Abstract: An improved microbiological fire-fighting foam which comprises a bioremediating component, surfactants, foaming agents, and inorganic nutrients, the bioremediating component consisting substantially of sporulating bacteria which are tolerant of the surfactants used, the surfactants selected being innocuous to the bioremediating component used both when the microbes are in a spore state and when activated, and the selected surfactants further being biodegradable by the microbes of the microbial solution. Alternative embodiments of the invention include formulations which comprise perfumes and/or preservatives in addition to the constituents mentioned above. The improved formulation enables microbiological digestion to inert volatile organic compounds and hydrocarbons which may indeed be ablaze when applied.
