“…All experiments were carried out in two-liter batch reactors (Biolafitte) containing 960 mL of synthetic seawater (Osswald et al 1995) and 240 mL of silicone oil (47 V 20, RhSne Poulenc). The reactors were kept at 30 + 1 ° C in a dark room (diffuse light was used when performing measurements).…”

The degradation by a consortium of slightly-halophile marine bacteria of styrene initially dissolved in silicone oil was monitored in batch reactors stirred at 75, 125 and 500 rpm, respectively. In the 75 and 125 rpm cases, the styrene biodegradation rate was higher than the rate of spontaneous partitioning of styrene from the oil to the water, determined under abiotic conditions. Abiotic transfer tests carried out after biodegradation runs revealed that bacterial activity had resulted in a significant increase in the rate of styrene partitioning between the two liquid phases. Even though bacterial adsorption was noticeable at the oil-water interface, this effect appeared to be due to the release by the bacteria of chemicals in the aqueous phase. Similarity with observations made with Triton X-100 suggested that the chemicals released may have been biosurfactants or solubilizing agents.

“…For the biotic experiments, batch reactors identical in all respects to those described above were inoculated with a suspension of a consortium of slightly-halophile marine bacteria obtained as described in (Osswald et al 1995). The pH of the aqueous phase was continuously monitored and maintained at 8 by addition of 2.5 M NaOH.…”
