My response:

1) Organic material in a vacuum at a higher temperature than LN but less
than -30 C may last a very long time and be safer than that stored directly in

2) You are right about frozen micro organisms. It is not the activity of living
micro organism that should concern me but the chemicals released by these
organisms before the freezing. I can not think of a way to prevent that right
