The above article, published online on 17 April 2012 in Wiley Online Library (https://wileyonlinelibrary.com), has been retracted by John Wiley & Sons Ltd.

The retraction has been agreed following the investigation of concerns raised by Actinopolyspora biskrensis and Penicillium citreoviride on PubPeer [1]. The investigation has identified similarities across 3 panels in Figure 4b: control and 100 and 200 µg/mL. As a result of the investigation, the data and conclusions of this article are considered unreliable.

The authors were informed of the decision to retract the article but did not provide a response.
