I have never heard of using hygro in bacteria. Although I have no idea
what plasmid you are using. Are you sure this gene has a bacteral promoter
in front of it? Typically Hygro is used for mammalian cells at a
around 200 ug/ml. You should titrate this amount on non-transfected cells
first to be sure.
