Abstract
The growth of the bacterium, Burkholderia cepacia (ex Pseudomonas cepacia) CIP 1-2052 is substantially increased when it is supplied with tert-butanol (TBA) or tert-amyl alcohol (TAA) as the sole source of carbon and energy in the presence of at least one cobalt salt, at a concentration of 0.01 to 4 mg/l of medium. The bacterium is degraded to CO2 in the presence of oxygen. The inoculom produced by the process and the degradation process for these alcohols are useful for water treatment applications.
Claims16
A process for preparing an inoculum of Burkholderia cepacia CIP I-2052 bacteria, in which said bacteria is cultured in a nutrient medium containing at least one source of nitrogen, at least one of tert-butanol(TBA) and tert-amiyl alcohol (TAA), and at least one cobalt salt in the presence of air or oxygen with the provision that the final concentration of the cobalt salt in the medium is 0.01 to 4 mg/l.
