Resistance to heavy metals and bioaccumulation of lead and zinc by Chryseobacterium solincola strain 1YB-R12T isolated from soil

Résumé

A novel species of the genus Chryseobacterium which was isolated from soil, has been studied for resistance to antibiotics, heavy metals (lead, chromium, nickel, zinc, cadmium, copper, cobalt) and its capacities for bioaccumulation of lead and zinc. It exhibited high Minimal Inhibitory Concentration values for metal ions tested ranging from 75ug/ml to 500ug/, and antibiotic resistance to imipenem, cefuroxim, tetracyclin, nalidixic acid, pipemidic acid, fusidic acid, fosfomycin, cefalotin, dibekacin, furans and nitrofurantoin. The strain was able of accumulate more than 90% of lead and zinc during the active growth cycle. Study of pH effect on heavy metal removal indicated that the metal ions accumulation increased with increasing pH. Since, Chryseobacterium solincola could grow in the presence of significant concentration of toxic metals and because of its high metal accumulation capacity in aerobic conditions, may be potentially applicable in situ bioremediation of heavy metals contaminated aqueous or soil systems
