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

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

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. [more]

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

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!

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. [more]

Structural features and signalling mechanisms of transmembrane chemoreceptors identified utilizing Nanodiscs

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.
