2.3. Microorganisms and cultivations
B. cepacia CCM 2656 (ATCC 17759) was purchased from the Czech Collectionof Microorganisms. The bacterial culture was cultivated in mineral salt mediumdescribed by Bertrand et al. [22]. SCGH, salt solutions and microelement solutionswere autoclaved separately (115◦C, 20 min) and then aseptically reconstituted atroom temperature prior to the inoculation to reach desired portion of SCGH inthe medium and final concentration of salts.
