|Cooperative bacterial strains colonizing a surface|
In a new study published this month, we examined the role of cooperation in shaping spatial patterns of bacterial organization on wet surfaces. The paper is available online and is entitled 'Cooperation in carbon source degradation shapes spatial self-organization of microbial consortia on hydrated surfaces'. Our idea was that a feeding dependency between two partners would directly control their distribution in space, hence imposing a specific pattern. We used a simple model system made of two bacterial strains that could grow using the chemical compound toluene (a hydrocarbon), but only when they were working together as a 'team' (a bacterial consortium in the jargon).
