Interactions of two nearby bacterial colonies - the effect of signaling molecules and nutrients on the colony growth
 Dobřemyslová, Mária ; Fišer, Radovan (advisor) ; Zikánová, Blanka (referee)
Between neighbouring bacterial colonies of the same species there occur mutual interactions influencing their growth (both size and pattern). Effects of these interactions on the growth can be both negative and positive, and can change in the course of development of colonies. The primary cause of mutual influence is often competion for available sources of nutrients, production of wastes, and production and utilization of public goods. The intensity of influence depends on external factors like mutual distance of colonies, medium composition and rigidity, or possibility of mutual signal molecule exchange. In this bachelor's thesis there are described known mechanisms of intraspecies interactions that may be of some importance in communication between two colonies. In more detail there are described three particular cases of influence of two nearby colonies that have been up to now studied more intensively. Further on, there have been summarized methods of measuring the sizes of colonies and algorythms applicable to evaluation of mutual influence of nearby colonies.
