There's no inheritence of permissions in *nix.

There is however a way to inherit the group of the parent directory on new
files, by setting the directory with the suid bit (chmod +s).

If this was not done prior to creating the files, and now needs to be done,
you can simply run:

chgrp -R bioserv <root-dir-name>
chmod -R g+rw <root-dir-name>
find <root-dir-name> -type d -exec chmod g+x '{}' \;

... and I think everything would be OK...

HTH,
