Syntrophy, or cross-feeding, is the co-existence of two or more microbes whereby one feeds off the products of the other. Recently, we have developed an integrated multi-scale flux modeling approach that allows us, for the first time, to dissect interactions in microbial communities using 13C tracers. Specifically, to quantify metabolism and identify cross-feeding interactions we have developed a compartmental multi-scale 13C metabolic flux analysis (13C-comMFA) approach that quantifies metabolic fluxes for multiple cell populations in microbial communities without separation of cells or proteins. In this presentation, I will illustrate our investigations of metabolic interactions between E. coli auxotrophs that are unable to grow on glucose in minimal medium by themselves, but can grow on glucose when cultured together. Using our novel 13C-comMFA flux analysis tool we have quantified metabolic interactions (i.e. metabolite cross-feeding) in four distinct synthetic E. coli co-cultures. We also applied adaptive laboratory evolution to elucidate how syntrophic interactions evolve and are strengthened through adaptive co-evolution of co-cultures. Overall, the methods we have developed for studying microbial communities enable a broad new area of investigations, allowing us and others to dissect complex microbial systems that are of significant importance in biology but cannot be investigated with current tools. More broadly, by better understanding syntrophic relationships at the genetic, molecular, cellular and systems levels we are generating new knowledge on microbial syntrophy that enables us to ensemble synergistic interactions in engineered microbial communities for novel applications.

Research Scientist, Air Quality Research Division
Environment and Climate Change Canada (ECCC)
Abstract: Atmospheric carbonaceous aerosols can have significant impacts on both air quality and climate. However, impacts of atmospheric brown carbon (BrC), the light absorbing fraction of organic aerosols (OAs) that can heat up the atmosphere, on global and regional climate are subject to large uncertainties due to the lack of understanding on their sources, formation processes and atmospheric evolution. While biomass burning has been recognized as the major sources of atmospheric BrC in global scale, the contributions of other primary sources and secondary processes to atmospheric BrC remain less understood. The first part of this talk will focus on the field observations in Singapore, a well-developed coastal city in warm and humid tropical region, based on a novel combination of high resolution aerosol mass spectrometry and aethalometer measurements. The results provide evidence that local combustion emissions and fresh secondary OA (SOA) formed with industrial influence can be important sources of BrC in urban environments, and biomass burning-derived BrC observed during the haze episode in the Southeast Asian region are susceptible to significant degradation in light absorptivity during regional transport. The second part will present laboratory observations that shows the dynamic impacts of relative humidity on secondary BrC formation in aqueous-phase upon fast droplet evaporation that is relevant to atmospheric cloud processing. The potential effects of anthropogenic-biogenic interactions on secondary BrC formation via aqueous-phase processing will be also discussed.

Abstract: Most new polymeric products contain two or more polymers and/or functional additives resulting in desired properties contributed from each component. Recently, our group is focusing on creating hierarchically structured hybrid composites and coextruded micro-/nano-layered structures to tune the material properties. In this presentation, an approach will be presented to develop synergy-induced hierarchically structured Polypropylene (PP)-based hybrid composites, reinforced with Graphene Nanoplatelets (GnP) and Glass Fibers (GF), capable of achieving advanced properties and functionalities. These advanced multifunctional hybrid composites can be tailored for a variety of high-performance applications by exploiting the mechanisms governing the synergistic effect. In this hierarchical system, the GnPs (i.e., nano-sized filler) are chemically and electrostatically attached to the GFs (i.e., micro-sized filler), favoring load transfer at the interface, while simultaneously enhancing the crystalline microstructure of the PP matrix. Furthermore, the volume exclusion effect induced by the GFs, promotes the formation of GnP-based conductive networks. Strategically controlling the reinforcement concentrations has been proven to directly influence the magnitude of these mechanisms, effectively enhancing the synergistic effect, thereby allowing the mechanical, electrical, and thermal conductive properties of these advanced hybrid composites to be tailored based on their application.
Secondly, a fundamental and experimental investigation of cell nucleation and growth mechanisms in advanced Micro-/Nano-Layered (MNL) polymeric structures with alternating film and foam layers will be discussed. Foams can be prepared from any type of plastic by introducing a gas or supercritical fluid (SCF) within the polymer matrix. The applications of microcellular plastics containing billions of tiny bubbles less than 10 microns in size have broadened due to the lightweight characteristics, excellent strength-to-weight ratios, superior insulating abilities, energy absorbing performances, and the comfort features associated with plastic foams, as well as their cost-effectiveness and cost-to-performance ratios. We found that the cell nucleation and growth phenomenon in MNL systems are governed by the synergy of two categories of parameters: morphological parameters (i.e., film and foam layer thicknesses and the number of layer interfaces) and material parameters (i.e., material stiffness and compatibility with neighboring layers). The presence of adjacent film layers can significantly increase cell density through three mechanisms: promoting heterogeneous cell nucleation, preventing cell deterioration, and confining cell growth. The influence of film layers varied in different layer thickness regions and interface densities, where stiffer and more compatible film layers produced higher cell densities.

Abstract: Cellulose, as the most common bio-polymer in the world, is an important resource for replacing fossil-based plastics. Cellulose is not intrinsically thermoplastic and must be chemically modified to achieve melting behaviour, expected by the plastics processing industry. The cellulose modification methods known so far are resource- and energy-intensive. This stimulates development of more sustainable routes. Therefore, TalTech is devising and demonstrating novel, sustainable esterification routes for preparing thermoplastic fatty acid cellulose esters (FACEs). Sustainability is ensured by minimizing the impact of the esterification agents, dissolution environment and modification methods. The cellulose esterification processes are based on chemically modified plant oils, new protonic ionic liquids, catalytic effects and the mechanochemical effect of reactive extrusion (REX). Certain components of the ionic liquids, the organic superbases can catalyze the esterification reactions. Plant oils and especially their production residues are valuable source of sustainable, fully bio-based esterification reagents. Their reactivity is improved by certain chemical modifications as well as catalytic and mechanochemical effects. The process can accept several primary or secondary sources of cellulose as dissolving pulp or microcrystalline cellulose. The study is accompanied by life cycle assessment of both production and products, including recycling of solvents and by-products, environmental durability of biopolymer films and recyclability. Research in REX experiments with a recently installed laboratory scale pilot-line is directed by project PI Prof. Andres Krumme.
