encoding scheme – How should I decode this encoded string?

I have string stored in a database column that is “tZTeImWi2yEd6agTADQUY35LDIGhdTFLb82ku+qhhQ=’

I have tried decoding this using python base64 Library and got output like this”b’xb5x9bSxx89x96……”.

Now I’m unable to decode this one. Can you help me out regarding this?
