"The invention's third option allows the addition of oil digesting microbes to the sorbent. A sorbent with such microbes would allow dumping the used sorbent contaminated with oil in the environment. The microbes would provide effective bioremediation of used sorbent. A long shelf-life is possible because the sorbent would include a system for protection of oil digesting microbes together with their necessary nutrients while being maintained in a dormant state until their activity is triggered."

* so you are right bank, it allows the addition, not necessarily always added!

and Claims 8 and 9 talk about the microbes further...

8. The composition of claim 1 further comprising oil-digesting microbes admixed with said substrate and said retardant with said hydrophobic additive, said microbes added at a range of from between about 1.times.10.sup.5 to about 1.times.10.sup.11 of microbes per pound of sorbed liquid capacity of said sorbent substrate.

9. The composition of claim 8 wherein, before addition to said substrate and said retardant, said microbes are mixed with a nutrient formulation, said nutrient formulation comprising a nutrient at least one of which is selected from the group consisting of sugar, wheat bran, hay, seaweed, soy, sodium bicarbonate, potassium, corn starch, ham and cereal husks, and a nutrient salt supplement said nutrient salt supplement comprising disodium hydrogen phosphate, monosodium dihydrogen phosphate, nitrogen, phosphorus, calcium, magnesium, zinc, iron, sodium, mineral salts and sulfur, and a pH buffer in an amount sufficient to achieve a pH of between about 6.8-7.2 when hydrated creating thereby a microbe nutrient mixture.
