A cooperative behavior is one that benefits an individual (the recipient) other than the one performing the behavior (the actor). [1] This article outlines the various forms of cooperative interactions ( mutualism and altruism ) seen in microbial systems, as well as the benefits that might have driven the evolution of these complex behaviors.
Cooperative quorum sensing, involving microbial intelligence, facilitates natural genetic transformation, a process in which extracellular DNA is taken up by V. cholerae cells. [27] V. cholerae is a bacterial pathogen that causes cholera with severe contagious diarrhea that affects millions of people globally.
Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Quorum sensing is used by both Gram-positive and Gram-negative bacteria because it aids cellular reproduction. Once in a biofilm, bacteria can communicate with other bacteria of the same species. Bacteria can also communicate with other species of bacteria. This communication is enabled through autoinducers used by the bacteria. [13]
The black walnut secretes a chemical from its roots that harms neighboring plants, an example of competitive antagonism.. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
Most bacteria in the human body are actually good for us and help with carrying out necessary life processes. Gut bacteria in humans often aid in the breakdown of foods and synthesize important vitamins that could not be processed by humans alone. [16] Therefore, humans must be careful when taking antibiotics when they are sick. Antibiotics do ...
Early humans were nowhere. A new study from the University of Chicago finds that all humans have an innate sense built in that makes us fear things that are moving closer towards, rather than ...
Protocooperation is a form of mutualism, but the cooperating species do not depend on each other for survival. An example of protocooperation happens between soil bacteria or fungi, and the plants that occur growing in the soil. None of the species rely on the relationship for survival, but all of the fungi, bacteria and higher plants take part ...
