Immobilization of Rhodococcus erythropolis B4 on radiation crosslinked poly(vinylpyrrolidone) hydrogel: Application to the degradation of polycyclic aromatic hydrocarbons

The results showed that, the strain fixed is capable of growing in the presence of naphthalene or anthracene as a unique source of carbon. It was also shown that, the fixed strain can be preserved by freeze-drying for further use. The biodegradation capacity was improved during the second use.
