International audienceBACKGROUND Clofibric acid (CLF), the main pharmacologically active metabolite of blood lipid regulating pharmaceutical clofibrat, etofibrat, etofyllinclofibrat is one of the most widely reported drugs found in water. It is hardly or not degraded by the conventional technology used in wastewater treatment plants. RESULTS Sixteen new filamentous bacteria belonging to genus Streptomyces spp. isolated from different Romanian soil samples and three strains from a collection of microorganisms (MIUG) were morphologically characterized, tested based on their resistance against clofibric acid toxicity and then investigated as bioremediation agents. Only five Streptomyces spp. isolates coded MIUG 4.88, MIUG 4.89, LP1, LP2, SNA, showed high CLF tolerance at most of the concentrations tested (0.2, 0.5, 1, 5, 8 mg L−1). CONCLUSION The data obtained showed that only the strain Streptomyces MIUG 4.89 presents promising potential for clofibric acid biodegradation, with an elimination yield of 35%, which was not reported for this class of bacteria to date. However, further research is needed for optimization of the CLF biodegradation conditions to enhance its bioremediation yield especially in polluted aquatic systems. © 2016 Society of Chemical Industr

“…[26] The most widely recommended media formulations for the isolation of these bacteria include starch and malt extract-yeast extract agar. [27] For isolation, approximately 5 g of treated soil samples was suspended in 45-mL sterile water and then stirred for an efficient homogenization. Samples were then serially diluted up to 10 −5 with sterile water.…”

Carbamazepine (CBZ) is a recalcitrant xenobiotic pharmaceutical pollutant highly stable in soil and wastewater during treatment. The biodegradation of CBZ using streptomycetes has been few studied up to now. Sixteen newly filamentous bacteria belong to genus Streptomyces spp. isolated from different Romanian soil samples and three strains from a collection of microorganisms (MIUG) were morphologically characterized, tested based on their resistance against CBZ toxicity and then selected as agents for bioremediation. Five Streptomyces spp. strains coded MIUG 4.88, MIUG 4.89, SNA, LP1 and LP2 showed CBZ tolerance at all of the tested concentrations, i.e. 0.05, 0.2, 1, 5 and 8 mg L⁻¹. Two of these (MIUG 4.89 and SNA strains) were selected based on their resistance to target compound and were then assessed for CBZ biodegradation. The strain Streptomyces MIUG 4.89 showed an interesting efficiency for CBZ removal, with a yield of 35% when it was cultivated in submerged conditions on a minimal medium supplemented with 5 g L⁻¹ glucose. This ability was linked to extracellular laccase production. These results are promising for the use of these filamentous bacteria as bioremediation agents.
