    Abstract: A high temperature process for leaching selected metal compounds, such as gallium or germanium, from ores containing those selected metal compounds is disclosed. The method generally includes contacting metal-containing ores with an admixture of nutrient medium and bacteria capable of leaching selected metal compounds contained in the ore. Preferably, bacteria designated as ATCC 53921 are used in the method. The ore is typically crushed prior to contacting it with the admixture, and the process is carried out at between 62 DEG C and 75 DEG C and at a pH of between 1.0 and 2.5. The method presents a novel process for recovering valuable metals from ores which are otherwise difficult or impossible to recover. Metals which are particularly recoverable using the present method are germanium, gallium and mixtures thereof.

    Abstract: The invention relates to the use of microorganisms to degrade and remove coatings, such as paint, epoxy resins, and comestible polymeric coatings, from the surface of aluminum beverage cans. The method includes contacting aluminum surfaces with an admixture of nutrient media and bacteria capable of biodegrading paints and epoxies. A preferable bacteria for use in the method is that designated as ATCC #53922. ATCC #53922 is a mixed culture of Pseudomonas picketti and a Bacillus species. The method presents an improved method for recycling coated aluminum surfaces. At present, aluminum products are subjected to incineration to remove the coatings prior to recycling; incineration is destructive of the aluminum product and causes air pollution through release of toxic substances, including dioxins. An apparatus suitable practicing the method is also disclosed, generally comprising a container (13), a temperature regulator (16) and an agitator (14) to mix the admixture inside the container.
