Received September 30, 2014, in final form February 20, 2015; Published online February 26, 2015

As a step towards the structure theory of Lie algebras in symmetric monoidal categories we establish results involving the Killing form. The proper categorical setting for discussing these issues are symmetric ribbon categories.

Key words: Lie algebra; monoidal category; ribbon category; Killing form; Lie superalgebra.
