaf-cutting ants (Atta and Acromyrmex)

Microbiology Seminar Series
Leaf-cutting ants harvest substantial amounts of leaf material to cultivate a specialized fungus for food (Leucoagaricus). This complex symbiosis includes at least four coevolved organisms: the farming ants, their fungal crop, a specialized mycoparasite of the ant’s fungal gardens (Escovopsis), and actinomycete bacteria (Pseudonocardia) that the ants culture on their bodies to obtain antibiotics against the parasites. We described an additional symbiosis with Nitrogen-fixing bacteria that colonize the fungus gardens and contribute to supplement the ants’ nutrition. Our present research efforts in Costa Rica focus on potential biotechnological applications of the ants’ microbial symbionts, including bioprospecting for new antibiotics and developing microbial-based biocontrol strategies.

Drivers of assembly and coexistence in communities of arbuscular mycorrhizal fungi - the scale matters!

Microbiology Seminar Series: SFB Mini Symposium
Arbuscular mycorrhizal (AM) fungi are asexual, obligately symbiotic fungi with unique morphology and genomic structure, which occupy a dual niche, that is, the soil and the host root. Consequently, the direct adoption of models for community assembly developed for other organism groups is not evident. Based on recent studies using high throughput molecular methods and their findings, I will give an overview on the factors driving AM fungal community assembly at different scales. By synthesizing these findings, I will show how modern coexistence and assembly theory can be adapted to arbuscular mycorrhizal fungi and that hierarchical spatial structure of arbuscular mycorrhizal fungal communities should be explicitly taken into account in future studies. This conceptual framework developed for arbuscular mycorrhizal fungi is also adaptable for other host-associated microbial communities. [mehr]

Transmembrane chemoreceptors are central components in the sensory system that mediates bacterial chemotaxis. Like many transmembrane proteins, these receptors are fully active only if inserted in a lipid bilayer. This requirement presents a challenge for in vitro analysis by many biochemical and structural techniques. The challenge is met by Nanodiscs, soluble, nanoscale (~10 nm diameter) particles of lipid bilayer surrounded by an annulus of amphipathic protein into which transmembrane proteins can be incorporated. Using Nanodiscs, we documented that chemoreceptor dimers bend at a specific locus along their 300 Å long axis, discovered that conformational differences between chemoreceptor signalling states were differential propensities of receptor helices to become momentarily unstructured, and determined that chemoreceptor signalling complexes activate and control the chemotaxis histidine kinase by altering its catalytic rate constant.

Genomics-enabled natural product discovery

Natural products have been, without question, the most prolific source of all medicines, especially antibiotics. Genome sequencing has revealed that our knowledge of natural product structure and function is astonishingly incomplete. Therefore, exploration of uncharted natural product chemical space will undoubtedly lead to improved, and entirely new, medicines. Against this backdrop, our group focuses on elucidating the biosynthesis, structure, and function of natural products. This talk will highlight our recent advances in genomics-enabled natural product discovery while covering a few case studies in enzymatic biosynthesis that could be exploited to introduce new drug leads.

Oxymonads – eukaryotes without mitochondrion

Mitochondrion is a key evolutionary inventions specific to the eukaryotic cell. Oxymonads remained as one of a few eukaryotic groups, where no mitochondrion has been revealed so far. We have performed detailed genomic and transcriptomic study of oxymonad Monocercomonoides sp., which demonstrates the absence of mitochondrial hallmark proteins. The most striking is the absence of canonical mitochondrial protein import machinery and the substitution of mitochondrial iron sulphur cluster biosynthetic pathway (ISC) by the sulphur mobilization system (SUF). We conclude that Monocercomonoides represents the first report of amitochondriate eukaryote demonstrating the fact that under some circumstances eukaryotes may entirely loose mitochondrion. [mehr]

From ancient lipids to synthetic life

The function of the cell membrane as a barrier and a matrix for biochemical activity relies on the properties imparted by lipids. In eukaryotes, sterols are crucial for modulating the molecular order of membranes. Sterol ordering provides the basis for membrane lateral segregation and promotes a fluid, mechanically robust plasma membrane. How do organisms that lack sterols determine membrane order? Hopanoids are ancient bacterial membrane lipids that have been proposed as putative sterol surrogates. We now explore the role of hopanoids, their effect on membranes in Methylobacterium extorquens and reflect on the path to building functional synthetic membranes. [mehr]

Modeling chemotactic pattern formation in E. coli bacteria

Linking metabolic and cell cycle regulation

The cell division cycle consists of a sequence of processes whose specific demands for biosynthetic precursors and energy place dynamic requirements on metabolism. However, little is known about how metabolic fluxes are coordinated with the cell cycle. I will present our recent findings that over half of all measured metabolites change significantly through the cell division cycle. We find that the cyclin-dependent kinase Cdk1, a major cell cycle regulator, also controls carbon metabolism. Trehalose utilization fuels anabolic processes required to reliably complete cell division. This demonstrates how cell cycle regulation can entrain carbon metabolism to dynamically fuel biosynthesis during proliferation. [mehr]

Bacterial shapeshifting: Escherichia coli differentiation during urinary tract infection

Urinary tract infections are caused primarily by uropathogenic strains of Escherichia coli (UPEC). UPEC is known to transition through a series of distinct infection stages, displaying reversible morphological differentiation along the way. Initial steps involve bladder invasion by rod-shaped bacteria to establish intracellular bacterial communities consisting of coccoid cells. Subsequently, during exit from infected cells, UPEC regain their rod-shape and in some cases even form large filaments. Using a flow-chamber based tissue culture infection model we have studied UPEC gene expression during the course of infection. Our results reveal a novel SOS-independent mechanism of reversible cell-division control. [mehr]
