Factors affecting the competitiveness of bacterial fermentation
Trends in Biotechnology, 2023Sustainable production of chemicals and materials from renewable non-food biomass using biorefineries has become increasingly important in an effort toward the vision of 'net zero carbon' that has recently been pledged by countries around the world. Systems metabolic engineering has allowed the efficient development of microbial strains overproducing ...

Deadly competition between sibling bacterial colonies [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2009 Bacteria can secrete a wide array of antibacterial compounds when competing with other bacteria for the same resources. Some of these compounds, such as bacteriocins, can affect bacteria of similar or closely related strains. In some cases, these secretions have been found to kill sibling cells that belong to the same colony. Here,

Competition sensing: the social side of bacterial stress responses
Nature Reviews Microbiology, 2013 The field of ecology has long recognized two types of competition: exploitative competition, which occurs indirectly through resource consumption, and interference competition, whereby one individual directly harms another. Here, we argue that these two forms of competition have played a dominant role in the evolution of bacterial regulatory networks ...

Bacterial competition: surviving and thriving in the microbial jungle [PDF]
Nature Reviews Microbiology, 2009 Most natural environments harbour a stunningly diverse collection of microbial species. In these communities, bacteria compete with their neighbours for space and resources. Laboratory experiments with pure and mixed cultures have revealed many active mechanisms by which bacteria can impair or kill other microorganisms.

Bacterial Competition in the Presence of a Virus in a Chemostat
Mathematics, 2023 We derive a mathematical model that describes the competition of two populations in a chemostat in the presence of a virus. We suppose that only one population is affected by the virus. We also suppose that the substrate is continuously added to the bioreactor.

Bacterial coexistence driven by motility and spatial competition
Nature, 2020Elucidating elementary mechanisms that underlie bacterial diversity is central to ecology1,2 and microbiome research3. Bacteria are known to coexist by metabolic specialization4, cooperation5 and cyclic warfare6-8. Many species are also motile9, which is studied in terms of mechanism10,11, benefit12,13, strategy14,15, evolution16,17 and ecology18,19 ...

Bacterial competition: How to hotwire a flagellum
Current BiologyTranslocation of an effector from one soil microbe into a competitor forces the recipient to swim away using a mechanism that bypasses canonical cyclic di-GMP repression of flagellar gene biosynthesis.

Bacterial competition in serial transfer culture
Mathematical Biosciences, 2011A mathematical model of bacterial competition for a single growth-limiting substrate in serial transfer culture is formulated. Each bacterial strain is characterized by a growth response function, e.g. Monod function determined by a maximum growth rate and half-saturation nutrient concentration, and the length of its lag phase following the dilution ...

A simple biofilm model of bacterial competition for attached surface
Water Research, 2002A simple biofilm model of competition in bacterial growth for an attached surface is developed. Competition for the attached surface is expressed with the crowded and detachment effects. The developed model is verified by comparing simulated results with data obtained in the experiments of batch culture of nitrifier and continuous treatment of actual ...

Effect of bacterial chemotaxis on dynamics of microbial competition
Microbial Ecology, 1988Although the dynamic behavior of microbial populations in nonmixed systems is a central aspect of many problems in biochemical engineering and microbiology, the factors that govern this behavior are not well understood. In particular, the effects of bacterial chemotaxis (biased migration of cells in the direction of chemical concentration gradients ...
