Can I decrypt a partition in Ubuntu which is encrypted using BitLocker (utility of Windows 7)?

view story

http://askubuntu.com – I encrypted a 200GB partition of HDD in Windows 7 using BitLocker. I removed Windows 7 from the PC and installed Ubuntu. Now I can't see the partition which was encrypted from Ubuntu. Question: Is there any way to access or decrypt this partition in Ubuntu? By the way, I know the key which is used in encryption.
