The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.

The process in which single-celled organisms monitor their population density by detecting the concentration of small, diffusible signal molecules produced by the cells themselves.

The set of specific processes that generate the ability of an organism to induce an abnormal, generally detrimental state in another organism.

Any process that modulates the frequency, rate, or extent of carbon utilization.

Any process that modulates the frequency, rate or extent of single-species biofilm formation.
