The effect of organic carbon and nitrogen additions on inorganic nitrogen uptake by phytoplankton and bacteria
… was observed by both the phytoplanktonic and bacterial fractions, with RPINH4 values typically between 1 and 5. The bacterial fraction ( <0.8μm) was found to be responsible for as much as 48-75% of community uptake of ammonium; while the netplanktonic fraction was observed to take up …

Experimental Investigation on Microplastics Biofouling Rate in an Aquatic System
… Ontario conditions, were conducted to analyze bacterial growth and biofilm formation on different microplastic sizes. The study investigated factors such as bacteria type, nutrient availability, shaking speed, microplastic size, and flow rate on MP biofouling formation and growth. This study …

Characterizing the advantages of diverse effector secretion in Pseudomonas aeruginosa
… bacteria exist in complex communities with other bacterial species, where they compete for resources. Cells are frequently in close proximity to one another, and therefore, many bacteria have evolved pathways to intoxicate their neighbors directly. One such pathway is the type VI secretion system …

Streptococcus equi subsp. zooepidemicus in New Zealand horses
… reduce to just the infective strain, indicating bacterial competition and strain fitness advantages. Factors available to S. zooepidemicus to colonise and persist in the horse include biofilm formation and cellular invasion with the majority of strains tested in vitro, able to form biofilms and …

The role of the Vibrio cholerae Type VI secretion system during kin cell interaction, biofilm formation and priority effects
… the closer we get to understanding its role in bacterial competition; inter-and-intra, and how this shapes a bacterial niche. Further, although the probiotic-like effect in the <em>V. cholerae </em>vaccine is described to work fast due to niche uptake hindering colonization of toxigenic strains, …

The Role of Mechanics on Microbial Ecology within Confined Spaces
Spatial competition is strongly driven by mechanical interactions when microbial colonies inhabit a confined and packed environment, which is crucial to the stability and diversity of the entire ecological system. However, much of the dynamics is lost in conventional bulk measurements without …

Characterizing the Role of the Type VI Secretion System in Interbacterial Species Interactions and Pathogenesis
… needle complex that spans across the entire bacterial cell wall and functions through a contraction mechanism that results in the delivery of toxic effector proteins into neighbouring cells. Virulence is achieved through the targeting of essential components found in either eukaryotic or …
