A hot topic in microbiology is that of quorum sensing, which refers to single-celled microorganisms displaying social behavior. Small signal molecules are the means of communication through which the microbes can coordinate gene expression within a community. This type of teamwork may be an evolutionary precursor to multi-cellular organisms and may provide possible pathways for improving the use of beneficial bacteria or destroying pathogenic bacteria. So, bacteria cultures may actually have a culture. It’s amazing how the interaction between individual and community can be seen at the tiniest levels as well as the largest levels of “life” in the universe.
