Bacterial Interspecies Interactions and Microbial Community Assembly
… droplets show a wide occurrence of bacterial interactions in the form of one species or consortium affecting the abundance and yield of another species. Positive and negative interactions appear unavoidable in bacterial co-cultures when growth is permitted, with growing bacteria typically …

Insights into microbial community structure from pairwise interaction networks
… a bottom-up approach to investigate the role of interspecies interactions in determining the structure of multispecies communities. First, we investigate the network of pairwise competitive interactions in a model community consisting of 20 strains of naturally co-occurring soil bacteria. The …

Functional genomics analysis of carbohydrate conversion to biohydrogen by pure and mixed cultures of hyperthermophilic Thermotoga species.
… response analysis provided clues to interspecies interactions. In glucose mixed culture, the ORFs encoding a phage tail-like bacteriocin (TM0785), lon proteases (TM1633, TM1869), ï ³E (TM1598), and a putative bacteriocin (TM1300) related to subtilosin A from Bacillus subtilis, were …

Changes in archaeal and bacterial community composition following entombment in halite crystals
… time. This is presumably due to a complex web of interspecies interactions, co-operations and the sharing of usable metabolites. Nevertheless, some organisms are poor survivors inside halite and showed a decrease in their relative abundance in halite. In this study, this was highlighted by the …

In vitro Recapitulation of the Polymicrobial Communities Associated with Cystic Fibrosis Airway Infections
… combination of bacteria and fungi. The role of interspecies interactions in modulating changes in gene expression and the metabolism of individual members of a polymicrobial community, compared with growth as an axenic population, is becoming increasingly apparent within the field of medical …

Emergent behaviors in complex microbial ecosystems
… that as the number of species or the strength of interactions increases, microbial ecosystems transition through three distinct dynamical phases: from stable coexistence, to partial coexistence, to the emergence of persistent fluctuations and alternative stable states in species abundances, …

Impacts of mucins on microbial physiology and interactions
… to determine the influence of these molecules on interspecies interactions. Whereas P. aeruginosa typically kills C. albicans, mucins protect the fungus from bacterial pathogenicity. Therefore, in addition to influencing microbial virulence, mucins can impact microbial community dynamics. Overall, …

Bridging prairie restoration and regenerative agriculture with compost tea / the rocket incident: post-fire soil microbe recovery on the Eastern Washington University restoration site
… for restoration of the plant community through interspecies interactions within the rhizosphere. One method for improving soil microorganism community composition is compost tea: enriched liquid compost extract. Compost tea is used in regenerative agriculture to improve crop yields and protect …

Characterizing the Role of the Type VI Secretion System in Interbacterial Species Interactions and Pathogenesis
… of environmental signals and their influence on interspecies interactions and the expression of the T6SS, remain largely unknown. Here, I examined the role of the T6SS in the context of multispecies communities. Using a mix of two antagonistic T6SS strains, Vibrio cholerae V52 and Aeromonas …

Nesting aggregation as a Determinant of Brood Parasitism in Mason Bees (Osmia spp.)
Identifying forces that affect population dynamics can allow us to better understand the distribution and abundance of animals. Both top-down and bottom-up factors can significantly influence animal populations. Mason bees (members of the genus Osmia; Hymenoptera: Megachilidae) are important …

Particle tracking for understanding the properties and dynamics of bacterial biofilms
… The second can allow for further assessment of interspecies interactions, perhaps to probe the specific mechanisms by which bacteria can attach to one another to improve motility.

Bifidobacterial interactions with human milk oligosaccharides and their combined potential for the advancement of infant nutrition
… microbiome, and what mechanisms underlie these interactions? The specific objectives included: Acquisition of a comprehensive understanding of the functional biology of HMOs, detailing their importance in infant development and gut health (Chapter I), gain insights into the characterization, …
