Abstract: The invention provides methods, apparatuses, and kits for producing ethanol and other alcohols. The methods involve fermenting organic material in a fermentation mixture to a biogas comprising methane; converting at least a portion of the biogas to synthesis gas comprising CO and H2; and contacting at least a portion of the synthesis gas with a catalyst to produce alcohol. In some embodiments, a microorganism that reduces ferric iron to ferrous iron is included in the fermentation mixture to enhance the efficiency of the fermentation and the yield of alcohol.

Abstract: Generation of Fe.sup.+2 for water treatment and treatment process using same.

Abstract: Methods for treating aqueous/sedimentary systems, sediments and soils are disclosed for prevention of activation and for control or clean-up. The method involves intentionally adding to an aqueous system containing unwanted sulfur and phosphorus in the water and hydrocarbons in the sediment, iron species selected from the group consisting of elemental iron, iron carbonates and iron oxides. Iron-phosphorus compounds and iron-sulfur compounds are precipitated and thereby removed from the system. Hydrocarbons are convened into water, carbon dioxide and small amounts of methane. In a practice of this invention, propagation of aquatic vegetation dependent upon phosphorus species and sulfur species is inhibited by the removal of these species therefrom. Heavy metals are inactivated.

Abstract: Generation of Fe.sup.+2 for water treatment and treatment process using a microbe capable of converting Fe.sup.+3 to Fe.sup.+2 wherein the microbe is selected from ATCC 55339.

Abstract: The present invention relates to a floating containment barrier grid structure (20) for containment of floating aquatic plants (26) in a body of water (30). The barrier grid structure (20) includes a plurality of interconnected square barrier segments (24), the top edge of the barrier segments extending above the surface of the water so as to prohibit substantial wave action. The floating containment barrier grid structure (20) being anchored by cables (38) and stakes (40) in a somewhat tensioned state while floating in the body of water (30). The barrier grid structure (20) being tensioned to enable portions of the barrier grid structure (20) to be submerged beneath the surface of the water by a harvesting machine (28) while harvesting the floating aquatic plants (26).
