Chromobacterium violaceum is one of millions of species of free-livíng microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals [i] extensive alternatíve pathways for energy generation, (ii) 5OO ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motílity, and (iv) wide-spread utílizatíon of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in additíon, a series of previousiy unknown but important enzymes and secondary metabolites inclucing paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multíple chitinases, and proteins for the detoxificatíon of xenobiotics that may have bíotechnological applications. |

Micropropagation requires controlling contamination that might compromise the success of the process. Thermal sterilization is traditionally used; however, costs deriving from equipment acquisition and maintenance render this technique costly. With the purpose of finding an alternative to thermal sterilization, this research aimed at assessing the efficiency and ideal concentration of sodium hypochlorite for sterilization of culture media and glassware used during rooting of micropropagated Gerbera hybrida cv. Essandre. Two experiments were carried out. In the first one, treatments consisted of control I (no sterilization), control II (thermal sterilization), and total active chlorine concentrations of 0.0005, 0.001, 0.002 and 0.003%. In the second experiment, based on the results observed in the first experiment, treatments consisted of control I (thermal sterilization) and II (chemical sterilization), and total active chlorine concentrations of 0.002, 0.0025 and 0.003%. Plant behavior was assessed based on the length of aerial part and roots, number of roots, and dry biomass of plants. Results showed that the addition of an active chlorine concentration of 0.003% to culture media provided total control of contaminants, and there were no significant differences regarding the variables analyzed between plants obtained with thermal sterilization and with sodium hypochlorite sterilization. Thus, chemical sterilization can be used as a replacement for thermal sterilization of nutrition media for rooting of gerbera in vitro.
