Tween 80 is used in USP 23 methods <61> with no known effect of spore
germination or bacterial growth--except it enhances injury recovery of stressed
microbes. It does this by neutralizing many antimicrobial agents--I suscpect it
will also do this in the soil at least initially.  You can contact the
manufacturer for the biodegrade data.
